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.

 

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

They are used in landfill caps and base liner applications under roads, railways, secondary containment for above ground tank farms, as well as within various other containment structures such as dams, canals, ponds, rivers and lakes. They are also used for waterproofing of buildings and other similar structures.
