Waterproofing foundations: some ways
Waterproofing the foundation is one of the mostimportant works in the construction, because it is because of it that the building will have a good protection against the effects of moisture. The importance of waterproofing increases many times in the event that the building has a basement or a basement.
If the foundation is stone or brick, thenisolation from the effects of moisture is laid at a height of about 20 cm above the ground. Waterproofing foundations in several ways. All the methods that will be described below are the most tested and common in construction.
So, the first way. First lay a layer of cement mortar, the thickness of which is about 3 cm, prepared in a 1: 2 ratio. Then a layer of roofing material is spread. Over the ruberoid, several layers of hot mastic are laid, with a total thickness of up to 10 mm. Then, in several layers, a birch bark is applied using pine resin, and in the end, two layers of roofing material and two layers of bituminous mastic are alternately applied.
The next method by whichwaterproofing foundations, - horizontal, which can be carried out in different ways. If the soil on which the building is built is not moist, it will be sufficient to cover it with bituminous material to protect the base from the effects of moisture. And if the soil is quite wet, then in this case, using liquid mastic, the entire foundation should be pasted with a waterproofing material. With this method of waterproofing, you need to ensure that the entire surface of the foundation is fairly flat.
Modern way to protect the foundation fromexposure to moisture, rain, melting snow and the like is a penetrating waterproofing. In this case, the foundation surface is treated with special materials at a temperature above 5 degrees. Such a waterproofing material penetrates deeply into the pores of the basement and crystallizes there. Thus, in the foundation there will be no cracks and pores, through which moisture can penetrate.
