Product Description

Bentomat Bentoliner Geosynthetic Clay Liner
Geosynthetic clay Liner 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 Properties:

1. Improved leakage performance2. Permanent waterproof performance3. 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

Geosynthetic clay Liner 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.
