Drying cellars with high humidity

owners of private homes should have an idea as to dry the basement with an increase in the humidity level.

The appearance of dampness in the cellar can cause all sorts of reasons: flooding, groundwater infiltration, condensation can form on the walls.

sometimes manages to get rid of moisture quickly and without major financial outlay.

In other cases, in order to dry the cellar, will require major construction work and some financial investment.

Taking care of basement waterproofing and ventilation needed at the construction stage.But you can take steps to eliminate the moisture in the finished building.

How to prevent moisture still under construction:

• With the construction of the cellar in a private home or garage, do not use bricks and porous materials (foam and keramzitobloki, shell).The best material for the walls and floors - is concrete;
• Perform construction work in the summer in dry weather in order to prevent the ingress of groundwater into the pit;
• Make waterproofing walls and floors;
• Take care of ventilation.Properly organized air exchange to prevent the appearance of condensation on the walls and mold growth;
• Note the groundwater level, if there is a danger of flooding, do indoor or outdoor drain.

If ground water does not rise above the level of the floor, the basement waterproofing can be used bitumen or heated mastic.

After application to the walls and ceiling materials are polymerized and form a protective film on the surface.A more reliable method of protection is penetrating waterproofing.

material impregnates the wall, thus altering their structure.Penetrating the insulation reliably occludes all cracks that makes concrete more frost-resistant and strong.

There is a waterproofing membrane based on polymers.After application of the material is converted into a membrane impermeable to water.

Properly organized ventilation in the basement consists of the exhaust duct and inlet openings.

Exhaust duct installed in one corner of the room, on the ceiling or the top of the wall.

upper end of the tube is located above the ridge of the roof 0.5 meters.Duct mounted vertically to reduce the amount of condensation, its outer part should be warm.

through air hole in the basement served fresh air duct is installed in the opposite corner of the drawing.

Moreover, the lower part of the channel should be placed at 30 cm from the floor.Supply and exhaust openings are closed mosquito net.This ventilation is under the influence of the natural traction.

Fresh air enters into the bottom of the basement, gradually warming up, goes up and is removed through the exhaust port.As

own dry cellar?

best time to drain the basement in the house or the garage - this summer.Older stocks virtually came to an end, and the period of the new pieces had not yet begun.

Pre basement is fully exempt from stocks of fruit, vegetables and preserves.It is also necessary to dismantle and take out all the designs for the storage of reserves.

doors to the room should be left open for several days, thanks to the basement, you can quickly dry the condensate from settled.

To expedite the process, experts recommend to put in a basement box with moisture capacity material such as dry lime or charcoal.

While the room is ventilated, get handed down from the construction of the basement.Wooden shelves to dry in the sun and wash with soapy water.

Finally, the tree is covered with a layer of whitewash from the addition of copper sulfate.To kill mold, you can burn construction blowtorch.

metal elements also need to be dried, then cleaned of rust and paint.

After airing the basement walls and floor are cleaned of debris and treated with a solution of potassium permanganate.

To permanently destroy the mold and larvae of pests, basement ventilation is recommended to fumigate after special smoke bombs with sulfur.

They can be bought in stores selling farm implements.

If the basement is still a high level of humidity and mold, it is recommended to resort to one embodiment of forced drying.

What additional tools can be used to dry the cellar in the house or garage:

• metal brazier - brazier as you can use an old metal bucket with the work done at the bottom of the holes for the rods.It is necessary to attach the bucket leg and hook with rope, with which the roaster will descend.A bucket filled with firewood or charcoal.After kindling the flame roaster goes down and set on a flat, non-flammable base.To completely dry the basement, the fire must burn for at least 12 hours.To go down to the basement during the fumigation is prohibited, for by putting a bucket of fuel needed to pull up.Use the brazier to dry the cellar, it is possible only in rooms with concrete or dirt floor;
• Candle - to dry the cellar after penetrating groundwater, regular lighted candle is placed in an iron pot and set in the vicinity of the exhaust opening.Entrance doors with stay open.Burning flame enhances traction, breathability is more intense, to replace the stale air flows come hot off the street.In order to dry the cellar instead of candles can be used with dry alcohol burner;
• Electrical Appliances - set in the middle of the basement or infrared oil heater.Such a process can be time consuming, so if you can, it is better to replace the heater heat gun.Due to the high heat capacity of the gun, the method can be operated in order to dry even after penetration cellars sewage and groundwater.

device

drainage system With a high level of ground water table is necessary in the construction of the basement to take care of the device drainage system.

If this is not done, the cellar will be periodically subjected to flooding.The most commonly used external drainage system, it is possible to build around the already finished buildings.

main difficulty - have to dig the foundation around the perimeter of buildings.If this is not possible, it is better to stay at a more accessible home drainage.

drainage base - is a perforated tube through the holes which will seep underground water and rainfall.The tube is placed on the soles of the level around the perimeter of the basement.

Keep in mind, internal drainage does not guarantee a perfect result.Besides, after all the work is below the basement at least 30 cm.

Therefore to this method is resorted to only in extreme cases.

device internal drainage:

1. good dry cellar after the penetration of groundwater;
2. waterproofing walls, better with penetrating materials.In extreme cases, use a liquid rubber;
3. Remove the finishing floor (if any) and pour on the base plate layer of gravel;
4. top of crushed stone cushion lay the perforated pipe and bring them out of the basement into a well to collect water;
5. pillow lay on the crushed stone layer of insulating material and make concrete screed.This will be the new floor.

device external drainage:

1. After removing the formwork foundation cover waterproofing materials;
2. Dig around the basement draining trench.Ditch should be positioned at a slant to the location of water collection (drainage wells);
3. Dig a drainage well.It should be placed at a distance of no more than 10-15 cm from the cellar.The walls of the well reinforce the casing diameter of 300 mm and a depth of at least 3 m;
4. Make a trench for a pipe connecting the drainage and catchment well;
5. Submit at the bottom of the drainage trench geotextiles and sprinkle a layer of gravel;
6. Place the drainage pipes, pour gravel and close the edges overlapping the geotextile;
7. Connect the drain pipe drainage wells;
8. Fill the trench with soil previously selected.

Construction works better to spend the summer.If the basement is located in the area with loose soil, the trench wall must first be strengthened.
