FIELD: construction.
SUBSTANCE: previously a trench is dug along the perimeter of an erected impervious screen. The sealing mixture is injected, for instance, a cement mortar, with the help of high-discharge injection to the rated length along the inner perimeter of the trench, then - along the outer perimetre of the trench. After hardening of the sealing mixture high-discharge injection is carried out in the middle part of the trench along the entire length, and drainage pipes are laid into the trench.
EFFECT: higher efficiency of works performance and reliability of a developed impervious screen.
