FIELD: construction.
SUBSTANCE: invention relates to hydraulic engineering and may be used for antifiltration protection of water reservoir canals. The multi-layer antifiltration coating includes waterproof and reinforcing layers. The waterproof layer is made by flexible sheets manufactured from polyethylene wastes, and the reinforcing later is a geonet from polyethylene wastes or geotextile from wastes of textile industry, Flexible sheets are thermally connected to components of the reinforcing layer by melting of sheet surface.
EFFECT: invention provides for high watertightness, durability, reliability in operation at collapsing and heaving soils of the base.
