How to dry the floor in the cellar. How to dry the cellar: get rid of dampness, condensation, mold. How to dry a garage cellar yourself

Excess humidity in the cellar occurs due to various factors. The root cause is usually an initially incorrectly designed and built storage facility for vegetables, fruits and canned goods. If the problem already exists, there are well-established, time-tested, budget ways to dry out the cellar. More convenient methods have also appeared, but they are quite energy-intensive and costly in monetary terms. But in any case, after drying the cellar, it is recommended to disinfect it.

Preventing moisture accumulation in the cellar

In order not to encounter the problem in the future of how to dry a cellar in a garage or a private house from dampness, at the initial stages of construction it is necessary to take care of compliance with all the rules and regulations for ventilation and waterproofing (vapor barrier) of the room.

  • It is best to fill the walls and floor with concrete based on high-quality cement (to save money, it is allowed to add low-quality substances to the solution to improve moisture repellency).
  • When close groundwater external waterproofing will be required. It can be either in liquid form or rolled. Water protection is selected based on reliability and financial capabilities.
  • If the cellar is designed on a slope, then drainage pipes will be a mandatory addition to combat the penetration of moisture into the storage.
  • It is necessary to make a special blind area around the entrance to the cellar to prevent precipitation from entering it.
  • Air supply and exhaust ventilation in different corners of the storage (diagonally). A diameter of 12.5 cm is the optimal size for ventilation ducts or pipes. The first pipe is installed 10-15 cm short of the floor - it will be responsible for the supply of air from outside. The second, for exhaust, is mounted below the ceiling level within 10-2° cm. All ventilation is protected from direct ingress of precipitation and debris, but with a good gap. It makes sense to attach a device to the exhaust duct to stabilize draft and circulation. Ventilation pipes are installed vertically; do not tilt the pipe more than 30°. The length of a channel with a slope cannot exceed one meter.
  • The storage room for fruits and vegetables in the garage or under the house is insulated with a vapor barrier to reduce the possible penetration of moisture into the lower (basement, subfloor, cellar) and upper levels of the premises (rooms of the house, garage, utility unit).

Storage floor design

The main reason for waterlogging of the cellar is closely located groundwater. Initial proper floor installation will prevent the problem of excessive moisture in the basement. There are several ways to install a waterproofing floor.

  • Most often the floor remains earthen. Water from the lower layers penetrates through capillaries to the floor surface. To prevent the need to dry out the cellar from dampness, the earthen floor is leveled, compacted and covered with a thick film or roofing felt. To protect the coating from tears or breakage, use wooden boards (possible reasons coverage violations: foot pressure, installation of boxes with sharp corners, careless displacement of heavy objects).
  • An earthen floor can be reinforced by packing clay, that is, covering the entire floor with a compacted mixture of clay and sand. This operation, which allows you to dry the basement by creating a natural barrier for moisture to escape, is carried out in four steps:
  1. One layer of crushed stone or broken bricks, and fill the space between the stones with a thick mixture of clay with the addition of sand (clay is taken with a good percentage of fat content, and the floor level should rise by 15 cm after filling).
  2. The clay is compacted very tightly.
  3. Sprinkle sand onto the compacted floor and rub it in. Remove excess with a broom and dustpan.
  4. The created clay floor must be thoroughly dried for two to four weeks.
  • The most profitable way to improve the waterproofing of the floor and avoid regularly drying out the cellar is to make it concrete and with a good drainage system. True, this is the most expensive method, requiring special knowledge and skills.

If after all the manipulations with the floor the level of humidity in the basement or garage decreases significantly, then you will no longer need to worry every year about how to dry the cellar from moisture (especially during the spring rise of groundwater).

Improving wall waterproofing

Poor moisture insulation of the walls of buildings is another reason for waterlogging in the basement of a garage or a separate cellar. Brick walls have many pores through which moisture penetrates and condenses out. The problem can be solved in several ways:

  • Create external insulation from moisture. If possible, remove the soil from the walls and apply a two-layer bitumen mastic or resin.
  • Make an internal waterproofing layer (use special impregnations with a penetration depth of up to 0.5 m to clog the pores of the cellar walls).

Good supply and exhaust ventilation and sufficient waterproofing of the floor and walls will be the key to a dry basement. But how to dry the cellar when water has already penetrated inside and begun its negative impact? The choice of method to combat dampness depends on the availability of ventilation in the cellar.

Dehumidification of a ventilated basement

In any type of basement you will have to carry out whole line works, but first it is necessary to remove from the cellar the supplies stored there, dismantled structures (shelves, racks, flooring), storage containers (boxes, crates, barrels). All wood structures must be dried in the sun and treated with a 5-10% solution copper sulfate, regardless of whether they were damaged by pathogenic microflora.
The second step is to whitewash the walls with a double layer of lime.

  • The lime is diluted so that the solution does not drain from the paint brush (you can add a 5-8% solution of copper sulfate).
  • Divide the lime powder into two equal parts.
  • The first part, using a paint brush, is made in the corners of the cellar and thrown with force onto the walls (you can also onto the ceiling), without trying to get flat surface, but not forgetting about safety precautions.
  • A day later, the second part of the solution is also smeared on the walls.

The end result on the third day internal surfaces cellars become porous and lumpy. Moisture in the form of condensation is not retained on them, since the lime takes water inside itself. Once dry upper layer lime, it’s time to start drying the basement.

Scheme for drying a cellar with ventilation

1. Check whether the ventilation is properly arranged (if the shortcomings are not corrected, the cellar will have to be dried again, almost a couple of days after the drying procedure).

2. Check the cleanliness of ventilation ducts or pipes (remove all dirt, mold or moss growths).

3. Strengthen the air ventilation process:

  • Installing a fan on the exhaust pipe. At open doors and hatches, the cellar will dry out (depending on the amount of accumulated moisture and weather conditions) in the interval from 3 to 10 days.
  • Organization of increased ventilation using a small heating device (candle, dry alcohol tablet, alcohol burner). To do this, extend the ventilation pipe above the ceiling so that a heating element on a non-flammable stand can be placed under it. Warm air will increase circulation and speed up drying of the basement.


4. Warm up the cellar if forced ventilation is unable to dry out the basement. The drying process using heating is carried out in stages:

  • Take a metal bucket (preferably not new).
  • We make many holes in it, both in the walls and at the bottom.
  • Fill the charcoal almost to the top edge of the container.
  • We light the contents of the bucket and wait for steady combustion.
  • We lower a bucket of coal on a leash inside the cellar (the bucket should hang in close proximity to the bottom of the storage and a fire-resistant substrate must be placed under it).
  • Close the cellar lid tightly (as tightly as possible so that the smoke escapes into the ventilation).
  • We periodically open the hatch cover to allow oxygen to enter the room being dried or increase ventilation using a vacuum cleaner through the supply pipe.
  • Remove the bucket of burnt coals.
  • Seal the lid tightly for three to four days.
  • We ventilate the dried and disinfected cellar.

Do not forget that the decision on how to dry the cellar must be safe both for those who warm it up and for the room itself. Combustion is always fire, smoke, carbon monoxide.

With this method of draining the basement, the bucket can be replaced with other heating devices. A small stove - a potbelly stove, a heat gun with good power (more than 3 kW), working kerosene gas, a gas burner (be careful - open fire) is quite suitable.

Drying the cellar without ventilation

A cellar that is not equipped with ventilation naturally accumulates dampness. Here the question arises: how to dry a cellar without ventilation and at the same time not cause harm to health from smoke or carbon monoxide? The answer is obvious - this cannot be done. You will have to install at least simple ventilation.

Before installing ventilation ducts, you can collect moisture in the basement in several simple ways. To do this, you will need materials with a high level of hygroscopicity:

  1. Sawdust - regularly change wet to dry.
  2. Calcium chloride - place around the perimeter and in the center of the cellar (you can calcinate it, not forgetting that it is caustic, and use it many times).
  3. Place slaked lime along the walls and on shelves.
  4. Ordinary thick cardboard from furniture packaging or boxes - lay out dry ones and change when wet.

In addition, there are high-tech ways to dry the cellar from dampness. For example, dehumidifiers, which are most often used for rooms where there is open water(swimming pool, jacuzzi, decorative pond). True, the cost of a dehumidifier ranges from 20 thousand rubles and more. But they will properly perform their function when draining a damp basement; you just need to drain the water they collect in a timely manner.

Ways to combat pathogenic microorganisms

Excess moisture that is not dried in the cellar in time leads to the massive development of harmful microorganisms. All kinds of mold and fungi multiply rapidly and cause harm to both all wooden structures and those stored in open form products. Spores of harmful microflora have a very detrimental effect on a person in an infected basement.
There are the following available funds to combat pathogenic microorganisms:

  • Quicklime (install a barrel of lime in a ratio of 3 kilograms of dry lime per 1 cubic meter of volume, fill with water, leave the room, seal the basement, ventilate after two days).
  • Sulfur checker (you must first remove metal objects from the cellar or cover them with a layer of lubricant. Place the checker on a fireproof stand, light the wick, trying not to inhale the smoke, quickly leave the room being processed, tightly close the hatch and ventilation, ventilate for 24 hours every other day).

How to deal with humidity after a flooded cellar

Flooding of the cellar can occur due to rising groundwater, penetration of precipitation, or accidental flooding. The reason is not important when it is necessary to decide how to drain the cellar from groundwater or how to dry the basement in the garage from excess moisture. The scheme is simple:

  1. Use a pump or drainage pump to pump out water from the storage floor.
  2. Clear out the basement.
  3. Dry for a couple of days with the hatch open and ventilation.
  4. Collect trash.
  5. Whiten with lime.
  6. Dry the cellar using one of the above methods.

There are settlements where flooding of the basements of private houses and cellars occurs regularly. In this case, it is necessary to strengthen the floor drainage.

Dampness in the cellar is a common phenomenon that all residents of the private sector struggle with from season to season. Excess moisture may appear in the form of condensation on the walls and ceiling due to insufficient measures to waterproof the room; water may form on the basement floor due to the proximity of groundwater or due to spring floods. The products themselves can become a source of unwanted moisture if they are collected at the wrong time or not dried enough. In itself, water is not dangerous, but it leads to the destruction of the building and all its parts, in addition, it contributes to the appearance of aggressive mold, mildew and various insects.

This article will be devoted to how to dry the cellar, because it is simply necessary to deal with excess moisture in the basement, otherwise it will not be possible to preserve food.

Rules for pre-drying the basement

Drying cellars and basements is necessary in the summer, when the weather is warm and dry. It is recommended to start this procedure as early as possible, preferably immediately after the rainy season. Activities to dry the cellar can last from a week to a month and a half - depending on how wet all the walls and floor are.

You need to start drying the cellar with natural measures, and if they are insufficient, you will have to move on to the second stage - forced drying.

Here's how to dry out your basement naturally:


Attention! If earthen floors are used in the cellar, it is recommended to replace the top layer annually. To do this, soil contaminated with mold and fungus is cut off and taken outside. Instead of this layer, a layer of dry coarse sand is poured onto the basement floor.

How to dry a cellar without ventilation

Drying the cellar with a candle

This method is very ancient, it was used hundreds of years ago. To make drying using this method possible, the basement must be equipped with an exhaust pipe, which is usually located under the ceiling of the room.

The candle is placed in a tin can and placed directly near the cellar ventilation. It is imperative to extend the main pipe by installing a metal corrugation or tin pipe on it.

A small candle warms up the air at the inlet of the pipe, because of this it begins to circulate faster through the basement, and the draft increases. As a result, the air temperature in the cellar does not increase, but natural ventilation increases - the walls and floors dry much faster.

The cellar doors or hatch must be open when using this method!

Important! Instead of a regular candle, you can use dry fuel tablets. This substance, when burned, releases disinfectant gases, which will not be superfluous in the fight against mold and microbes in the basement. To dry the cellar you will need to burn 10-15 tablets.

Drying the cellar with electrical appliances

This method turns out to be quite expensive, since a lot of electricity is spent during drying the cellar. There are two types of heaters you can use in the basement:

  • Closed heaters, such as oil, infrared, convector. The electrical appliance is placed in the center of the cellar and evenly heats the air in the room. It will take at least ten hours to completely dry out the basement; sometimes basement heaters need to run for several days.
  • The electric gun is designed for drying rooms after flooding, so it is perfect for seasonal drying of basements. This device is very powerful; a heat gun can dry out a cellar in just a few hours, so the whole process will be cheaper than with a household heater.


Attention! If you have dirt floors in your basement, you will need to place a rigid base on them for the electric heater.

Drying the cellar with a fan

Typically, cellars are dried by opening the doors on warm, dry summer days. Can be accelerated natural process by installing a fan in the middle of the stairs. A prerequisite for this method is the presence of an exhaust pipe in the basement, because the fan only accelerates the air, accelerating circulation.

Depending on the size of the cellar, complete fan drying may take three to five days.


Advice! Fan blades inserted directly into the duct of a basement ventilation system are very effective.

Using a potbelly stove in the basement

A potbelly stove type stove turns out to be very effective in drying out cellars. However, such a stove is not found in every private household. Those who have a potbelly stove can dry out their cellar very cheaply and quickly.

The potbelly stove is placed inside the basement so that its pipe fits into the exhaust vent of the ventilation system. Whether the stove is heated with wood or coal - it doesn’t matter, the main thing is that the heat in the basement is sufficient.


Hot smoke coming out of the stove's chimney speeds up air circulation in the basement ventilation duct. Additionally, the hot walls of the oven heat the room, drying out mold and mildew, eliminating condensation and excess moisture from the basement.

The stove method is considered a fire hazard, so there should be no wooden objects or other flammable materials inside the basement at the time of drying. You cannot use a potbelly stove in those cellars where the ventilation is made of plastic - the pipe will simply melt from the heat of the stove.

What to do with the cellar after drying

After ventilation is completed, dried shelves are installed, boxes and bins are brought into the basement, boxes and boxes for vegetables or fruits are placed inside the cellar.

In general, excess moisture in the basement should alert the owner: if condensation appears, the walls or floor become wet, it means that something was done wrong at the stage of building the cellar.


There are several methods to improve the waterproofing of an underground storage facility:


In a dry basement, mold does not spread, fungus does not settle here, there are no bacteria or harmful insects, so the products are perfectly stored, remaining just as tasty and healthy until the next season.

There are several methods for drying a basement; each owner can choose the one that is more convenient and appropriate for him.

In most cases, the appearance of dampness in the garage basement is caused by mistakes made during the construction stage. And the most interesting thing: it is almost impossible to take into account all the nuances and provide for every possibility of moisture entering the cellar. And it’s good if there is no groundwater around, and none of the neighbors equip it in the immediate vicinity storm sewer. But a huge number of owners of garages with a basement still have to face a significant problem in the spring and autumn - how to dry the cellar. In our article, we will not only look at the main methods of drying a room, but also provide some tips on how to properly waterproof a basement.

You need to think about preventing the appearance of dampness in the cellar at the construction planning stage. When constructing a basement, under no circumstances should you use porous materials such as expanded clay or foam blocks. It is also not recommended to use any type of brick, since in practice it is very problematic to ensure proper water resistance of this material. The best option is concrete, not only for the bottom of the cellar, but also for all the walls.

Tip: it is best to carry out an external drainage system simultaneously with the construction of the garage basement.


After washing and drying, chests, drawers, shelves and other parts exposed to air can be covered with a layer of whitewash with the addition of a solution of copper sulfate (about 100 g per bucket of ready-made lime).

  • It would be useful to fumigate the room with sulfur - it leads to the death of microorganisms, insects, and prevents the invasion of rodents. To do this, use special smoke bombs, which can be purchased at agricultural equipment stores. It is clear that when carrying out such fumigation, all precautions must be strictly observed, since the smoke from these bombs is very harmful to the human respiratory system.
  • After initial ventilation, it is necessary to clean the walls and floor of the cellar from plaque and debris. All surfaces should be treated with a “strong” solution of potassium permanganate. If the cellar room has an earthen floor, then it makes sense to cut off the top layer of soil, since it is often affected by putrefactive bacteria or mold. Instead, you can backfill with clean, dry sand.

If the measures taken are not enough, and the humidity in the cellar remains high, then you can proceed to final drying of the room, which can be done in several ways.

Methods for forced drying of the cellar

Using a Dutch oven

For a long time, we have been using the method of drying the cellar using a brazier, which you can make yourself from an old metal bucket or other container.

A fire can be lit directly in it by first making several holes in its lower part to create draft. You can install a cast-iron or home-made grate from a metal rod, and completely cut off the bottom. Legs with a height of approximately 100 ÷ 150 mm are required. In addition, a hook with a cable or wire is prepared, on which the brazier will be lowered into the cellar.

There should be no flammable materials at the site where this fryer will be installed. If the floor in the cellar is wooden and cannot be removed, then using this method is prohibited.

Charcoal or firewood can be loaded into the prepared brazier, and the fire is ignited using splinters or fireplace liquid. Then, the brazier is lowered down on a rope. All that remains is to monitor the combustion and the need to add fuel. Thanks to the blowing from below, a strong draft will be created in the fryer. The fire must burn continuously for 10 ÷ 12 hours.

Hot air will quickly fill the room, warming it up and removing unpleasant musty odors, as well as disinfecting surfaces with smoke. In a well-dried room that smells of smoke, colonies of microorganisms should not develop or harmful insects should appear.

It is best to install the brazier, if possible, in the middle of the cellar, then the smoke will evenly cover the entire room and go into the ventilation pipe. For this drying method, it is optimal to use dry birch or linden logs, since this wood has disinfecting properties and removes unpleasant odors well.

It is strictly forbidden to go down into the cellar during such fumigation - it is mortally dangerous. All actions with the brazier are performed only outside, after raising it to the surface on cable

Drying the cellar using a candle

Another fairly popular method is to dry the cellar using a regular candle. It is installed in an iron can and placed near the exhaust ventilation pipe, and front door or the hatch is kept open for drying.

It is advisable to place the candle as close to the floor surface as possible. The exhaust pipe is expanded with an additional tin link.

It would seem that a very small flame of a candle creates intense draft, therefore accelerating the air circulation inside the room. The faster the accumulated musty air of the cellar comes out, the faster fresh warm air from the street will get there. In this case, the drying of the entire room is not due to its heating, but rather due to the rapid replacement of air, that is, intensive ventilation.

The candle, if desired, can be replaced with an alcohol burner.

This ventilation process can last for several days, depending on the humidity of the cellar. A burnt-out candle is replaced as many times as needed until all surfaces of the cellar are dried.

Using dry alcohol

This method is practically no different in technology from the one described above - instead of a candle, dry sleep tablets are used. However, it also has its own advantage.

Using electrical appliances

Drying the cellar using various electric heating devices can be classified as the fourth method. For this, a closed type heater can be used, for example, oil, infrared or convector. It is installed in the middle of the cellar with the expectation that thermal radiation will spread evenly over the entire area of ​​the room.

Naturally, if the cellar has an earthen floor, then a rigid base needs to be prepared for the heater.

If you decide to carry out drying with an electric heater, you need to be patient, as this process may take a long time. You also need to remember that heaters, as a rule, always have high power consumption, and this activity will not be cheap. Therefore, if it is possible to use another drying method, it is better to abandon this method.

Separately, it is worth mentioning the heat generator (it is often called a heat gun), which is very often used for drying various rooms. Moreover, it is used not only for drying rooms with high humidity, but also for rooms that were located in flooded houses. Thanks to the power of thermal radiation and the fan built into such a gun, drying the cellar occurs quite quickly. Although such a heater also consumes a lot of electricity, the drying process can be even cheaper than weeks using conventional heating devices, due to the fact that the procedure will take much less time.

Application of forced ventilation

Some owners of private houses with cellars do not rack their brains much over the question of how to dry out their pantry. Several times during the summer, they open the front door leading to the basement and install a fan in the middle of the opening or on the stairs, which will increase air movement. In this case, the drying of surfaces will not take place under the influence of heat, but by ventilating excess moisture.

This drying method is best suited for cellars where an exhaust hole is installed and the process will take from three to five days, depending on the volume of the room.

Folk craftsmen come up with and own designs with large and small fans, for example, by temporarily or even permanently integrating them into the exhaust ventilation pipe. An example of such a design can be found by watching the attached video:

Video: homemade duct fan for drying the cellar

Using a portable stove

Many people are accustomed to drying their pantries using small stoves heated with wood. The pipe from the stove is led to the exhaust vent and the front door or hatch opens. To achieve the desired success, this event is carried out over 3-4 days. The draft created promotes good air circulation. In addition, direct thermal radiation from the walls of the potbelly stove also plays a role.

This drying method is quite fire hazardous. In addition, it cannot be used if the exhaust ventilation duct is made of a plastic pipe, which will simply begin to melt from the high temperature of the exhaust smoke. You can, of course, use a flexible fireproof hose or a prefabricated metal structure to organize a temporary chimney, but this looks too complicated and costly.

Treatment of the cellar after drying

After drying, before bringing in and installing all treated wooden structures, you should carefully check the condition of the floor and walls. Perhaps the reason high humidity lies in the fact that they have not received sufficient waterproofing, and ground moisture freely penetrates into the cellar. If this is the case, then appropriate measures should be taken.

If concrete surfaces have been dried, it is recommended to treat them with waterproofing compounds, which in the future will not allow excessive moisture to reappear in the cellar.

  • Today, a lot of materials are produced for waterproofing, but for concrete surfaces, an impregnating option is perfect, which is capable of penetrating deeply into the concrete structure.

Impregnation is applied in several layers, each of which must penetrate to a certain depth and dry well. The composition closes all microscopic pores of concrete and crystallizes inside. It creates a reliable barrier to moisture, and at the same time allows the material to “breathe”.

You need to work with impregnating waterproofing compounds very carefully, wearing a protective suit, gloves and a mask that covers the respiratory system, otherwise you can get burns to the skin and mucous membranes. After absorption and polymerization, such a composition poses absolutely no danger to human health or to the safety of products.

  • Another option that is suitable for waterproofing a cellar is the familiar roofing material. But this material can also only be laid on concrete surface, which is pre-coated with mastic. Then the mastic is heated with a burner, roofing material is glued to it and pressed well to the surface. Separate sheets are laid overlapping each other and form a solid surface, which also protects well from the appearance of moisture from the ground.

If it is not possible to use modern technologies for arranging a cellar, or preference is given exclusively to natural materials, then you need to secure at least the floor of the room. To do this you will need a natural material- clay . This method of waterproofing a floor is called padding, and for it it is necessary to choose clay with the highest possible percentage of fat content. In addition, you will need stones or broken bricks, which will become a strengthening link in creating a clay coating.

  • Stones are poured over the entire surface of the floor, and a solution of rubbed clay is laid on top of them and not large quantity sand, 120 ÷ 150 mm thick. The consistency of the solution should be quite thick.
  • The clay is spread over the surface and then compacted between the stones using a tamper, adding mortar until it completely covers the stone mound.
  • After the floor becomes smooth and dense due to the stones and tamping, coarse sand is poured onto the still wet surface in a layer of 50 ÷ 70 cm. It is compacted as much as possible into the clay surface until it becomes dense. The remaining sand that could not be driven into the clay is swept away from the surface. If you need a perfectly smooth surface

    Grouting a clay floor

    • This is followed by a long drying of the clay floor with the hatch or door to the cellar open. This process can take from 15 to 40 days, so it is better to start working on it in early or mid-summer so that the surface is completely ready for use by autumn.

    The walls of the cellar can also be coated with clay. But first you need to make a wire mesh on the walls, which is fixed to the earthen surfaces using wire staples.

    Then, a thick clay solution is poured onto the reinforced base and left to dry. There is no need to level this layer. Next, the following is superimposed layer of clay mortar, which usually leveled manually, in a circular motion, or in the same way as the floor - using wooden grout.

    In addition to these types of waterproofing, there are others, for example, liquid rubber or glass. You can choose any of them that seems more affordable, but waterproofing is a must. It will help protect the room from the penetration of ground dampness, and therefore from the occurrence of fungal colonies and mold stains, the presence of which negatively affects the safety of vegetables and fruits.

    After drying and waterproofing work is completely completed, you can bring in and install all the “interior” items of the cellar. After competently and fully carried out preventive measures, the degree of safety of products placed for the winter will be much higher.

    Video: how to defeat dampness in the cellar - theory and practice

The cellar always maintains a low temperature, which ensures the safety of food. However, low temperatures and insufficient air access lead to dampness and, as a result, mold. In addition, in spring there is a risk of flooding the cellar with melt water. And even if you forcibly pump out all the liquid, the room will still remain damp. Therefore, the owners are faced with the question: how to dry the cellar? Let's look at all the main methods and determine how effective they are.

How to dry a cellar outside

So, we have a cellar on the street, for example, in the country. How does this structure differ from the underground floor in the house? As a rule, such a cellar is a single structure or pit connected to non-residential premises. This means that drying and disinfection can be carried out here using fire and smoke.

How to dry a cellar using a roasting pan? First, the racks and shelves are taken out of storage - they can be dried in the sun and treated with a solution of copper sulfate, which will prevent the development of mold. We light a brazier (it’s easy to make from a bucket) and lower it on a hook into the hole. The heat will promote drying and the smoke will disinfect the room.


You can also dry out the storage by creating additional traction. To do this, we extend the supply ventilation pipe using tin cans almost to the floor and place a candle near it.

Both methods are not fast, and drying may take several days.

How to dry the cellar in the house

The easiest way to dry out vegetable storage in your home is with a regular heater. You need to take an extension cord, lower it into the cellar and connect any heater closed type(no open spiral). The type of device is chosen for safety reasons, since a person cannot stay in the cellar all the time. It is also necessary that the heater has a fuse that will turn off the device if it overheats. Drying time will depend on the power of the device and the area of ​​the room, but, as a rule, it happens quite quickly.

How to dry a cellar using a heat gun? This method is rarely used in private homes, but these devices are used to get rid of dampness in industrial premises. Heat guns are highly efficient fan heaters. They are used both for heating large rooms and for drying. The disadvantage of this method is that you will have to buy special equipment, and, most likely, this explains the rare use of the method when drying private cellars. However, recently it has become possible to rent heat guns, or, as an option, order dehumidification of the room from a specialized company.

So, now you know how to dry out the cellar. However, it must be remembered that it is best to foresee the possibility of this problem occurring during the construction stage. Analysis of the groundwater level at the selected location and installation of supply and exhaust ventilation will reduce the appearance of dampness and mold during operation of the cellar.

Garage owners sometimes face the problem of high humidity in the cellar built there. This affects the properties of the metal and the storage conditions of the products. Sometimes such situations arise at certain times of the year. But it also happens that the appearance of water is associated with omissions during construction work. Regardless of the reason for the appearance of condensation, the question arises - how to dry the cellar by removing condensation and dampness.

Prevention Methods

In order not to encounter moisture in the cellar, it is worth considering the following conditions when designing the room:

  • When choosing wall materials, preference should be given to hydrophobic materials characterized by poor water conduction properties. Such materials include concrete grade M 400 and higher. You can also use additives in plain concrete to increase its water-repellent qualities.
  • The use of external waterproofing prevents the penetration of groundwater from the outside.
  • Installing a blind area around the garage will drain water resulting from rain or melting snow.
  • Ventilation pipes should be located in the cellar. The channel for air flow should be almost at the height of the floor (more than 10 cm). Exhaust pipe located under the ceiling surface (10 cm below). Equipping the outside of the pipes with an umbrella will prevent precipitation from getting inside the cellar. For creating great strength exhaust air ducts should be made in a straight shape. If it is not possible to install pipes in a straight position, the side outlet is located at an angle of at least 60° with respect to the horizon. The slope should have a length of no more than 100 cm.
  • Having a vapor barrier between the basement and the room above will prevent moisture from entering.
  • If there is an earthen floor, the penetration of moisture into the cellar increases. When compacting and covering the floor plastic film Humidity levels are decreasing. Installing a concrete floor with waterproofing will protect against condensation.
  • The presence of waterproofing and vapor barrier of the walls will reduce the hygroscopicity of the material. External insulation is carried out by coating the outer sides with mastic. Cement-based compounds are used for internal insulation.

Drying a ventilated basement

Before draining your basement, you should do some preparation. To do this you will need lime and copper sulfate. After removing all the shelves and drawers, you need to check for the presence of mold deposits. If they are available, then wooden surfaces are treated with copper sulfate dissolved in water. The concentration of the solution is 5-10%.

The area inside the cellar is whitewashed with lime. Take a thick mixture of limestone with an admixture of copper sulfate (5-10%). The corners should be coated well. Spray the surfaces in the room with a brush with a thick solution of whitewash. After the lime has dried, reapply another layer. When the walls are dry, you can dry them.


How to dry a cellar in a garage if at first there was no condensation, but then it appeared. The cause may be clogged air ducts. When cleaning pipes, moisture disappears. But it happens that moisture remains. Then, it is necessary to carry out the process of activating the movement of air masses in the following ways:

  • Install a high power fan on the draft pipe. Open existing hatches and windows. The drying period lasts 3-10 days.
  • Apply heat using a candle. To do this, the air duct for the outflow in the cellar is extended and a burning candle is placed under it. It is possible to use dry alcohol. Under the influence of heat, the pipes dry out and good traction appears.
  • Heating the room using a “brazier”. It can be a bucket with holes or another metal container. Smoldering coals, coke, and coal are placed in the container. Then the bucket is placed in the cellar, the door and windows are closed. Sometimes doors should be opened slightly to allow fresh air to enter. After the coals go out, you need to re-ignite them. After all the coals have burned out, the bucket is removed. The usual one of these buckets is enough to dry the cellar.

In hot weather, there are situations where increased air movement leads to increased condensation. This is due to the temperature difference between inside and outside the room. In this case, ventilation is not carried out. On the contrary, you need to close all the hatches and windows. After the air temperature drops to +10°, carry out ventilation actions using one of the methods.

You can dry the cellar in winter by using other heaters:

  • Heat gun 3-5 kW;
  • Kirogas;
  • Potbelly stoves;
  • Propane burners.

When using such methods, you need another person for backup.

The process of drying a cellar in the absence of ventilation


In the absence of a ventilation system, some kind of pipes should be installed. You can run the pipe into the wall or ceiling. Another option is to purchase a fan with a supply and exhaust mechanism. A cellar without ventilation is dried using hydrophilic materials:

  • Dry sawdust, the scattering of which helps to reduce humidity levels.
  • Slaked lime, laid out on shelves and along walls, removes moisture and helps destroy fungus.
  • Calcium chloride, which has moisture absorption properties. For 1.5 liters of water, 1 kg of substance is required. After calcination of the wet composition, you can use it again.
  • Dry cardboard boxes used to eliminate condensation on the ceiling.

You can also purchase special equipment - a household dehumidifier.

After flooding, the cellar should first be pumped out. And then take it all out. After drying, with doors and hatches open, whitewash with lime. After this, apply the described methods.

Isolation from moisture using drainage

When insulation is installed during construction, moisture problems disappear. But it happens that moisture still appears. Then external and internal drainage methods are used.


External drainage involves draining water into sewer outlets. External drainage stages:

  • Digging a trench 40-50 cm below the cellar floor level;
  • Wells are made at separate two-meter distances into which the tubes are inserted.
  • Geotextiles are placed in the trench to prevent flooding.
  • Fill the trench with gravel or sand and lay geotextiles on top.
  • Compacting soil over the trench.

Internal drainage is used when draining a large cellar. Drainage stages:

  • Digging trenches indoors about half a meter deep.
  • Geoseptic material is placed at the bottom of the trench.
  • Sprinkling gravel into the trench at a distance of 15-20 cm.
  • Laying drainage pipes maintaining a slope of 3 mm per meter of pipe.
  • Coating pipes with gravel mixture.
  • Laying geotextile material.
  • Filling trenches with sand or earth.
  • Install the block at the lowest point of the floor. You can buy it or make it yourself, providing a hose for draining water.
  • Equip the well with a pump to pump out water.

It is better to equip drainage systems during the construction of the cellar.

Different methods are suitable for different cellars when removing moisture. You can use a home-made dehumidifier for the basement or think about removing excess moisture during the construction stage.

As a result of poor-quality or damaged waterproofing of walls, storage of wet products, clogged ventilation pipes or errors during their installation, dampness may appear in the basement, and sometimes it is simply flooded with groundwater. In these cases, you need to either warm up the air or create intensive ventilation.

Preparation and initial drying

1. It is more convenient to carry out the procedure in the summer, when most of the shelves are empty. All boxes, drawers, and racks are dismantled and taken out into the fresh air for ventilation.

2. Open the door or hatch to the cellar and leave for two to three days (subject to dry weather). Fresh air will partially reduce the humidity. If the process takes a long time, then the ventilation requires cleaning.

3. If heavy, humid air has difficulty rising through the exhaust pipe, then it is necessary to stimulate the initial natural draft. To do this, a lit torch made of thick paper is briefly brought to the exhaust pipe.

4. If the humidity is very high, then bring in a box with some kind of natural desiccant - charcoal or dry lime; they absorb moisture from the air well.

5. Fumigate the room with a special sulfur smoke bomb. This will help destroy mold, bacteria, insects and repel rodents. Sulfur is very dangerous to human health, so when carrying out processing it is important to strictly follow all precautions.

6. Clean the walls from plaque and debris.

7. Treat all surfaces with a concentrated solution of potassium permanganate.

8. If the floor is earthen, then remove the top layer of soil and replace it with dry, clean sand.

Cover the basement walls of a private house with thick whitewash made of lime with a 5 or 10% solution of copper sulfate. Carry out the procedure wearing protective clothing, goggles and gloves. Special paint brush For whitewashing, similar to a broom, lime is sprayed onto the walls. A day after applying the first layer, apply the second and wait until it dries before proceeding to the main drying stage.

Processing of wooden racks and boxes removed from the cellar:

  • It is recommended to leave boxes, crates and other wooden fixtures in bright sunlight for a while. Ultraviolet light effectively fights moisture, mildew and mold. Very crude structures are burned with a blowtorch.
  • Wash all parts with soapy water and baking soda. Treat surfaces with formaldehyde. To enhance the effect, it is mixed with copper sulfate.
  • Dry drawers and shelves. Prepare whitewash from a bucket of lime and 100 g of 5% copper sulfate solution and cover everything with it wooden surfaces.

You can bring racks and drawers back into the cellar only after the process is completely completed.

Overview of drying methods

1. Candle, alcohol burner, dry alcohol.

The simplest option is a burning candle. It is placed in a metal can directly under the exhaust ventilation pipe. For this purpose, the pipe is extended additional element made of tin, believe me, they leave it open. Drying occurs not due to heating, but due to the fact that the flame creates intense draft and accelerates the replacement of air. The process continues for several days until the dampness is completely eliminated. The duration depends on the humidity level; the method is not suitable for a cellar under a garage.

The candle is replaced with an alcohol burner or dry alcohol tablets, which is not only a good drying agent, but also disinfects. To treat the underground of a private house, 10-15 tablets are usually required. Sometimes the flame from a candle is not enough to quickly begin intense air movement. In this case, first carefully insert a piece of burning newspaper into the ventilation pipe so as not to melt it.

2. Dutch oven.

This method can be used in any room except those located under the garage and those with wooden floors or finishing made of flammable materials. The roasting pan is made from an old metal bucket. Many holes are cut in its bottom and walls with an ax. Legs 10-15 cm high are welded from below, and a hook with a cable or wire is attached to the top.

In a prepared brazier located outside the basement, charcoal or linden or birch logs are poured almost to the top and lit with a torch or fireplace lighter fluid. Then, on a cable, a container with burning fuel is lowered into the underground and placed in the center so that the smoke is evenly distributed and freely exits into the ventilation pipe. The method allows you to not only quickly remove unpleasant odors, dry the cellar, but also disinfect it. The combustion is maintained for at least 10-12 hours, opening the lid every half hour to let in a portion of oxygen. Place a fan on the supply pipe or turn on a vacuum cleaner.

During processing, going underground is strictly prohibited due to high temperature inside and probability of presence carbon monoxide. If the coals go out, then the brazier needs to be pulled out using a cable and re-lit. After drying is complete, remove the bucket of coals and close the hatch or door. Do not look into the basement for two to three days. The smoke will destroy fungus and mold. Instead of charcoal, it is permissible to use stone or coke, but maintaining their combustion is more difficult; you can replace the brazier with kerosene gas.

3. Potbelly stove.

The fuel for the portable potbelly stove is wood. The pipe from it is led directly to the exhaust hole and the door or hatch is opened. The room is heated for 3-4 days. Air drying is carried out due to its intensive circulation and thermal radiation from the walls of the stove. The disadvantage of this method is that it poses a fire hazard; if it is located under a garage or if the ventilation pipe is made of plastic, then the potbelly stove cannot be used.

4. Heat gun and dehumidifier.

The power consumption of the heat generator is high, but due to the fact that the process occurs in a short period of time, energy costs are low. Drying is carried out due to enhanced ventilation and thermal radiation. The use of special air dehumidifiers to reduce humidity is advisable only in the underground areas of large enterprises due to the relatively high price of the equipment (from 16,000 rubles).

5. Closed type heater.

To dry damp basement, closed-type electric heaters are suitable: oil, infrared, convector. They are placed in the center of the room, if the floor is earthen, then on a rigid base. Drying occurs only due to thermal radiation, a process that usually takes a long time. Since the power consumption is high, it is advisable to use them only in cases where there is no other choice.

6. Fan.

During the summer season, you can repeatedly leave this device for several days by opening the door and installing it in the opening or on the stairs. Suitable for removing dampness from ventilated cellars and takes up to 5 days (duration depends on the volume of the room).

7. If increased ventilation does not help.

In hot weather, increasing the intensity of ventilation does not lead to drying out the basement, but to the opposite effect. This is due to the fact that warm air damp from outside. Ventilation during the day must be completely stopped, the supply pipe must be closed, and at night the fan must be opened and installed. If it’s hot at night, then you need to wait until autumn and before the rains start, at a temperature of about +10°C, again use one of the methods suggested above.

Prevention measures

After drying the cellar, measures must be taken to prevent the appearance of dampness in the future. First, the walls and floor of a dry basement are inspected - perhaps the reason is poor waterproofing. In this case:

1. Treat the surfaces with penetrating waterproofing impregnations. They are applied in several layers, allowing each to dry. The product penetrates into the pores of concrete and crystallizes in them, forming a reliable barrier to moisture. When applying impregnation, use protective equipment (gloves, mask). After absorption, the product is not dangerous to human health and the safety of food, the walls remain “breathable”.

2. Another protection option is gluing with roofing felt, suitable only for concrete surfaces. It is glued onto a layer bitumen mastic. The strips are placed overlapping with an overlap of 10-15 cm. Waterproofing can also be created on external walls, and if the groundwater level rises in spring and autumn, then this must be done.

3. A simple method is to fill the floor with clay; for this purpose, take the fattest one. Additionally, you will need broken brick or stone. First, the entire floor surface is covered with a 12-15 cm thick layer of broken brick and sand. The clay is then spread and compacted until it fills the floor and covers the entire stone. Sand that cannot be driven in is simply swept away. If desired, the dried layer is rubbed down to create a perfectly flat plane. Leave the door or hatch to the basement open until completely dry. The process takes up to 40 days.

4. The earthen walls of a cellar in a private house can also be sealed with clay. To do this, a wire mesh is attached to them using staples. Then the mixture is spread on the surface in two layers. The first is not leveled, the second is rubbed in a circular motion until smooth.

5. Concrete walls cover with a layer of liquid rubber (a type of bitumen mastic) or liquid glass inside and out.

6. If the basement is on a slope, then a drainage pipe is placed in the ground above it to drain melt and rain water.

7. A blind area is created around the cellar to remove precipitation falling from the roof.

8. Create or repair a vapor barrier layer between the underground and the room above it.

Dampness can also be caused by clogged ventilation.

Dampness in a garage basement has many negative consequences. This is both poor food preservation and a negative impact on the premises itself.
This can be for several reasons, the most common being poor waterproofing of the room and a leak in the basement of the garage. Today we will look at the question of how to get rid of dampness in the garage basement.
Of course, everything is best done during the construction stage. But measures can be taken to eliminate dampness in the finished building. You will also learn how to dry out the basement in the garage.

How to dry a garage cellar yourself

In particularly rainy and damp weather, many garage owners may encounter certain inconveniences associated with flooding of the garage cellar. This is possible if some mistakes are made that could have been made during construction, since it is quite difficult to foresee and prevent all possibilities of moisture entering the basement.
A certain surprise may be groundwater or the presence of water runoff from neighboring garages directed towards construction.
If flooding does occur, the cellar must be dried. This can be done in several ways.
It is also better to take care of waterproofing the garage cellar in advance (see). Let's consider the basic methods of preventing moisture from entering a room, as well as its subsequent drying.

You can take care of waterproofing in advance

To do this, even before starting construction of the basement and the garage itself, it is necessary to provide for all the nuances of its design, as well as choose the right materials for construction.
After all, the price of the issue is quite high and therefore everything must be done efficiently. You can do all the work yourself and save money.
So:

  • The basement is best made of concrete. It could be poured concrete or concrete plates. This material is perfect for both floors and walls.
    It is better to refrain from using porous materials in the construction of such premises, such as expanded clay, brick, foam block, etc. Such materials have fairly high absorbent properties, which can subsequently cause dampness in the room.
  • You also need to decide in advance on the type of structure. The choice can be made between monolithic and prefabricated and primarily depends on the capabilities of the owner of the building.
    Thus, a monolithic cellar requires a lot of labor, but will also last much longer. Prefabricated concrete block construction is also excellent option and is created much faster.

It is best to build in the summer. This will help prevent the occurrence of groundwater at the site where the pit is formed.

How to dry out a basement

Unfortunately, it is not always possible to provide for absolutely everything during the construction of a basement. And despite the right location and good waterproofing, the basement still becomes damp and humid.
In this case, it must be dried. There are several ways to do this. Let's take a closer look at how to get rid of water in your garage basement.
Before drying directly, the room must be prepared. To do this, you need to remove all objects from it, including shelves, boxes, racks, cans, etc. You also need to sweep out the trash.
After this, the room is usually left for several days to dry with air under natural conditions. This means that the best time for such work is the hot and dry summer period.
Let's see how to dry it using simple and affordable methods. The instructions to follow are quite simple and will not require any costs.
Ways to dry a garage basement:

Using a brazier Drying using a kind of fryer. This is most likely the easiest method for getting rid of dampness in the basement.
  • To do this, you will need a metal bucket, which is installed in the center of the room.
  • A fire is built in it, which must be maintained long enough for the basement to dry out.
  • In addition, the smoke generated during combustion allows you to destroy fungus and mold on indoor surfaces, as well as rid it of rodents and harmful insects.
We use a candle Drying with a candle is also a fairly simple and effective method of getting rid of excess moisture in a room.
  • In this case, a ventilation pipe is constructed that extends all the way to the floor.
  • A metal container is located and secured under it.
  • For the initial draft, a certain amount of paper must be burned in the pipe itself. This craving can be maintained with a candle burning under the ventilation.
  • This process must be carried out for at least three days, during which it is necessary to ensure that the candle does not go out, and also to change the cinders to new candles in a timely manner.
  • Dry fuel can be used instead of candles.

How to properly waterproof a damp room

Still, you can take care of dryness in the garage basement, but this must be done during its construction. For this purpose, waterproofing is used to enhance the moisture-proof properties of the material from which the basement is made. Waterproofing can be carried out in several ways.
External drainage is considered the most economical and effective method of preventing moisture from entering the basement. To do this, groundwater is best drained behind the garage - into the sewer system.
But this method is only possible for individual buildings, which means it is not suitable for garage cooperatives, as well as basement garages big houses. It is best to take care of external drainage during construction, but it can also be done in already built garages.

External drainage

External drainage is carried out using the following technology:

  • First, a trench is dug along the outer perimeter of the garage basement. The trench width is usually about 40 cm; it is dug half a meter below the cellar floor level.
  • Plastic tubes for drainage are placed along the entire trench, the distance between which should not exceed two meters. In order to prevent sand from getting into the tubes, they are covered with a metal grid.
    Wells for installing pipes should not be too deep, this will help prevent sewage water from entering the system.
  • In order to avoid siltation of the bottom of the trench, it is covered with a certain material. In most cases, geotextiles are selected, which are applied not only to the bottom, but also to the walls of the trench.
  • After this, the trench is filled with crushed stone to a level slightly higher than the bottom of the basement wall. You can also use gravel.
  • After backfilling, the trench is carefully covered with geotextile so that the resulting structure becomes a drainage pipe.
  • At the end of the work, this pipe is filled with the remaining soil and the bulk layers are compacted.

Internal drainage

Internal drainage will help quickly solve the problem of moisture in the basement. This method involves placing drainage pipes along the perimeter of the garage cellar, along the entire length of which holes are placed at equal intervals.
Internal drainage must be carried out before pouring the floor, since otherwise the floor will need to be demolished to install internal drainage.

Internal drainage is carried out using the following technology:

  • First, a pre-marked trench is dug, the depth of which usually does not exceed fifty centimeters.
  • The bottom of the trench is carefully compacted. A special material is spread along it along the entire length of the trench, which perfectly absorbs moisture.
  • After this, the trench is filled twenty centimeters with crushed stone or gravel.
  • Drains are installed on this layer of crushed stone. It is very important that a three-millimeter slope is maintained for each meter of drainage pipe.
  • Next, the trench is completely filled with crushed stone. To avoid clogging drainage pipes with small stones, it is better to give preference to medium-sized crushed stone.
  • The trench is finally filled with sand and soil, and each layer must be thoroughly compacted.
  • At the lowest point of the basement, a kind of well is installed in which water will be collected. You can make such a well yourself or buy it at any hardware store.
    PVC wells sold in stores are quite durable and lightweight. Their height may vary, depending on the preferences of the buyer, and reaches three meters.
    They are very easy to install and also easy to use in the future. But still, in order to save their money, some build such concrete wells on their own, thus adding more work to themselves.
  • Placed in the well drainage pump, which will turn on automatically when the float placed in the well reaches a certain level. As a result of the pump operation, water will be pumped out of the well, and the float will lower accordingly.
    Water should be discharged using a hose outside the site, or better yet, into the sewer. To save money, some garage owners use large barrels instead of wells. This is of course possible, but the room will need to be ventilated quite often.


The injection method of waterproofing is considered the most expensive, but also the most effective method of protecting against moisture in the basement.
Its high cost is primarily due to the fact that it requires certain skills and special equipment, so it will not be possible to implement it on your own. But at the same time, such waterproofing works great even in rooms made of foam block or brick.
Protection using injections is carried out using the following technology:
  • In the room, holes are drilled around the entire perimeter, the diameter of which should not exceed 4 mm, and the distance between them should be 80 cm. The distance is determined depending on the density and composition of the soil, the thickness of the walls and other factors.
  • Special expansion packers are installed in the holes. Using a special pump under pressure, insulating substances are introduced into them, which in most cases are certain polymers.

Such waterproofing, unlike other methods, does not depend on the time of year and does not require the destruction of floors or other already constructed elements of the basement.

Attention: Polymer waterproofing materials are considered the most environmentally friendly and at the same time very durable materials. They permanently and tightly fill cracks and voids in load-bearing structures.

Penetrating moisture protection is an equally effective method of waterproofing. With it, new structural bonds are created in the connection, due to which the capillaries and pores are blocked.
To do this, all surfaces of the room are covered with a special material, and there is absolutely no need to excavate the walls.
So:

  • The protective composition is diluted with water and then applied to a previously prepared surface.
    The surface on which the mixture is applied must be moistened in advance for the required reaction to occur. As a result of this reaction, the mixture, entering the capillaries, hardens and fills them.
  • After drying out the garage basement, you can refurbish it with furniture. At the same time, it is better to treat them with antiseptic solutions or ordinary copper sulfate. This will protect them from mold and dampness.

Attention: It is very important to carry out all work strictly according to technology and to the highest quality possible. You also need to choose the highest quality materials. This will prevent you from having to redo the work done.

You now know how to dry a cellar in a garage and how to waterproof it. Before starting work, you should look at photos and videos on this topic and choose the right materials to complete the work.
The most important thing to remember is that you should always prepare the base plane well. This will be the key to high-quality work and the service life of the material.

Dampness in the cellar is evidence of mistakes made during construction. The room may not have had good ventilation or moisture removal. But even a well-designed cellar is sometimes flooded and almost every cellar owner needs to dry it out.

Before the drying process, all old products and wood construction systems must be removed from the cellar. In particular, the following should not remain in the room:

  • pallets for bulk vegetables;
  • wooden shelving;
  • shelves;
  • boxes

The most in a simple way cellar disinfection is whitewashing with lime. It is carried out with a solution of copper sulfate in a proportion of 100 grams per bucket.

To protect structures located in this room from mold and putrefactive fungus a ten percent solution of copper or iron sulfate. With the same solution, before drying, you need to thoroughly rinse all the walls, and also treat the earthen floors.

To prevent dampness from destroying the entire crop, the cellar walls must be dried. During the rainy season in the cool autumn, hoping that the cellar will dry out on its own is very careless.

Traditional methods of drying a cellar

After disinfection and treatment of all surfaces of the cellar, you can safely open ventilation hatches and pipes. The air in this room becomes heavy over time, so you can’t rely on natural ventilation under the influence of draft.

Most Popular traditional methods cellar drying, which you can try yourself:

  • Usage iron stove;
  • Drying using a roasting pan;
  • Using candles (to increase natural cravings).

Using an iron stove

Drying the cellar/basement with an iron stove is a rather labor-intensive method, but effective. If the household has a suitable stove, then simply heat it in the cellar.

Drying the cellar with a brazier

The most preferred option for quickly drying the cellar is to use a roasting pan. The process is carried out a few days after natural drying. A Dutch oven is very easy to make yourself. You can use, for example, an old bucket. The bucket is placed in the center of the room and the fire is constantly maintained in it until the cellar is completely dry.

Small wood chips are used to light the brazier. When the flame flares up and gets stronger, you can put larger firewood in the bucket. The heat quickly displaces damp and stagnant air from the cellar.

Using a candle

An ordinary candle in one single copy will also help to increase air draft in the cellar. However, this drying method requires extending the ventilation pipe installed in the basement almost to the floor (see the figure on the right). After this, a lit candle is placed under the inlet of the pipe. It can be placed in a regular canned food jar.

To create an initial impulse directly in the pipe, it is recommended to light a sheet of paper. This will quickly create the necessary draft in the pipe, which will subsequently be supported by the candle flame. You can completely dry the cellar in this way within three days. Constantly replace spark plugs.

When the cellar is completely dry, you can bring all the removed shelves and racks into it. These items must be checked for dirt and fungi. If lesions are noticed, a solution of copper sulfate will help get rid of them.

Find out how to eliminate dampness in the basement of your home in the article from the same category on protection from dampness, mold and pests.

You can dry the cellar in the garage, or located directly under the house, in no time. To do this, use the heat of the fire and a variety of simple devices. In order for vegetables and rolls to be stored in the cellar all winter, it must be dried in advance.

How to dry a cellar: techniques from experienced summer residents

How to dry the cellar if the basement is made with poor hydro- or thermal insulation? This is a pressing issue for most summer residents and residents of country houses. A wet cellar is unsuitable for proper storage vegetables and preparations for the winter, so today we are talking about ways to remove condensation and improve the functioning of the room.

How to find the source of moisture

It is necessary to drain the basement if:

  • Moisture drips onto the walls and ceiling. To determine the reason why water appears in the basement, you can conduct a simple experiment. Glue a 30x30cm piece of polyethylene onto the previously dried area of ​​the surface, strengthening the edges with sealant. Check the piece after a couple of days. If droplets appear under the polyethylene, then the water comes from the foundation, and if from above (and the place under the polyethylene is dry), then the reason is improper drying of the walls or poor insulation from the outside.
  • The walls become flooded if the blind area is external walls the basement is made without a slope, or the concrete is cracked. That is why, in rainy or snowy weather, liquid accumulates there, seeps down the wall and forms damp spots inside the walls, and water can cover the floor.

  • Liquid can seep into the cellar if the house has no or faulty roof drainage system. Flowing close to the walls rainwater enter the vault.
  • Dense bushes and shady trees growing in close proximity to the basement prevent normal soil ventilation and stagnation of moisture.
  • Water in the cellar may appear due to a malfunction of the water supply system if the pipes are located under the floor.
  • Dampness can intensify when waterproofing in an underground room is destroyed.

Important! It is better to focus on eliminating not the consequences, but the causes of flooding.

Preparatory work before autumn

To begin the drying process, you need:

  • Clear all shelves of stored vegetables and preparations.
  • Dismantle everything wooden elements: racks, shelves, stands, barrels. Take them outside, wash them with hot water and soap solution, dry.

Important! To protect wooden elements from mold, apply a layer of whitewash (lime) with copper sulfate.

  • To prevent the formation of mold, apply an antiseptic impregnation to the wood, which can be purchased at the store.
  • Whitewash the ceiling and walls, and open the hatch door to dry.

Forced drying methods

If all the work does not give the expected result, then you will have to force dry the room. There are main ways to drain a cellar:

  • fryer operation;
  • candles that increase air draft;
  • action of desiccant.

Important! A pump for pumping water out of the basement will help periodically drain a wet cellar when groundwater is high or for cleaning after flooding. We recommend that you definitely purchase such a device; it will become an assistant in many other everyday problems.

Accelerated drying using a broiler

You can get rid of dampness in storage using a regular portable fryer. Before doing this, dry the room naturally, and the fryer will only “finish off” the remaining condensation. The drying process looks like this:

  1. Open all ventilation passages. Light a fire in the brazier.
  2. Lower the fixture to the bottom. This can be done manually or using a rope and hook.
  3. Maintain it only as long as needed to remove the dampness.
  4. According to all the laws of physics, dry and warm air gradually rises, thereby displacing damp air.

Before you get started, there are some things to consider:

  • For ignition, use wood chips and sawdust. Once the fire is established, add larger wood.
  • Do not extinguish the drug until the entire room is filled with smoke and hot air. This kills all biological activity indoors.

Important! It does not always happen that condensation will disappear immediately after the procedure; if necessary, repeat the procedure again.

Drying the basement with a candle

This method is not suitable for all rooms, since you can only get rid of water in the cellar with a candle in small areas.

  1. Place a regular candle in a jar.
  2. Place it directly under the ventilation pipe.
  3. Place burning paper in the pipe, which will give a boost to the draft.
  4. A burning fire increases draft, so moist air is drawn out, giving way to dry air.

Important! This method will be applicable for those who have 3-4 days left for drying. Stock up on a few candles or replace them with an alcohol burner.

Air dryers

To quickly dry a room with a large perimeter, special dehumidifiers will come to the rescue. These devices will allow you to dry and maintain the storage in good condition.

Important! Dehumidifiers are most relevant for large-sized vegetable stores or large cellars. You can purchase them at any hardware store. It is better to ask a consultant, explaining the pressing problems of your storage facility.

The principle of operation is that the air passing through the dehumidifier is cooled, and the liquid settles in a special receiver, after which it settles in droplets into the pan. The peculiarity lies not in heating, but in cooling the air. Modern devices They operate on the basis of freon, just like refrigerators or air conditioners.

Interesting! These devices are suitable not only for the cellar, but also for other rooms.

How to insulate a cellar from moisture

Proper waterproofing of the cellar from groundwater guarantees protection against moisture penetration inside through the foundation of the room. There are several types of insulation.

  • Coating. Treatment of internal and external foundation walls with hard bitumen or mastic using a brush.
  • Pasting. It is made with roll insulating materials like roofing felt. The main disadvantage of operation is the presence of joints.

  • Plastering. Treatment of all foundation surfaces with polymer-cement compounds, which seals all cracks and holes in the blocks.
  • Bulk. Flooring with two-component compositions based on cement and sand (screenings, crushed stone). Filling involves completely filling the floor area so that there are no gaps or untreated areas.

Groundwater in the cellar may periodically appear in small quantities, even if the foundation is isolated. This depends on the location of the room, precipitation and other weather conditions.

  • The heater can be lowered into the cellar if the moisture level does not exceed 60%. You need to monitor its position and not leave the device turned on without your presence at home.
  • A fan heater works on the same principle, but it not only warms the air, but also moves it.

  • IN small room easy to use silica gel. Place it in bags indoors. The granules will gradually absorb moisture.
  • Calcium chloride powder is capable of absorbing moisture in a volume that is twice the volume of the powder itself. Place the preparation on an inclined board. Place one end of the board in any container. Once dried, the powder can be easily reused.

  • High groundwater can be redirected using external drainage system, which will allow them to be removed from the foundation.
  • Mold is washed off with boric, acetic or citric acid.

Eliminating moisture in the basement is a rather labor-intensive process, so it is better to take care of dryness with waterproofing in advance during construction. If a problem occurs, use the proposed methods and extend the life of the cellar.

How to dry the cellar from excess moisture

With the onset of autumn, the life of all gardeners becomes one more problem: how to preserve the entire harvest. It's no secret that all grown vegetables and fruits, and subsequently jars of seaming, are stored in the cellar. But during the summer season the air there became heavy, unpleasant and damp. And here the question arises: how to prepare the cellar for wintering?

First thing

Where can you start all the work? First of all, you need to take everything that is stored inside into fresh air:

All these storage tools need to be cleaned and washed thoroughly warm water with the addition of soap and soda. After which the structures must be completely dried and ventilated in fresh air.

For the purpose of disinfection, everything wooden structures treated with a solution of copper sulfate, and then bleached. If you don’t trust the old “old-fashioned” method, then you can purchase a special antifungal composition that will also do an excellent job with this difficult task.

After carrying out the procedures, you can begin treating the walls and floor of the cellar. First of all, they must be washed and treated with a solution of copper sulfate to prevent the formation of mold. Only after completing these steps can you begin to dry the cellar.

The easiest way to dry

Many may think that just ventilating the cellar is enough. Alas, this is not true. The air in such a room is very humid, stagnant, and most importantly, heavy. This is why simply opening the door will not help. Many people spent their whole lives only ventilating the room and only after a while began to ask themselves the question of how to dry the cellar correctly.

The easiest way to combat musty and stagnant air is to introduce an additional hood. All that needs to be done is to extend the ventilation inlet almost to the floor, and place a jar with a candle under it (it will create the required draft). This way the musty air will leave the cellar. To create initial draft, you can burn a sheet of paper and then place a candle in the ventilation pipe. With the help of such a device, within a few days there will not be a drop of moist air left in the cellar. But do not forget to leave the front door open - this will provide an influx of fresh air.

How to warm up the cellar

Of course, the option with a candle is far from the only one. There are a huge number of ways to deal with excessive humidity. For example, warming up. Today in stores you can find all kinds of special heating devices. They allow you to both dry out the cellar and use them in everyday life for other purposes.

The most popular device is a heat gun. With its help you can warm up the walls of the cellar very well. To do this, you just need to point it in the right direction and leave it that way for a while. Despite the fact that this method is quite easy, not everyone uses it. And then the question arises again, how to dry the cellar outside.

Previously, a fire was simply lit for this procedure. But, of course, this is not the safest option. It was replaced by an easy-to-use device - a roaster. It won't be possible to do it a lot of work. It is enough to take a metal bucket, make legs for it or simply place bricks along the edges and punch small holes at the bottom. Afterwards, you need to load wood chips into this structure and ignite it. When the flame burns well, you can add large logs to the fire.

The brazier is placed in the cellar. The flame from it will not only dry out all the walls, but will also drive out the old, stagnant air, and the smoke will kill all the fungi and bacteria that lived there before. This procedure is more effective than a regular fire, and also much safer.

How to make a cellar well ventilated

Often the air in the cellar is stale and musty, and it is quite difficult to get rid of it. Installing additional ventilation will help solve this problem.

For proper air circulation, it is necessary to make two shafts in different ends premises. For ventilation, it is better to use pipes with a diameter of about 15 centimeters. They must allow air flows in and out. Don't forget about maintaining the temperature. In winter it should be from -2 to +5 degrees Celsius. If everything is done correctly, then the question of how to dry the cellar will not constantly bother you. All that needs to be done is to thoroughly disinfect the room.

How to dry a cellar after a flood

With the arrival of spring, every summer resident suffers. After all, there is nowhere to escape from the melted snow, and all this water will certainly collect in the cellar. So where do you start?

First of all, you need to completely pump out the water. The best way to do this is with a pump. After the water level reaches the minimum value, it is necessary to remove everything wooden structures from the cellar. If possible, throw them away altogether. You can dry the cellar using a brazier. In such a situation, this method will be the most effective (it was described above).

Drying the cellar in the garage

Not all owners store their food and supplies in a room separate from the house. Many people do not have this opportunity, so they set up their cellars, for example, in garages. But here another problem arises: how to dry the cellar in the garage?

Most of the methods described above in the article are suitable for this procedure. But there are more effective means. For example, in any agricultural store you can get advice on how to dry the cellar, and, most likely, the seller will advise using a sulfur bomb for this. In terms of efficiency, it is comparable to a Dutch oven, but does not emit as much heat and smoke.

Those who know how to remove moisture from the cellar using a brazier, and deny all other methods, need to take care of building a hood so that everything there does not become smoky from smoke.

Cellar in the house

A small living space forces you to make the most of all the space. Therefore, people often have to build a cellar directly in the house. Yes, it's not the best convenient option, but nothing can be done.

In such a situation, finding the answer to the question of how to dry the cellar in the house becomes problematic, because you cannot use a brazier there - all the walls will become smoked. The option using a candle is not so simple, but heat gun Not everyone can find it.

So, how to dry the cellar in the house, if there is such a need? According to tradition, before starting the whole action, everything should be taken out of the cellar. Then dry all the walls, best using electric heating devices (a regular heater is quite suitable). After this, all surfaces must be treated with an antibacterial and fungal agent and the basement waterproofing must be improved to prevent such cases.

Expensive drying method

Many people believe that it is easier to pay money than to do the work themselves. They came up with a special way to dry the basement - using injections. This is the most complex and expensive method of all those presented above, which consists of introducing special waterproofing agents into the soil with a pump. These injections are made around the entire perimeter of the cellar and prevent moisture from penetrating into it.

The cellar is undoubtedly one of the most important premises on the farm. Its construction must be carefully thought out. But if, nevertheless, the cellar urgently needs to be dried, then in this case only improving the waterproofing and installing a newer ventilation system will help.

How to effectively dry the cellar from moisture and condensation?

Dampness in the cellar is a huge problem for most summer residents and country residents. As a rule, humidity increases due to poor-quality thermal or waterproofing, as well as due to the large number of vegetables and fruits stored indoors. In some cases, condensation forms due to the lack of a ventilation system. Whatever the reason, a wet cellar is in no way suitable for storing food in it, which will quickly deteriorate if constantly exposed to moisture. That is why moisture needs to be removed and completely get rid of such a phenomenon as condensation. Today we will talk about how to dry the cellar and properly prepare it for planting the harvest.

Carrying out preparatory work

The humidity in the cellar is usually at a fairly high high level, so condensation forms on the walls and ceiling. Preparatory work include complete liberation premises from vegetables stored there since last year (they are no longer suitable for consumption, so it is best to remove them from storage).

In addition, it is recommended to temporarily get rid of wooden elements of the room (racks, pallets, various bins, boxes, shelves, etc.). All wooden structures must be taken outside and then washed with hot water and soapy water. Before further use they must be completely dried.

Before dehumidifying the air in the storage room, all supplies and products should be removed from there.

Quite common and effective method disinfection of wooden storage elements - applying a layer of whitewash with the addition of ordinary copper sulfate. As a rule, ordinary lime is used as whitewash, which can be found for sale in any store. Air humidity and condensation in this case will not affect the wood.

In addition, to protect wooden elements from mold and mildew, it is necessary to apply antiseptic impregnation to them. You can use any composition sold in the store.

The walls and ceiling of the storage facility can also then be whitewashed and dried. Otherwise, due to increased dampness in the room, it will not be possible to preserve the crop in proper form. In the fall, when it rains continuously, it will not be possible to properly dry the cellar, so all work must be carried out in the summer.

How does the storage dry out?

In order to get rid of excess moisture in the cellar, it is not enough to simply open all the ventilation holes and the hatch cover. In the cellar, the air will systematically cool down, and the moisture from it will condense, so it will not be possible to dry the underground room with ordinary ventilation. Air humidity and condensation will not go away even after several days of keeping the storage facility with the hatch open. To dry the cellar before the seasonal crop planting, more radical methods should be used.

There are several most common ways to dry a room. Air humidity and condensation are big problem, but with forced drying it’s easy enough to get rid of them.

So, you can remove excess dampness, humidity and condensation in the following ways:

  • Drying a cellar or vegetable storage using an iron stove.
  • Drying the basement using a broiler.
  • Using the most ordinary candles, which will improve natural air draft.
  • Use of special dehumidifiers.

It should be noted that heating the storage facility using an iron stove is an extremely labor-intensive and troublesome task, so it is recommended to abandon this method immediately. And not everyone has the opportunity to install such a stove in storage. It is better to use the remaining three methods, since it is important to dry the cellar quickly and without unnecessary hassle.

Quick drying using a broiler

You can remove excess air humidity and condensation from the cellar using the simplest fryer. This device is not large sizes(portable) is available in almost any country farm. In any case, you can ask your neighbors.

The fryer quickly heats the air in the room.

Before drying the cellar using a roasting pan, it is necessary to partially get rid of excess dampness by natural drying for several days. In this case, the fryer will only “finish off” the remaining dampness, humidity and condensation.

If you haven’t found a suitable device for drying or a roasting pan, then you can make it yourself from the simplest old bucket.

The drying process itself is as follows:

  • Before starting drying, open all the holes that go into the cellar (manhole, ventilation pipes).
  • Next, we lower our brazier (bucket) to the bottom of the storage. You can do this yourself or use a rope and hook.
  • Light a fire in the brazier. It needs to be maintained for some time until the damp air completely leaves the room.
  • According to the laws of physics, warm and dry air from the bottom of the cellar will begin to gradually rise, displacing damp air into open holes. After some time, the cellar will dry completely.

The principle of drying a basement using a roasting pan from an ordinary bucket.

Before drying the cellar using this method, it is necessary to consider some nuances:

  1. It is recommended to use sawdust and wood chips to light the Dutch oven. Once the fire is hot, you can add larger wood to the roasting pan. It is important that the ignition of the brazier occurs before you lower it to the bottom of the cellar.
  2. The heat from the fire will quickly warm up the room, removing the damp air outside. In turn, dry air will quickly spread throughout the cellar. It is necessary that the entire room is saturated with smoke. This will get rid of any biological activity in the storage, which also negatively affects the storage of vegetables and fruits. The effect of warming the air in this case will last for a long time.

However, condensation in the cellar does not always disappear immediately after drying, so you need to wait a little and, if necessary, repeat the action, and also check the quality of the ventilation system.

Drying the cellar with a candle

If you don't want to bother with a Dutch oven, there is an easier way to keep your cellar dry and free of moisture. For this you will need a very ordinary candle.

The candle must be placed under the exhaust pipe.

A lit candle placed under the exhaust duct will increase air draft and also help get rid of dampness. Drying the cellar with a candle will take much longer than with a brazier, but if you have nowhere to rush, then you can use this method without any problems.

When using the candle drying method, it is necessary to increase the length of the ventilation pipe (supply pipe if two pipes are used). This should definitely be done. Next, a lit candle is installed directly under the inlet of the exhaust pipe. It is best to place the candle in a small container (for example, a jar).

To give a certain impulse, which will become the beginning of air draft, it is necessary to set fire to a paper sheet in the exhaust pipe. Further, the draft will be supported by the candle flame.

It was already noted above that this is a slow drying method and can be used if you have enough time. All work on drying the cellar is best done a few days before harvesting, so that the room has time to warm up, dry out and get rid of all biological activity. Using a lit candle, you can dry the cellar in 3-4 days. During this time you will have to change several spark plugs.

If the cellar is large, then it will not be possible to get rid of dampness and humidity with a candle.

Air dryers

Since it is difficult to dry a large cellar using improvised means, special dehumidifiers are used to effectively get rid of moisture. These devices allow you to efficiently dry the room, and then maintain the humidity level at a normal level. It is advisable to periodically dry the air in the cellar.

Appearance and operation diagram of the air dryer.

Dehumidifiers are especially relevant for the commercial operation of basements and vegetable stores. Modern dehumidifiers are sold in large construction stores, as well as in specialized departments, so there will be no problems with their purchase. About how to dry a cellar using a dehumidifier, it is best to ask a sales consultant who can recommend a model suitable for your room.

The principle of drying stagnant and damp air in a basement is that moisture always condenses on cold surfaces. The air passing through a conventional dehumidifier is cooled, and the moisture settles in a special receiver, after which it drips into the pan. Dehumidifiers work on the principle of cooling the air rather than heating it (unlike a broiler or candle), so the device will cool the cellar to some extent. However, you can find devices on sale that will heat the air at the outlet to the original temperature.

Modern dehumidifiers operate on the basis of freon (as do refrigerators and air conditioners). Air will be drawn into the dehumidifier using a fan. If your home also has humid air, then a basement dehumidifier is quite suitable for use in other areas of the building.

Which method should you choose?

You can make the cellar absolutely dry and suitable for storing fruits and vegetables using any of the proposed methods. You should choose one method or another based on the total area of ​​your cellar. For example, there is no need to buy an expensive dehumidifier if your cellar area does not exceed 2 square meters. m. In this case, the problem of humidity can be easily solved with the help of a brazier or a candle.

You can put fruits and vegetables into the cellar immediately after all work on drying the room has been completed. It is worth noting that it is not recommended to dry the cellar additionally during operation. This approach will negatively affect the quality of stored vegetables.

To avoid the need to frequently dry the cellar, it is necessary to provide in advance for the presence of a high-quality ventilation system. For small cellars, a design consisting of two pipes (supply and exhaust), located at different heights, is quite suitable. They will ensure continuous air replacement. If the cellar has a large area, then a device is recommended forced ventilation. In addition, if the ceiling of the cellar is the floor of a living space, you will need to make high-quality thermal insulation of the ceiling. It must not be allowed to cold air from the storage affected the microclimate in the house.

Tips and effective ways to dry a cellar in a garage

Garage owners sometimes face the problem of high humidity in the cellar built there. This affects the properties of the metal and the storage conditions of the products. Sometimes such situations arise at certain times of the year. But it also happens that the appearance of water is associated with omissions in construction work. Regardless of the reason for the appearance of condensation, the question arises - how to dry the cellar by removing condensation and dampness.

Prevention Methods

In order not to encounter moisture in the cellar, it is worth considering the following conditions when designing the room:

  • When choosing wall materials, preference should be given to hydrophobic materials characterized by poor water conduction properties. Such materials include concrete grade M 400 and higher. You can also use additives in plain concrete to increase its water-repellent qualities.
  • The use of external waterproofing prevents the penetration of groundwater from the outside.
  • Installing a blind area around the garage will drain water resulting from rain or melting snow.
  • Ventilation pipes should be located in the cellar. The channel for air flow should be almost at the height of the floor (more than 10 cm). The exhaust pipe is located under the ceiling surface (10 cm below). Equipping the outside of the pipes with an umbrella will prevent precipitation from getting inside the cellar. To create a large traction force, the air ducts should be made in a straight shape. If it is not possible to install pipes in a straight position, the side outlet is located at an angle of at least 60° with respect to the horizon. The slope should have a length of no more than 100 cm.
  • Having a vapor barrier between the basement and the room above will prevent moisture from entering.
  • If there is an earthen floor, the penetration of moisture into the cellar increases. When compacting and covering the floor with plastic film, humidity levels are reduced. Installing a concrete floor with waterproofing will protect against condensation.
  • The presence of waterproofing and vapor barrier of the walls will reduce the hygroscopicity of the material. External insulation is carried out by coating the outer sides with mastic. Cement-based compounds are used for internal insulation.

Drying a ventilated basement

Before draining your basement, you should do some preparation. To do this you will need lime and copper sulfate. After removing all the shelves and drawers, you need to check for the presence of mold deposits. If they are available, then wooden surfaces are treated with copper sulfate dissolved in water. The concentration of the solution is 5-10%.

The area inside the cellar is whitewashed with lime. Take a thick mixture of limestone with an admixture of copper sulfate (5-10%). The corners should be coated well. Spray the surfaces in the room with a brush with a thick solution of whitewash. After the lime has dried, reapply another layer. When the walls are dry, you can dry them.

How to dry a cellar in a garage if at first there was no condensation, but then it appeared. The cause may be clogged air ducts. When cleaning pipes, moisture disappears. But it happens that moisture remains. Then, it is necessary to carry out the process of activating the movement of air masses in the following ways:

  • Install a high power fan on the draft pipe. Open existing hatches and windows. The drying period lasts 3-10 days.
  • Apply heat using a candle. To do this, the air duct for the outflow in the cellar is extended and a burning candle is placed under it. It is possible to use dry alcohol. Under the influence of heat, the pipes dry out and good traction appears.
  • Heating the room using a “brazier”. It can be a bucket with holes or another metal container. Smoldering coals, coke, and coal are placed in the container. Then the bucket is placed in the cellar, the door and windows are closed. Sometimes the doors should be opened slightly to allow fresh air to enter. After the coals go out, you need to re-ignite them. After all the coals have burned out, the bucket is removed. The usual one of these buckets is enough to dry the cellar.

In hot weather, there are situations where increased air movement leads to increased condensation. This is due to the temperature difference between inside and outside the room. In this case, ventilation is not carried out. On the contrary, you need to close all the hatches and windows. After the air temperature drops to +10°, carry out ventilation actions using one of the methods.

You can dry the cellar in winter by using other heaters:

  • Heat gun 3-5 kW;
  • Kirogas;
  • Potbelly stoves;
  • Propane burners.

When using such methods, you need another person for backup.

The process of drying a cellar in the absence of ventilation

In the absence of a ventilation system, some kind of pipes should be installed. You can run the pipe into the wall or ceiling. Another option is to purchase a fan with a supply and exhaust mechanism. A cellar without ventilation is dried using hydrophilic materials:

  • Dry sawdust, the scattering of which helps to reduce humidity levels.
  • Slaked lime, laid out on shelves and along walls, removes moisture and helps destroy fungus.
  • Calcium chloride, which has moisture absorption properties. For 1.5 liters of water, 1 kg of substance is required. After calcination of the wet composition, you can use it again.
  • Dry cardboard boxes used to eliminate condensation on the ceiling.

You can also purchase special equipment - a household dehumidifier.

After flooding, the cellar should first be pumped out. And then take it all out. After drying, with doors and hatches open, whitewash with lime. After this, apply the described methods.

Isolation from moisture using drainage

When insulation is installed during construction, moisture problems disappear. But it happens that moisture still appears. Then external and internal drainage methods are used.

External drainage involves draining water into sewer outlets. External drainage stages:

  • Digging a trench 40-50 cm below the cellar floor level;
  • Wells are made at separate two-meter distances into which the tubes are inserted.
  • Geotextiles are placed in the trench to prevent flooding.
  • Fill the trench with gravel or sand and lay geotextiles on top.
  • Compacting soil over the trench.

Internal drainage is used when draining a large cellar. Drainage stages:

  • Digging trenches indoors about half a meter deep.
  • Geoseptic material is placed at the bottom of the trench.
  • Sprinkling gravel into the trench at a distance of 15-20 cm.
  • Laying drainage pipes maintaining a slope of 3 mm per meter of pipe.
  • Coating pipes with gravel mixture.
  • Laying geotextile material.
  • Filling trenches with sand or earth.
  • Install the block at the lowest point of the floor. You can buy it or make it yourself, providing a hose for draining water.
  • Equip the well with a pump to pump out water.

It is better to equip drainage systems during the construction of the cellar.

Suitable for different cellars when removing moisture different methods. You can use a home-made dehumidifier for the basement or think about removing excess moisture during the construction stage.
