FIELD: construction.
SUBSTANCE: method for developing an antifiltration coating includes preparation of an earth bed, installation of a watertight geomembrane in the form of cloths from polymer materials, installation of a protective liner from geotextile and arrangement of a protective layer. The protective geotextile liner is laid onto the antifiltration element from a geomembrane. A geogrid is fixed to the protective liner by spot welding with perforated walls of cells. Cells are filled with a filler and a gunning cement mix.
EFFECT: higher reliability and durability of a structure, watertightness of an antifiltration coating and hydraulic efficiency of a channel, provides for protection of an antifiltration element against mechanical damages in process of coating operation, eliminates water losses for filtration from canals and water reservoirs, prevention of waterlogging, salinisation and underflooding of valuable arable areas.
