Before proceeding to strengthen the base of the house, it is necessary to remove the loose elements of the foundation. In their place it is required to dig a trench. It should go around the perimeter of the building and place closely. Then build formwork from plywood to the bottom of the wall.
Fall asleep with a sand pillow 10 cm thick. The presence of a compensator under the basis is a prerequisite. The structure should be surrounded by a welded grid. For a bunch of parts, wire is used in a single frame. The space of the trench is poured with concrete.
The base base can protrude from the surface of the wall by 5-20 cm. It is advisable to close the protrusion with metal castings, placing them at an angle so that the water drains away from the wall. Around the house you need to make a blind area 60-90 cm wide. So that the foundation is less destroyed, the blind area should be placed under the slope.
To build a blind area, it is necessary to remove the soil to a depth of 15 cm. Then pour a sand layer 10 cm and perform a concrete screed 5 cm thick. So that the screed does not crack, you need to waln down a welded grid in it.
If the building gave a shrinkage only on one side, the foundation should be divided into parts. First, dig a trench to the first element, then mount the formwork and fill the mixture. When the solution gains strength, proceed to fill the next part.
