Bentonite Waterproof GCL :
waterproof swellable bentonite blanket geotextile membrane clay liner
1. Improved leakage performance
2. Permanent waterproof performance
3. Simple construction
Geosynthetic Clay Liner (GCL) is a kind of gree material and good to environmential protection anti-leakage product.
Geosynthetic clay liners (GCLs) 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).when hydrated under a confining load, the bentonite swells to form a low permeability clay
layer with the equivalent hydraulic protection of several feet of compacted clay.
It is used to prevent water leakages in areas of artificial lakes, waste disposal fields, underground
garage, top building gardens, reservoirs, oil warehouses, and chemicals accumulating fields.
Features:
1. Improved leakage performance
2. Permanent waterproof performance
3. Simple construction and short time limit for a project.
4. Not influenced by air temperature.
5. A kind of green material and good to environmental protection.
6. More versatile than compacted clay
7. Increased airspace and liner efficiency
