How to effectively dry the cellar from moisture and condensation? Humidity in the basement: causes, consequences and methods of elimination Very high humidity in the cellar

Cellar owners often complain about the humidity in it. Usually this problem is associated with violations made during construction. How to reduce the humidity in the cellar is a question that worries many Russians who store their vegetables in cellars and cellars.

IN basements and cellars often appear excessive moisture. If time does not begin to take measures to eliminate it, then a fungus will appear, and then mold.

For obvious reasons, moisture and dampness are unacceptable in cellars and cellars. In a room with moist air, mold and fungus appear. It is impossible to store vegetables in such a basement, and if a humid room is located in ground floor, this may adversely affect the integrity of the entire structure.

One of the causes of humidity and dampness is moisture that enters the room through the walls and then accumulates on the floor. In the process of its evaporation, the humidity of the air increases many times over.

If the cellar or basement is located in a private house, the cause of dampness may be insufficient insulation of the building. At low temperatures, water penetrates through the joints in the walls of the house into the basement.

Groundwater may also be the cause. This is possible with poor waterproofing of the floor.

Moisture removal methods

You can reduce the humidity in the basement different ways. But first, check the condition of the basement waterproofing. If it does not cope with the task, then it must be redone. This is often not the cheapest option.

Most inexpensive way, at which the moisture in the cellar can be removed, is as follows:

  • purchase polyethylene film, you can use the old one, the main thing is that it be whole. Also you will need shovel, trowel and clay. If the floor of your cellar is clay, then use it;
  • remove a 5 cm layer of clay floor, level and tamp the resulting surface. On top of it, carefully lay two layers of polyethylene. Pour a clay layer on it and carefully tamp it down as well. This must be done carefully so that the film layer does not move. The clay will begin to dry out and the air in the cellar will become drier. Instead of a clay floor, you can make it out of concrete.

Additional Causes of Humidity

  1. Often moisture in the cellars appears during the snowmelt season and after precipitation. Pour a layer of sand at the bottom of the cellar, and 10 cm of fine gravel on top. The dampness should be gone. If this does not happen within a year, then make the gravel layer thicker by another 10 cm. Groundwater will sink to a lower level, and from there it will no longer be able to rise to the level of the basement or cellar floor.
  2. The humidity in the basement is significantly affected by the condensate that appears on the walls. You can fight it with the help of a special waterproofing plaster. Plaster the walls of the basement with it - and they will begin to breathe. Condensation will disappear along with dampness. Ready-made waterproofing mixture is sold in stores. You can cook it yourself. Add a waterproofing additive to dry plaster.
  3. Remove fungus and mold from the walls with a special solution and apply plaster to the wall.
  4. Moisture in the cellars appears where thin and cold floors are made in them. Make a double floor, in the middle of which lay a layer of roofing material. The humidity in the air will decrease.
  5. You can fight moisture in the basement with the help of potassium chloride, which quickly absorbs excess moisture. Pour the powder of this substance into jars and place it in the corners of the cellar. This method works well if you have a small cellar.

What to do if nothing helps

If all these simple ways cannot reduce the humidity in the cellar, then additional waterproofing must be created.

  1. Start by waterproofing the floor. Cover it with several layers of bitumen. Heat it up with a building hair dryer and lay two layers of roofing material on top. Instead, you can lay waterproofing, it is not exposed to rot and is resistant to mold.
  2. At the second stage of waterproofing, build additional walls in half a brick. Between them you mount a waterproofing layer. On top of the cellar do concrete screed at 10 cm.

Has moisture started to appear on the floor and walls in the basement? What should be done to make it dry and suitable for storing vegetables?

  1. The first thing you need to do is ventilate the basement regularly by opening it every day. Check ventilation.
  2. If moisture appears on the walls and floor in the basement in the spring, they must be repaired. On the floor, make a screed of waterproof cement. Carefully inspect the walls, if they have cracks, repair them, and then plaster the walls.
  3. If possible, dig out the basement walls from the outside. Repair any cracks you find. cement mortar. Cover the walls with a layer of bitumen or roofing felt, this will enhance the waterproofing of the basement. You can make a clay castle around its perimeter. In the trench around the basement, lay the clay in layers of 20 cm, carefully tamping. Such a lock will completely block the flow of groundwater and rainwater to the basement walls.
  4. You can additionally along the outer perimeter of the basement, in a trench dug to the depth of the foundation, lay drainage pipes through which water will be discharged into drain hole or septic.

Is groundwater flooding the basement floor? Dig a hole below the basement floor level. Make a gravel pillow in it, place a container on it with holes drilled in the side walls.

The container must be wrapped with a cloth that passes water well, it will prevent the holes in the container from silting up. Place a float pump in it. Water fills the tank, the float rises and turns on the pump. The water is pumped out, the float drops and the pump turns off. Such a device will allow you to effectively deal with water and humidity in the basement.

Many homeowners have underground storage facilities for various items and agricultural products, which deteriorate quickly in a humid environment. However, if there is a very damp basement below - what to do in this case?

First of all, the causes of this phenomenon should be determined, because further actions will depend on them.

First, I would like to consider simple recommendations that help get rid of this negative effect with low humidity. In other cases, it will be necessary to carry out a series complex work on the qualitative organization of the main systems.

  • One of the simplest ways is to install containers filled with powder. white moss . This adsorbent will absorb moisture from the room air.
  • If dampness has led to mold in many places, then it is better to treat with hydrochloric acid, but this will require freeing the interior from products. In the process of work, a weak solution is used, with which the walls are washed.
  • Also, damp walls in the basement can be dried using ceramic bricks heated to high temperature. As it cools, the material will begin to absorb excess moisture.

Addition!
You can also get rid of dampness with the help of slaked lime by placing a wooden or metal container with a small amount of substance in the corner.
Gradually, the air will dry out.

Technological methods

These include the device systems, the creation of which requires certain knowledge and skills, but with the proper approach, the work can be done by hand. Knowing the basics installation work, you can correctly organize the above structures in the basement.

Waterproofing device

The formation of a barrier against moisture from the outside of the underground room is important point, since in the presence of closely spaced ground water dampness cannot be eliminated in other ways.

There are quite a lot of materials for creating waterproofing, but in this case we will talk about bituminous mastic, which belongs to coating analogues.

  1. Initially, special fillets are made at the intersections of the planes, due to which there will be no mating between the surfaces located at the corners.
  2. Using a fine-grained cement-based composition, various depressions are overwritten, otherwise small bubbles may remain after applying the mastic.
  3. Further, the remains of construction debris, dust and dirt are removed from the lower base. If the concrete is excessively wet, then it dries out, then it will be possible to avoid violations of the waterproofing layer.
  4. For high-quality adhesion to the surface, the lower part is primed. The process uses specific grades of bitumen with solvents that can evaporate quickly (for example, with kerosene or gasoline).
  5. After the preliminary layer of the primer has dried, the mastic is applied directly to the surface. Work is carried out using a brush, spatula or conventional roller.
  6. In the areas of adjunctions to the walls, reinforcement is made with fiberglass materials, which are placed in the starting layer of processing. This is necessary to protect against cracks and other defects.

Note!
Application bituminous mastic carried out in 2-4 layers, but it all depends on the operating conditions of the basement and external factors(groundwater occurrence, atmospheric precipitation, and so on).

Creation of ventilation

So, if there is strong dampness in the basement - what else to do? Now you need to properly organize another system, without which even when humidity can be maintained, because air flows must move correctly.

Moreover, since forced system needs additional energy resources and costs.

  1. The diameter of the pipes is pre-selected after simple mathematical calculations. An opening of approximately 26 square centimeters is required per meter of area.
  2. Then the exhaust pipe is mounted, the upper part of which is displayed on the roof. Most often, it is located with a fireplace and stove smoke channel, since in this case the air draft improves.
  3. The supply air duct is installed in the opposite corner of the room, while it must be at least 50 cm from the floor. It is also displayed on the roof, but rises to a lower height.
  4. On last step testing is carried out, for which an ordinary match is lit. In the case of normal air intake, it will burn evenly. If a trembling flame is observed, then you will have to shorten the supply channel and adjust the height of the hood.

Structure of forced air exchange for comparison.

Dampness in the cellar is a huge problem for most summer residents and suburban residents. As a rule, humidity rises due to poorly made heat or waterproofing, as well as due to a large number 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, with constant exposure to moisture, will quickly deteriorate. That is why moisture must be removed and completely eliminated from such a phenomenon as condensate. We will talk today about how to dry the cellar and properly prepare it for laying the crop.

Carrying out preparatory work

Humidity in the cellar, as a rule, is at a high enough level, so condensation forms on the walls and ceiling. Preparatory work include complete release 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 the wooden elements of the room (racks, pallets, various bins, boxes, shelves, etc.). All wooden structures take it outside and then rinse hot water And soapy water. Before further use they must be completely dry.

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

A fairly common and effective method of disinfecting the wooden elements of the storage is to apply a layer of whitewash with the addition of ordinary blue vitriol. As a whitewash, as a rule, ordinary lime acts, which can be found on sale in any store. Humidity and condensation in this case will not affect the wood.

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

The walls and ceiling of the vault can also be whitewashed and dried later. Otherwise, due to increased dampness indoors, it will not be possible to keep the crop in the proper form. In the fall, when it rains continuously, it will not be possible to dry the cellar efficiently, so all work should be carried out in the summer.

How is storage drying?

In order to get rid of excess moisture in the cellar, it's not enough just to open everything ventilation holes and manhole cover. In the cellar, the air will systematically cool down, and the moisture from it will condense, so it will not work to dry the underground room with ordinary ventilation. Humidity and condensate, even after several days of keeping the storage with the hatch open, will not go anywhere. To dry the cellar before the seasonal laying of the crop, more radical methods should be used.

There are several of the most common ways in which the drying of the room is carried out. Humidity and condensation are big problem, but with forced drying, it is quite easy to get rid of them.

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

  • Drying the cellar or vegetable store with iron stove.
  • Drying the basement using a brazier.
  • The use of the most common candles, which will improve the natural draft of air.
  • The use of special dehumidifiers.

It should be noted that heating the storage with an iron stove is extremely time-consuming and troublesome, 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.

Fast drying with a roaster

You can remove excess air humidity and condensate from the cellar using the simplest brazier. This device is not large sizes(portable) is in almost any suburban economy. In any case, you can ask your neighbors.

The brazier quickly heats up the air in the room.

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

If you did not find a suitable device for drying or a brazier, then you can make it yourself from the simplest old bucket.

The drying process itself is as follows:

  • Before drying, we open all the holes that go to the cellar (manhole, ventilation pipes).
  • Next, we lower our brazier (bucket) to the bottom of the storage. You can do it yourself or with a rope and a hook.
  • We kindle a fire in the brazier. It must 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 gradually rise, displacing damp air into open holes. After some time, the cellar will dry out completely.

The principle of drying the basement using a brazier from an ordinary bucket.

Before drying the cellar in this way, it is necessary to provide for some nuances:

  1. To ignite the brazier, it is recommended to use sawdust and chips. As soon as the fire breaks out, larger wood can be thrown into the brazier. It is important that the brazier is ignited before you lower it to the bottom of the cellar.
  2. The heat from the fire will quickly warm up the room, bringing damp air out. In turn, dry air will quickly spread through the cellar. It is necessary that the whole 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 heating the air in this case will persist for a long time.

However, the condensate in the cellar does not always disappear immediately after drying, so you need to wait a bit and, if necessary, repeat the event, as well as check the quality of the ventilation system.

Drying the cellar with a candle

If you don't feel like messing around with the brazier, there's an easier way to keep your cellar dry and damp. To do this, you need the most ordinary candle.

The candle must be placed under the exhaust pipe.

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

When using the candle drying method, it is required to increase the length of the ventilation pipe (inlet if two pipes are used). This must be done. Further, a lit candle is installed directly under the inlet of the exhaust pipe. The candle is best placed in a small container (for example, in a jar).

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

It has already been noted above that this is a slow drying method and it 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. With the help of a lit candle, you can dry the cellar in 3-4 days. During this time, you will have to change a few candles.

If the cellar is large, then getting rid of dampness and humidity with a candle will not work.

Air dryers

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

Appearance and scheme of operation of the dehumidifier.

Dehumidifiers are especially relevant in 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. For information on how to dry a cellar with a dehumidifier, it is best to ask a sales assistant who will be able to advise a model suitable for your room.

The principle of drying stagnant and damp air in the 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 drops into a drip tray. Dehumidifiers work on the principle of cooling the air, not heating it (unlike a brazier and a candle), so the appliance will cool the cellar to some extent. However, on sale you can find such devices that at the outlet will heat the air to its original temperature.

Modern dehumidifiers work on the basis of freon (like refrigerators and air conditioners). The air will enter the dehumidifier with the help of a fan. If your home also has humid air, then a basement dehumidifier is fine for use in other areas of the building as well.

Which method to 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 or another method based on the total area of ​​\u200b\u200byour cellar. For example, there is no need to buy an expensive dehumidifier if your cellar does not exceed 2 square meters. m. In this case, the problem of humidity is easily solved with the help of a brazier or a candle.

It will be possible to lower fruits and vegetables into the cellar immediately after all work on drying the premises is completed. It should be noted that it is not recommended to dry the cellar additionally during operation. This approach will negatively affect the quality of stored vegetables.

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

Dampness in the basement is an unpleasant phenomenon. What to do if it appears? Before you begin to deal with the problem, you need to find out the cause of the appearance of moisture in the house. Understanding the cause will help you choose effective methods and for a long time, and maybe forever get rid of such a nuisance as wet surfaces in the room.

Why is dampness dangerous?

Why is it necessary to remove excess moisture from the premises? The appearance of moisture in the basement can lead to unpleasant phenomena that are difficult to get rid of.. Condensation on surfaces causes the following effects:

  • the appearance of mold and fungus;
  • violation of the temperature and humidity conditions of the premises;
  • violation of operating conditions building structures, which leads to destruction in the foundation and other load-bearing elements;
  • the appearance in the premises of various microorganisms that are dangerous to humans and lead to serious diseases;
  • wetting of walls and ceilings, violation of interior decoration.

Causes of the problem

Mold in the basement appears as a result of dampness

There are several reasons why condensation may occur on the ceiling, floor and walls of the basement:

  1. Basement ventilation problems. This can be caused by errors at the design or construction stage. Sometimes it happens that provided for by the norms ventilation ducts cut by improperly laid floor slabs or clogged with construction waste. The lack of normal ventilation leads to the fact that during cold weather, condensation forms in the basement, which is warm compared to the outside air, and the windows sweat.
  2. Change in groundwater level. This problem is especially relevant in spring period when the snow begins to actively melt, and the soil is oversaturated with moisture. The issue must be taken into account at the design stage and provide for a drainage system and reliable waterproofing basement. An increase in water in the soil leads to the fact that puddles appear on the floor. Their depth depends on the extent of the problem.
  3. Why does such a phenomenon occur? The answer to the question will be - a violation of the foundation construction technology. If during construction no attention was paid to the vertical waterproofing of the basement walls, then during operation they inside drops of moisture will appear.

Scheme of improper organization of ventilation

Groundwater in the basement - the cause of dampness in the basement

Capillary penetration of moisture from the soil - the cause of dampness in the basement

All these reasons why dampness appears in the basement are associated with the neglect of technology at the construction stage of the building.

Ways to fight

To understand what to do with dampness, it is necessary to correctly determine the reason why surfaces get wet. Further actions aimed at getting rid of excess moisture depend on its source. The cause can be determined by the location of the moisture.

  • if droplets form on the ceiling and walls - the reason is insufficient ventilation;
  • the formation of liquid drops only on the walls - the lack of vertical waterproofing of the basement walls;
  • in the presence of puddles on the floor - the reason is flooding with groundwater.

Further steps are taken depending on the source of the problem.

Insufficient ventilation

If condensation has formed due to insufficient air exchange in the room, it can be removed by organizing additional ventilation. The same situation is relevant for the occurrence of dampness in the attic. This room also heats up, but at the same time it is in direct contact with the external environment.


Scheme natural ventilation cellars

Contact warm air with cold surfaces - the main and only reason why condensation forms. With sufficient air exchange in the basement or in the attic of the house, heated from interior spaces the air is cooled. Condensation does not form.

Ventilation in the basement of a private house or in the attic can be done in two ways:

  • natural;
  • forced.

Natural includes air and ventilation ducts. According to the norms, the total area of ​​​​the vents must be at least one four hundredth of the area of ​​\u200b\u200bthe room. Forced means the use of special equipment, the installation of which will require serious financial costs. The method is relevant only for large rooms.

To remove condensation on the ceiling and walls in the basement or in the attic, you must perform the following measures:


Scheme of forced ventilation in the cellar
  1. thermal insulation engineering networks . The basement has plumbing and sewer pipes, the temperature of the liquid in which is higher than in the room. This causes condensation to form on their surface. To get rid of heat losses, it is necessary to make reliable thermal insulation protection for pipes that sweat precisely because of heat leakage into a cold space. Thermal insulation measures can be performed using special materials. Manufacturers mineral wool, polystyrene and extruded polystyrene foam produce special products that are convenient to put on pipes. Efficient materials allow you to remove heat leaks and get rid of the reason why the pipes sweat.
  2. To eliminate dampness in the attic or in the basement of the house and the appearance of drops of moisture on the ceiling or walls, ventilation ducts or pipes are installed. After the construction of the house is completed, it is not possible to place ventilation ducts in the walls, so they are attached to vertical structures. To get rid of dampness on the ceiling and other surfaces, two pipes are provided in the room - supply and exhaust. They need to be done in different corners of the room, located at different heights from the floor.

After the reason why condensation appears in the attic or basement has been eliminated, the room is dehumidified.

Insufficient waterproofing

If the walls of the basement of the house (without a ceiling) are sweating, the reason is capillary moisture. You can get rid of it in one of the following ways:

  1. Pasting waterproofing materials. They are presented on the construction market mainly by roofing material, linochrome and hydroisol. They are made on the basis of a canvas impregnated with bitumen. The gluing process is a rather labor-intensive undertaking. It is better to entrust such work to professionals.
  2. You can protect the walls of the basement from moisture at home using bituminous mastic. In addition to it, polymer compositions and synthetic resins are used. The advantage of the method is the ability to do the work with your own hands. Minus - insufficient degree of protection. It is usually used together with pasting materials.
  3. penetrating compounds. In order to get rid of capillary moisture, you can use compounds that penetrate concrete and increase its moisture resistance. The action is achieved by narrowing the pores in the structure. This method can be called highly effective, since not only the premises are protected, but also part of the supporting structure. The composition is able to penetrate to a greater thickness and prevent water damage to the foundation for many years.
  4. Screens. This method is suitable for high pressure groundwater. Clay castle, geotextile or betonite become screens.

Work with any material is performed in the following sequence:

  • removal of finishes from the walls, their cleaning;
  • surface treatment with an antiseptic;
  • primer;
  • waterproofing walls and floors;
  • finishing;
  • a blind area around the perimeter of the building, if it is missing or damaged.
  • draining the basement space.

Groundwater level rise

Wet walls from behind high level water in the soil is the most serious problem for the home of the presented. If the condensate does not require external measures, then in this case it is necessary to dig out the foundations. It is recommended to make waterproofing in the following order:

  • excavation of the foundation;
  • drainage device around the perimeter of the building;
  • if necessary, strengthening the foundation;
  • performance outdoor waterproofing(use the same materials as in the previous case);
  • performance of internal waterproofing;
  • backfilling;
  • blind area around the perimeter of the building;
  • dehumidification of the room.

Scheme of the construction of the basement waterproofing structure at a high pressure of the groundwater level

The method will require impressive financial and labor costs, but it will protect the foundations and basement from groundwater. The material is selected depending on the pressure of the water. Several methods can be used together, for example, penetrating compounds along with pasting waterproofing.


Any living space requires maintaining an optimal level of humidity. Special attention it is necessary to pay attention to the control of the level of humidity in the basements and cellars of garages. To do this, they equip good ventilation and waterproofing. But what to do if the water in the cellar still appeared? In this case, the owners of the garage should immediately take measures to dry the cellar. How to do it right, and what are the ways to dry the cellars from moisture - read our article.

Why does moisture accumulate in the cellar

The main reason for high humidity in the cellar of the garage is poor waterproofing or its complete absence. Due to mistakes made during the construction of a garage with a cellar, moisture gradually begins to accumulate in the room, and condensation appears on the walls. As a result of high humidity, an ugly plaque (fungus) appears on the walls. This phenomenon is unacceptable for cellars in which food is stored, therefore it is important to carry out high-quality drying of the room in a timely manner.

Ways to dry the cellar in the garage

The constant accumulation of moisture in the cellar negatively affects the condition of the entire structure. To dry the cellar in the garage, you can use several methods. The most effective of these are candles and a brazier (metal stove, photo 1).

Important! Before you start drying the cellar, you need to carry out a good audit in it, remove the shelves, take out the interfering equipment and supplies upstairs. When all the debris is removed from it, the room is dried with outside air to remove excess moisture, and then a method is chosen to normalize the humidity level.

There are two most famous ways to deal with excessive moisture in the basement of the garage.

Attention! If there is a lot of water in the basement, then before drying it must be pumped out with a pump, or scooped out manually. It is important to determine what is the source of water in the cellar. Possibly poor insulation. But it may also be that the room was built next to the spring. In this case, you need to divert the water to the side with a pump and equip the cellar with good waterproofing.

Arrangement of waterproofing in a damp basement

In order for the drying of the basement in the garage to be effective, it is necessary to take care of the arrangement of external and internal insulation. You can create it with your own hands, without involving specialists. You can purchase materials for external and internal drainage at a hardware store.

Arrangement external drainage(Scheme 3) in the cellar involves the creation of a system for removing excess moisture outside the premises. It is best to equip the exterior at the construction stage of the garage, but you can perform waterproofing in an already finished room if the humidity level increases greatly. The principle of creating external waterproofing is as follows:

  • A trench is dug along the outer perimeter of the building (it should be 50 cm lower than the floor level in the cellar);
  • Drainages are installed along the entire length of the dug trench in the form of plastic pipes (for them, wells must be prepared in advance to a depth of the first layer of sand). The upper part of the drains must be covered with a metal mesh (this will prevent contamination of the entire system);
  • A geotextile is laid at the bottom of the trench waterproofing material(it should also go to the walls);
  • The finished drainage channel is covered with crushed stone to a height of 40 cm. The crushed stone layer should be larger than the floor line in the cellar;
  • The embankment is well rammed.


Scheme 3

internal drainage(Scheme 4) will dry the cellar much faster. For its arrangement, the following materials are needed: geotextile waterproofing, crushed stone and gravel, drainage pipes, drainage pump, PVC tank, sand. Pipes are laid around the perimeter of the room to collect excess water. The diameter of these pipes can be different, but it is best to choose designs with a diameter of 110 mm. Arrangement of internal drainage system in the basement of the garage is better to do during the construction phase. Otherwise, you will have to dismantle the floor in order to lay all structural elements systems.

Internal drainage in garage cellar laid in accordance with the following scheme:

  • They dig a trench about 50 cm deep around the entire perimeter of the room;
  • The bottom is well tamped, then a geoseptic is laid on it (this material perfectly absorbs moisture, thereby performing the function of waterproofing);
  • A layer of fine-grained material (gravel, crushed stone) 20 cm thick is laid in the trench;
  • Pipes are laid on top of the embankment, maintaining an angle of inclination of 3 mm;
  • A layer of gravel is again poured over the laid pipes, but already of an average fraction. The material is well rammed and a layer of geotextile is laid on it;
  • The final action in this case will be backfilling the trench with sand and soil (taken out during digging), careful tamping.


Scheme 4

There is another method for effectively drying the cellar in the basement - injection protection(scheme 5). This method is one of the most expensive, but at the same time it is the most effective. When using this method, the waterproofing in the cellar is equipped using injections. Naturally, specialized equipment is required to perform such work. The injection drying method is recommended for garages built of concrete, brick and foam blocks. The injection drying technology looks like this:

  • Around the perimeter damp basement holes are drilled with a diameter of 1.5 to 4 mm. A distance of 20-80 cm must be observed between adjacent holes. In each case, the parameter will be different and depend on the level of humidity, wall thickness and soil characteristics;
  • Special elements are inserted into the prepared holes, through which the pump is injected liquid waterproofing or polymers;
  • The advantages of such waterproofing are obvious. There is no need to dismantle the cladding from the walls, breakage of building structures. In addition, work on the arrangement of waterproofing in this way can be carried out in any weather, at any time of the year.
