Geosynthetic Clay Liner, Bentonite Waterproof Pad For Landfill
Bentonite Waterproof Pad Description
Bentonite Waterproof Pad (GCL) consist of clay material and geotextile.About the clay material, it is usually bentonite, which sandwiched between two layers geotextiles. This lining mechanism is mechanically bonded by needle punching from one nonwoven geotextile through the bentonite to the other nonwoven or woven geotextile. The bentonite swells and extrudes through the geotextile fabric at the overlap, forming a seal by producing a dense and uniform clay barrier with the same hydraulic qualities in all parts of the clay liner
