How to remove excess moisture from the basement. How to effectively dry the cellar from moisture and condensation? How to strengthen a thin floor in the cellar

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 the operating conditions of 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:

Basement ventilation problems. This can be caused by errors at the design or construction stage. Sometimes it happens that the ventilation ducts provided for by the norms are cut by incorrectly laid floor slabs or clogged with construction debris. 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.
Change in groundwater level. This problem is especially relevant in the spring, when the snow begins to melt actively, 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 of the 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.
Why does such a phenomenon occur? The answer to the question will be - a violation of the foundation construction technology. If during construction attention is not paid to the vertical waterproofing of the basement walls, then during operation, moisture droplets will appear on them from the inside.

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 of natural ventilation of the cellar

The contact of warm air with cold surfaces is the main and only reason why condensation forms. With sufficient air exchange in the basement or in the attic of the house, the air heated from the interior 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

Thermal insulation of engineering networks. In the basement there are water 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 of mineral wool, polystyrene foam 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.
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:

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.
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.
penetrating compounds. 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.
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 due to high water levels in the soil is the most serious problem for a house 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 of external waterproofing (the same materials are used 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.

Dampness in the cellar is a serious problem, as it quickly leads to the formation

If preservation or food stocks (potatoes, onions, pumpkin, beets) are stored in the room, this will lead to their deterioration.

Therefore, everyone should know a couple of simple rules on how to get rid of dampness in the cellar using folk methods or the latest advances in technology.

Causes of dampness

Dampness in a room is usually referred to as the accumulation of moisture in the form of condensation on the walls and ceiling. It manifests itself by blackening of the corners and the formation of mold on the walls, the appearance of an unpleasant smell in the room. You need not only to know how to remove dampness in the basement, but also to understand why it is formed in order to deal with the cause, and not the effect, in the first place. The provoking factors for the formation of excess moisture in the cellar are:

A lot of trouble causes condensate in the basement, which settles on the walls and ceiling in the form of dew. This happens as a result of the temperature difference between the street and indoors. The walls in the winter freeze through, so under the influence of heat from the inside, dew forms.

In the summer, everything happens exactly the opposite, dew forms on surfaces due to the ingress of warm air from outside. In the off-season, the basement is rarely damp.

Do I need to deal with moisture

Not everyone is looking for ways to dry the cellar in a garage or house, believing that mold and high humidity in such a room are the norm. But a dry and dark basement is considered the norm, it is in it that you can store supplies for the winter and vegetables for eating without fear for your health. The indoor humidity is measured using a hygrometer. The indicator should always be at the level of 85-95%.

You can check the level of moisture accumulation even with a simple glass of water. To do this, you need to put it in the refrigerator for a day, and then put it in the basement. If, under the influence of heat, drops formed and dried quickly, the humidity in the room is too low, if they turned into large drops and glass in small streams, then we can talk about high humidity. Normally, the walls simply remain misted.

Excessive accumulation of moisture affects the air in the room, making it heavy and unpleasant, and also threatens with the following troubles:

Spoilage of all food and things that are stored indoors.
The appearance of mold and fungal formations that can cause respiratory diseases even with a short stay in the room.
Destruction of walls, finishing material, decrease in the stability of the load-bearing structures of the basement floor of the building. This usually leads to the need for costly repairs.

To prevent such negative consequences, you should adopt a few simple ways to dry the garage from dampness, or the basement if moisture has begun to accumulate in it.

Ways to deal with high humidity

The fight against excess moisture in the cellar should begin by establishing the cause. This allows you to take the right measures to improve the microclimate in the basement, garage or cellar. Today on the market you can find a lot of modern means for waterproofing, as well as suppressing the growth of mold. However, they themselves are ineffective without the arrangement of high-quality ventilation and a water drainage system.

Better ventilation

Proper air circulation in the basement is the key to dryness in the room and the absence of fungus. The ventilation system consists of supply and exhaust. For each of them there are requirements for placement:

So that the ventilation shafts do not freeze over in the winter, they are insulated, and also supplied with valves and condensate collectors. With their help, you can regulate the flow of air if it is freezing outside.

The cross section of pipes for ventilation is selected based on the volume of the room. If the shafts are already installed narrower than required, a small fan can easily correct the situation. If the device is equipped with humidity sensors, then they turn on automatically.

Lower groundwater

The problem of dampness is especially acute if the cause of its formation is the penetration of groundwater into the premises. Since this often causes premature destruction of the structure. To prevent this from happening, a number of measures are being taken to strengthen the foundation and pump out groundwater. They are as follows:

The foundation is dug around the perimeter. The depth should be approximately 20-30cm.
Drainage is organized along the formed perimeter.
The base is strengthened, external and internal waterproofing is installed.
The room is thoroughly dried.

It is quite difficult to independently carry out the entire complex for the removal of groundwater. Therefore, it is much easier to attract specialists for this, who will carry out all the actions efficiently and quickly. Usually their services are cheaper than correcting all the mistakes made in the process of arranging by amateurs.

Elimination of capillary moisture

If heavy drops are constantly collected on the walls, then this indicates the penetration of liquid from the outside. You can exclude its hit by one of the popular methods:

The latter option is especially relevant if groundwater enters the room along with capillary moisture. Also, builders often use pieces of dense material impregnated with bitumen, linoleum, waterproofing or roofing material as insulation. Compositions can only process problem areas from which moisture oozes, or entire walls.

Arrangement of external waterproofing

If moisture gets inside the room due to the poor condition of the external waterproofing, then first of all it is necessary to inspect the house for “weak spots”. Particular attention is paid to the blind area, drainage system, downpipes, slopes. It is necessary to pay attention to their condition and functionality. If the drainage system, it is necessary to make a comprehensive installation of slopes and downpipes. After that, proceed to the protection of the outer walls:

The old blind area is removed.
A pit is made about 50 cm wide, if you count from the outer wall of the cellar.
The wall is thoroughly dried (it is better to do this in good weather).
A waterproofing antifungal composition is applied.
The wall is coated with bituminous mastic, clay or concrete with liquid glass additive.
A blind area is made of roofing material (the sheet is fixed 0.5 m above the ground level and is displayed beyond the edge of the outer wall of the basement).
Yama falls asleep.

It is best to do external insulation along with the drainage system. After the work done, they begin to dry the basement and arrange the internal waterproofing, in the process they use a building material with a low ability to pass moisture.

Prevention of condensation

Preventing the formation of heavy drops on the walls is much easier than dealing with the problem from time to time, resorting to radical methods. Therefore, every basement owner should know a few simple ways to avoid dampness in the basement:

It is necessary to take care in the repair process not only of the basement, but also of the rooms located above it. To prevent the penetration of moisture, a high-quality vapor barrier is arranged between them.

High humidity and dampness in storage areas and basements lead to the formation of rot, fungus and mold. The walls turn black and begin to crumble. Products spoil. There is a risk of infection entering other rooms and harming the health of residents of the house. You need to know how to dry the cellar so that you can use it efficiently and effectively in the future.

Signs and causes of high humidity in underground storage

You can check the humidity level with a hygrometer. In this case, the limiting parameter for basement-type premises will be from 85 to 95%. If this figure increases, then visual signs immediately appear: condensation accumulates in the basement on the walls and ceiling in the form of drops or even flows in streams, the air becomes heavy and stale.

The condensate in the cellar, together with the reduced constant temperature, becomes a medium for the development of various pathogenic organisms such as fungus and mold. If you do not respond in time and do not remove dampness in the basement, it will spread throughout the house through walls and ceilings, and for this you need to understand the reason for its appearance:

improperly designed ventilation system that is not able to remove excess moisture to the outside;
proximity of groundwater to the floor line, aggravated by poor insulation;
lack of vapor barrier in the ceiling;
poor insulation of the walls and ceiling, which leads to sudden temperature changes on adjacent surfaces and the deposition of moisture in the form of condensate.

How to get rid of high humidity in the cellar and basement?

There are several methods to make the cellar dry once and for all. To do this, you need to properly design and install the following systems:

Ventilation. It is necessary to bring 2 pipes with a diameter of at least 125 mm into the room. One - closer to the floor level to ensure the flow of fresh air. The other is near the ceiling, so that it is possible to completely remove excess moisture. The movement of air masses occurs under the action of natural draft force or by means of injection by built-in fans.
External waterproofing. The design is designed to block the access of groundwater inside the walls. First, a trench about 50 cm wide is dug for the entire depth of the foundation. The outer surface of the walls is finished with roofing material glued with bituminous mastic. Adjacent edges overlap each other, providing reliable protection around the entire perimeter. Then they install drainage and fill the free space with soil. At the end, you need to mount a blind area up to 70 cm wide to prevent precipitation from penetrating into the space near the walls.
Internal waterproofing. With a deep location of the premises underground, it is not possible to equip a high-quality exterior finish with insulating materials. In such cases, all work is carried out inside the cellar. To begin with, cracks and potholes are eliminated, the entire surface is covered with liquid, roll or sheet insulating materials. Then the cellar should be completely dry. The floor requires more careful processing. It is covered with sand and expanded clay, a layer of roofing material is laid with gluing the edges with bitumen and a platform is equipped with wooden shields.
Thermal insulation. Before proceeding with the installation of insulation in the form of foam plastic or foil mineral wool, it is necessary to treat the walls with an antiseptic. The foam is glued and fixed with self-tapping screws. Gaps can be filled with construction foam. At the end, finishing work is carried out.

Methods for forced drying of the cellar

There are several simple and effective ways to dry the cellar without ventilation, which are preceded by cleaning the room and treating with antiseptics:

With the help of a household dehumidifier, which conducts air through itself and removes excess moisture from it.
An iron stove is installed in the basement and heated until the desired result is achieved.
You can disinfect and drain the basement with the help of a brazier, equipped inside a tin container and lowered inside to the floor level. The heat from the fire will quickly warm the air in all planes, and the smoke will destroy insects and fungus.
Any heater will help get rid of excess moisture. Their application can take a long time and require energy costs.

Before drying the basement after flooding with water, if, in addition to high humidity, all surfaces are impregnated, and most of all the floor, dry sawdust should be spread, cardboard boxes, newspapers or other absorbent materials should be laid out. It is also recommended to use lime and potassium chloride, which will remove excess moisture and disinfect the room.

Folk methods of dealing with dampness

It is possible to remove dampness in the cellar without the use of modern chemicals and electrical appliances. Some methods are longer, others are designed for short-term use:

Heated bricks, located along the walls around the entire perimeter, will perform the function of a heater. High temperatures dry the air and reduce humidity.
Simple lime, which is applied in a thick layer, can return the normal state of the microclimate to a damp basement. It quickly and effectively collects moisture from the air.
You can enhance the effect of lime by adding copper sulfate to a ready-made thick solution.
Calcium chloride dries the air perfectly. It is abundantly scattered throughout the basement and left for a day. Then the room can be warmed up and used again.
Sawdust will help to quickly remove moisture. They must be scattered in a thin layer and wait until the wood chips get wet. Then the mound is removed and a new one is poured. Instead of sawdust, you can lay out newspapers or cardboard.
Salt and ash are also temporary adsorbents.

How to prevent the appearance of high humidity?

The question of how to get rid of condensate in the cellar or get a dry basement should be asked at the construction stage, choosing a material with the lowest hygroscopicity for walls and ceilings.

In addition, it is mandatory to equip drainage lines, waterproofing and insulation layers both outside and inside.

An important stage in the arrangement of a food storage room is not only the installation of racks and flooring, but also a high-quality ventilation system. It should not only draw air from the basement, but also ensure its replacement with fresh air.

Every year, it is imperative to carry out a general cleaning of the cellar, get rid of spoiled food, dry and whitewash the walls. When installing furniture, leave a small distance from the wall to ensure ventilation of all problem areas.

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 number of complex works on the qualitative organization of the main systems.

One of the simplest ways is to install containers filled with white moss powder.. 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 drained using ceramic bricks heated to a 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 of 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 an important point, since in the presence of closely spaced groundwater it will not be possible to eliminate dampness 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.

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.
Using a fine-grained cement-based composition, various depressions are overwritten, otherwise small bubbles may remain after applying the mastic.
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.
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).
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.
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 of bituminous mastic is carried out in 2-4 layers, but it all depends on the operating conditions of the basement and external factors (groundwater occurrence, 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 humidity can be maintained, because air flows must move correctly.

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

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.
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.
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.
At the last stage, 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.

For most summer residents and suburban residents, dampness in the cellar is a huge problem. The reason for the increase in humidity is considered to be poorly made heat or waterproofing. Another reason may be the lack of a ventilation system.

Whatever the reason, a wet basement is not suitable for food storage. Therefore, moisture must be removed and disposed of condensate. We will tell you today how to dry the cellar, disinfect and prepare it for laying the crop.

How to dry the cellar

For drying, choose a dry sunny day. First of all, we take out all the products and boxes left there, we also need to remove the shelves, disassemble the racks, pallets. Next, you need to sweep out all the debris and sand. If there is water, it must be pumped out.

All existing structures are cleaned with hot water with the addition of soap and baking soda. Further, all parts are treated with a solution of lime and copper sulfate. This will help get rid of fungus, mold and harmful bacteria. After that, all parts are left to dry in the sun for several days.

Note: The places where the furniture stood are thoroughly washed from dirt and mold. For greater effect, you can use a mixture of salt and sulfuric acid, which is left inside for three hours.

After that, we open the doors, all ventilation pipes and hatches to dry the room.

How to quickly dry the cellar from dampness with ventilation

There is a certain algorithm for drying underground storage, which depends, first of all, on the presence of ventilation in it. Consider how this process occurs in rooms with ventilation systems or openings.

We heat the cellar

If the weather is warm outside, and dampness needs to be removed now and ventilation does not help, you need to heat the air. To do this, take an old metal bucket, make holes in the bottom and walls. Then they are securely attached to the cable and the coals are poured into the bucket. The coals are kindled and set to a constant burning. A bucket of smoldering coals on a cable is lowered into the basement and fixed so that it hangs above the floor, and the room itself is closed (Figure 1).

Doors need to be opened every 20-30 minutes. But you can not climb inside, as the temperature there is high and carbon monoxide accumulation is possible. After the coals have burned out, we take out the bucket and close the cellar. You can’t look inside for three days, the smoke will kill the mold and disinfect the room. In this way, you can get rid of dampness in the basement under the garage.

Figure 1. Drying the basement by heating

Instead of a bucket of coal, you can use: a potbelly stove (just lower it into the basement and heat it), a high-power heat gun, a propane burner or kirogaz. However, it should be borne in mind that these methods are considered quite dangerous and cannot be used alone.

How to dry the cellar from dampness without ventilation

If a ventilation system was not installed during the construction of the basement, it is necessary to equip some kind of pipes. They can be brought to the wall or ceiling. You can also purchase a fan with a supply and exhaust mechanism.

After flooding, you first need to pump out the water. Then take everything out, dry with open doors and hatches and whitewash with lime. After that, you can use the methods described below.

A cellar without ventilation can be dried using hydrophilic materials:

Slaked lime - destroys the fungus and removes moisture. Arranged on shelves and along walls.
Dry sawdust - contribute to a decrease in humidity.
Calcium chloride - tends to absorb moisture. Lay out, collect in a day, calcined and can be used again.
Dry cardboard boxes are used to prevent condensation on the ceiling.

You can purchase special equipment - a household dehumidifier, which can also effectively cope with the problem of high humidity.

Disinfection and fight against fungi and mold

After drying, they begin to fight the main problem of underground storage - mold and fungus. There are several effective methods for this, which we will describe below.

Vapors of lime

Lime is a quick and inexpensive way to get rid of fungus. It is used to combat colonies of fungi and for prevention.

Before starting work, pre-treatment of the premises with deactin is carried out. The drug is diluted in water, then applied to all painted surfaces.

Figure 2. Disinfectant treatment with lime

There are two folk recipes by which you can clean the basement from the fungus with lime:

Lime mixture with copper sulphate. To do this, take two buckets of water 1 kg of slaked lime and 100 g of vitriol. Apply with a spray gun (Figure 2).
mixture with formalin. For a bucket of water, 200 g of formalin and 500 g of bleach are used. The resulting solution lubricates all surfaces inside the basement. After that, the room should be dried and ventilated.

Sulfuric (smoke) bomb

Sulfur gas vapors are considered an effective method for removing fungus. To use a sulfur checker, you need to block the access of air to the room, put the checker in a tin basin and set it on fire. Then quickly exit and close the doors tightly (Figure 3).

Figure 3. Disinfection of the cellar with a pair of sulfur checkers

Be careful, as sulfuric smoke is dangerous to people and animals. After 12 hours, the room must be thoroughly ventilated and treated with slaked lime.

Mold remover

There are cases of white fluffy mold. This is one type of fungus. To combat it, use the methods described above, and you can also use a foam remover.

By applying the product to the place where the fungus appears, the mold immediately begins to curl. In the future, the treated area does not appear.

Sprinkling on the floor

If your basement floor is earthen, you can put a thick plastic sheet on it (this will prevent excess moisture from building up).

To do this, make wooden bars and put them on the floor. Scatter pieces of slaked lime over the film. This will help prevent fungal growth and thus reduce moisture.

How to dry the cellar after flooding

You need to start drying immediately after flooding, as mold forms quickly. First you need to pump out water in a way that is accessible to you. Next, take out all the pieces of furniture. The cover and ventilation hatches should be opened.

When most of the water is removed, you can install fans in the cellar and direct them to the walls of the room. If possible, use a dehumidifier.

A dried room should be treated for fungus with copper sulfate or use a ready-made anti-mold agent. Walls should be whitewashed with lime. Don't forget to use rubber boots and gloves while drying so you don't get electrocuted.

A quick and easy way to dry the basement is shown in the video.

How to dry the cellar in the garage from condensation

To get rid of high humidity in the garage, you should install a good ventilation system:

Install one pipe for inflow, the second for outflow;
Mount one pipe (through the ceiling or wall) with an exhaust fan.

If the condensate has already entered the garage, you can use several proven methods for removing moisture:

Arrange slaked lime along the perimeter of the walls and on the shelves. This will get rid of the fungus and reduce moisture.
Spread dry cardboard boxes on the floor. Change as moisture accumulates.
Scatter dry sawdust on the floor and change as it gets wet.

You can also use dehumidifiers. The device model for this should be selected with medium power. After the walls are dry, they should be whitewashed with lime.

Every spring, carry out preventive drying. After heavy summer and autumn rains, the room should also be dried. If you carry out preventive work, the fungus will not be terrible for you.
