Product Description

Bentonite Waterproof Membrane  Geosynthetic Clay Liner Gcl

Bentonite 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.

 

Bentonite Geosynthetic clay Liner GCL Production Line:

 

Bentonite 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

 

Bentonite Geosynthetic clay Liner GCL  Packing:

 

Bentonite Geosynthetic clay Liner GCL Applications:

 

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.

Note: 

1, The EltGCL Weight can do from 3000g/m2 to 7000g/m2.

2, The EltGCL is a reinforced GCL consisting of a layer of sodium Bentonite between a woven and non-woven geotextile, which are needle punched together.

3, we also have Needle punched and coated process GCL and Viscose pmcess GCL.
