GCL Bentonite Geotextile Mat Waterproof Blanket Geosynthetic Clay Liners
GCL Bentonite Geotextile Mat Waterproof Blanket Geosynthetic Clay Liners
Product Description
Geosynthetic Clay Liners, also called Geosynthetic Clay Liner (GCL), is a new type of composite geosynthetic material widely used in a variety of environmental containment applications as an alternative to traditional compacted clay liners to satisfy your exact project requirements. Geosynthetic Clay Liners is made with the sodium bentonite particles are filled between a woven geotextile and a non-woven geotextile, so it is also called bentonite clay liner. Within the geosynthetic clay liner, the upper non-woven fabric fibers are passed through the bentonite particles, and the special process and equipment are connected to the underlying woven fabric by a special method. Geosynthetic Clay Liners which is made by this method do not flow in one direction, and thus can form a uniform waterproof layer in the entire range. The function of waterproof and impervious Geosynthetic Clay Liners can be widely applied to many engineering construction conditions.
