The waterproofing of the foundation.
The main condition for the integrity and safety of the newly built house or cottage is the correctly performed waterproofing of the foundation, which can be found out in all details here. The floors and walls of the basements, regardless of how underground waters are located, must be completely isolated from soil capillary moisture, which rises up, as well as from surface waters leaking through the soil. In the premises of the basements, with the location of groundwater at least a few centimeters below the floor level, its concrete preparation and the waterproof floor performed on it will be sufficient waterproofing, and it is better to use two layers of hot bitumen for high -quality waterproofing walls. In the same case, if the groundwater level is significantly higher than the floor level, the waterproofing should be more reliable, since it will have to constantly withstand considerable pressure trying to break through it through it.
If the level of soil water is located from the floor at a height not exceeding 0.2 meters, the waterproofing of the walls and floor of the basement should be performed according to the following plan. To begin with, the walls are covered with bitumen, and then a clay castle is formed, or in other words, before pouring the trench, you need to closely place fatty crumpled clay on the outer wall of the basement, according to which a layer of concrete will go after.
When the height of the level of soil water, is 0.2 – 0.5 meters, you use glow waterproofing of 2 layers of euro -ruler based on bitumen mastic. The waterproofing for concrete preparation of the floor is laid, then it is aligned with the surface with a layer of asphalt or a solution of cement.
Since the flooring will withstand the large water pressure from below, the load layer of concrete should be laid on top of the insulation, which will balance the water pressure with its weight. Isolation on bitumen mastic is glued on the outside of the walls and protected by a layer of fat mint of clay 245 thick and masonry made of brick-yellag on a solution of cement.
The glow isolation of any external walls of the basements is located about half a meter higher than the level of soil water, while taking into account its oscillation.
