The description of Waterproof Blanket/waterproofing underground/bentonite waterproof membrane GCL
Waterproof Blanket/waterproofing underground/bentonite waterproof membrane GCL are high performance needle punched environmental reinforced composites which combine two durable geotextile outer layers with a uniform core of natural sodium bentonite clay to form a hydraulic barrier. Fibers from the non-woven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or non-woven).

The advantage of Waterproof Blanket/waterproofing underground/bentonite waterproof membrane GCL
The soil has the characteristics of water swelling. Generally, when the calcium-based bentonite expands, its expansion is only about 3 times its own volume, while the sodium-based bentonite absorbs five times its own weight when it meets water, and the volume expands to the original 15-17. More than double, the sodium bentonite is locked in the middle of two layers of geosynthetic materials to protect and strengthen, so that GCL has a certain overall shear strength.
The Usage of Waterproof Blanket/waterproofing underground/bentonite waterproof membrane GCL
solar panel/Impermeable Material/5Kg GCL for Raiway Waterproofing is used for anti-leakage of artificial lake waterscape, landfill, underground garage, roof garden, pool, oil depot and chemical yard.
