FIELD: construction.
SUBSTANCE: invention relates to anti-filtration composite materials and can be used for anti-filtration purposes in hydroeconomic and environmental construction on channels of irrigation and drainage systems and water basins without arranging additional protective coatings. A polymeric composite material based on bentonite includes a lower profiled web 1 with polymer channels 2 filled with bentonite 3 and an upper web 4 of an elastic polymeric material, connected to the underlying one by means of extrusion welding.
EFFECT: developed polymer composite material based on bentonite can be used without protective layers, thereby ensuring a minimum surface roughness and, as a result, maximum throughput capacity on irrigation channels, reliable anti-filtration protection due to self-healing of possible damages.
