The foundation, in contact with groundwater, accumulates moisture (capillary effect). Water in the structure of the building material causes a decrease in its strength. Microorganisms that are harmful to humans develop. To avoid this effect, a waterproofing injection method is used.

   Through the packers, the insulation mixture is supplied with or without pressure. Before that, the drilled holes for them are cleaned of dust. After pumping hydrophobic materials, the holes are sealed, and the structure becomes stronger and more resistant to moisture.
