Dampness and mold in the cellar
first step is to ventilate and dry cellar.Inspect the walls and floor of the room and identify the places of water infiltration.Find damage in the walls or in the floor and begin to repair.You can use several options to improve waterproofing cellars.
damp cellar wall
If one wall is damp cellars need:
- with its outer side to remove blind area along the building;
- dig a trench, abutting against the wall, a depth of 0.5 to 1.0 m and a width of 0.2-0.3 m;
- clean the basement walls from adhering soil and dry;
- melt the bitumen or asphalt mastic and fluff dried her wall.
You can still do so:
dried cellar outer wall plastered with cement mortar (composition 1: 3),
or the same solution, but prepared with liquid glass, which gives the best results
The choice is yours!
plaster and allowed to dry her coat with bitumen mastic.Then the trench stacked clay layers fatty each layer was thoroughly tamped.This is called "clay Castle" and the water into the basement throu
Water enters through the wooden floor
If you find that dampness or water enters through a wooden floor, then you need:
- dismantle and remove the floor of the room wet boards, bars;
- compactor align the floor and lay carefully tamping, greasy clay layer
- the new clay floor paving bitumen mastic 2-3 layers of roofing felt or tar paper
, waterproofing or other rolled waterproof material;
- top put a layer of concrete and cement screed to do.
dismantle and remove the floor of the room wet boards, bars;
Water enters through the concrete floor
If water enters the basement through the concrete floor, it is necessary:
- floor clean and dry;
- put on a dry floor 2-3 layers of roofing felt or roofing material, promazyvaya
- the new insulation layer to make a concrete screed thickness of 6-8 cm or
put a layer of cement mortar with liquid glass, a thickness of about 0.5 cm.
Now that the necessary works are completed, you can re-lay a wooden floor or a more practical lightcomfortable and wooden shields.They can be removed at any time for drying or repair facilities.
Mould also not a gift!
First of all, the cellar should be annually whitewash with lime mortar and sulphured.But if there was still mold - start with disinfection:
- from the basement all the need to remove (drums, containers, utensils, food supplies, etc.);
- Close ventilation;
- Centered cellar higher, install earthenware vessels, to pour into her
table salt - 1 kg.There also carefully pour 1 liter of sulfuric acid and immediately
get out of the room, closing the door tightly.Cellar began perfumed vapors of sulfur
it takes a few hours;
- Over time, open the door and ventilate the cellar.When sulfur vapor weathered, open vents.Ventilate the basement, you can start cleaning.
necessary to carefully wipe the walls and ceiling of the mold.Clean the floor.Whiten mortar space, which will give him a good look, Clean and disinfect the air.Mould is now long appears.
Dampness in the basement
Another factor in damp basements, especially in the garden house is a seasonal fluctuation of groundwater level.
their regular lifting can cause flooding of the basement, in the presence of the walls and floor cracks, or fistula.Restore waterproofing premises, you can use cold asphalt mastic or watertight solution.
begin restoring waterproofing cellar only when the level of ground water below the floor.That is, you need to wait until the water goes.
Now that the water is gone, thoroughly inspect the walls and floor.Find a place of penetration of water in the basement and butchered them all over in the groove depth of 30-50 and a width of 20-50 mm.To deepen and broaden the groove by hand into a wall or floor in places flowing water, use a chisel.Prepared groove washed with water, blotted and dried cloth.
If waterproofing is used to restore the cold asphalt mastic sealing of the cracks and fistulae begin with cement mortar.They do not fill the entire depth of the split groove, and by about one third.The solution was to grab.Then a layer of bituminous cold pasta thickness of 1-2 mm and left to dry for 8-12 hours.After time, the last layer of pasta covered twice (3-5 mm) cold asphalt mastic, taking a break to dry layers.The final touch - a dried layer of mastic covered with cement mortar and align flush with the surface.
If used for restoring waterproofing waterproof solution, the initially prepared a cement-sand mixture (1: 1 or 1: 2 by volume).All the components are dry blended in a container, and shuts the water instead of sodium aluminate solution density of 1.44.The desired concentration of aqueous sodium aluminate solution selected empirically using (dry mix: water solution) 1:15, 1:10, 1: 5 by volume.The temperature of the solvent must be from +10 to + 30 ° C.After mixing the mixture is thoroughly stirred for about 2 minutes, until smooth slaboplastichnoy weight, type of moist earth.
This solution is quickly placed in layers to cut the cracks and fistulae.Caulking compacted and leveled flush with the structure.
Warning!Prepared by the above technology solution grasped within 20-30 minutes.Use it again not!
That's it!Your basement dry and clean!
