The main scope of the injection method is the elimination of construction errors that cause leaks. The injection of a hydrophobic composition is carried out where the protrusion of moisture is localized. At intervals of 30-50 cm, a series of small holes are drilled. The distance between the rows, the angle of drilling depend on the thickness of the base. A packer is mounted in each recess. It serves for sealing, acts as a fitting for connecting the pump.

 Most injection mixes set quickly (15 to 30 minutes). This factor is used to determine the pressurization and holding time. The pressure at the beginning of the exposure decreases, as the mixture is distributed over the pores of the building material. When the pressure stabilizes, this means that the voids are filled to the maximum, and the composition began to harden. After curing, the holes from under the packers are sealed with cement with expansion properties. The surface is impregnated or coated with protective coatings.
