To prevent groundwater from entering the walls of the building during construction, waterproofing the foundation is used.
It is necessary to pour a layer of cement, 2-3 cm high. After lease and dry. Ruberoid and 2-3 layers of hot mastic are laid on top. Next, you need to wait a bit so that everything is dry well. After that, it is necessary to lay 2 layers of waterproof with an overlap of 140 mm. Bitumen mastic and a waterproof layer are placed on top of the foundation. Usually experts recommend cement to buy from a trusted company.
If there is a high level of groundwater, then the waterproofing of the foundation is first isolated by a layer of clay by 250 mm.
Water adversely affects not only on the basis of the house, but also on the foundation itself. In order to protect it from precipitation, from heavy rains and talus snow, you need to make a blind area 20 cm wider than the roof overhang along the perimeter of the entire house.
If the soil is dry, then in this case, for waterproofing the foundation, it is enough to coat it from the outside a couple of times with bitumen.
If the level of groundwater occurs, then waterproofing is used above the depth of the foundation, which is pasted from rolled materials. It is desirable to pour a layer of crushed stone, before that it needs to be impregnated with bitumen.
