Waterproof blanket can be used for rail, water conservancy, road, etc., which can better prevent seepage or reinforce
GCL Bentonite Waterproof Blanket
GCL Waterproof blanket is combined with 3 parts. The upper level and the lower level are woven geotextile and non woven textile, the middle level is bentonite clay, which are carefully selected crude and filled in between the two levels after special processing. The bentonite clay in GCL made by this method does not flow in a fixed direction. It distributes evenly and forms waterproof layer, owning excellent waterproof features. This GCL is a kind of new green waterproof materials, which are widely applied in many waterproof construction projects.
Waterproof blanket and bentonite composite waterproof blanket (GCL) is a new geosynthetic material. It is a carpet waterproof coiled material made of graded natural sodium bentonite particles and corresponding additives, and the bentonite particles are fixed between geotextile and plastic woven cloth by acupuncture technology and equipment. Bentonite waterproof blanket not only has all the characteristics of geotechnical materials, but also has excellent waterproof (seepage) performance.
