We, Shanghai Yingfan, is a geosynthetic clay liner (gcl) manufacturer in China. Our GCL price is competitive in abroad and domestic market with good quality.

Geosynthetic clay liner Introduction (GCL-NP) (bentonite geosynthetic clay liner)

It is bentonite geo-synthetic waterproofing barrier. It is self-attaching and self -sealing to concrete or other construction structures. It is made of a non-woven geotextile, a natural sodic bentonite layer and a polypropylene sheet.

The three layers are connected with a dense felt that makes the bentonite a self-confinement with controlled expansion. With this system it is possible to avoid slippage and the accumulation of bentonite as a consequence of cuts, tears, vertical applications and movements.

Its performance can meet or exceed GRI-GCL3 and our national standard JG/T193-2006.
 
Functions
The engineering function of a GCL is containment as a hydraulic barrier to water, leachate or other liquids and sometimes gases. As such, they are used as replacements for either compacted clay liners or geomembranes, or they are used in a composite manner to augment the more traditional liner materials. The ultimate in liner security is probably a three component composite geomembrane/geosynthetic clay liner/compacted clay liner which has seen use as a landfill liner on many occasions.

Application
1. Roadway separation and stabilization
2. Landfill leachate collection
3. Steepened slopes
4. Retaining walls
5. Embankments over soft soil
6. Lagoon closures
7. Silt fence
