Product Details

Geosynthetic clay liner GCL, is also called “clay blankets”, “bentonite blankets”, “bentonite mats”, “prefabricated bentonite clay blankets” or “clay geosynthetic barriers”.

Geosynthetic Clay Liner 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).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.

Good Quality Visible

Features

The Permanent Waterproof

No happen aging or corrosion phenomena, so the waterproof performance persistence

Compactibility

Sodium base bentonite under water pressure condition to form diaphragm with high density

Not Affected By Temperature

In cold climates will not brittle fracture

Environmental Protection

Bentonite as natural inorganic material,no special effects to the environment, have good environmental performance

Simple Construction

Construction is relatively simple, don't need to be heated and paste. With bentonite powder and nails, washers, etc are connected and fixed.

Strong Self-Restore Capacity

The integration between waterproof material and its target enables GCL a 20~28 times swelling volume
