Let’s look at 2 ways to eliminate the foundation damage.
1. When waterproofing is entered into the base instead of the absent or destroyed. A basement of a pair of masonry bricks is broken through, is aligned with a solution of cement, and then laying the polymeric waterproofing material of the double layer on the mastic of bitumen. At the same time, the free end of each layer is at least twenty centimeters. The resulting hole is laid with brick.
2. The process of crystallization concrete destruction or leaching of concrete structures.
As they say, in order to know how to eliminate damage, it is necessary, first of all, to establish the cause of its occurrence. The following prerequisites for the foundation destruction are possible:
A) the effect of alkaline (soft) water on concrete;
B) the effect of salt water on concrete.
How to eliminate such damage?
A) the removal of aggressive waters from the foundation or a decrease in their level by building a drainage system;
B) restoration of the structure with subsequent protection against aggressive water. For this purpose, the excavation of soil is taken by a capture of 0.8 meters to the foundation base, the affected parts are cleaned, after which they are thrown by a solution of cement with sand (70% by 30%). In the end, a protective shirt made of bricks, which is saturated with bitumen, and a roofing layer on the mastic of asphalt, is installed. And the last step is to fill the recess with fat clay.
