Bentonite Geosynthetics Clay Liner For Waterproofing Gcl Landfill Artificial Lake
Bentonite Composite Waterproof Blanket is a special geosynthetic material used in artificial lakes and water features, landfills, underground garages, roof gardens, pools, oil depots and chemical dumps, etc. It is made of high expansion of sodium bentonite filled in a special composite geotextile and non-woven fabric between the needle-punching method into the bentonite impermeable mat can form many small fiber space, is the bentonite particles can not flow like a direction. When water is encountered, a uniform high-density gel-like waterproof layer is formed in the mat, effectively preventing water leakage.

Product Description
Natural sodium bentonite geosynthetic clay liner Product Introduction; The GCL is punched together with non-woven geotextile,woven geotextile, and bentonite. The width of the geosynthetic clay liners can be up to 6m and the length of 60m. The middle levelis bentonite grains, which are carefully selected crude and filled in between the two levels after special processing. Thebentonite grain in GCL made by this method does not flow in a fixed direction. It distributes evenly and forms a waterproof layer,owning an excellent waterproof effect. This GCL is a kind of new green waterproof material, which is widely applied in manywaterproof construction projects. GCL can be applied separately, or combined with high-density polyethylene (HDPE).
