Geosynthetic clay Liner GCL Description:  
Geosynthetic clay liner
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 nonwoven geotextile are needle punched through the layer of bentonite and incorporated into the other geotextile (either a woven or nonwoven).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.
   
 
Geosynthetic clay Liner GCL Properties: 

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
