Geosyntheic Clay Liner GCL 4500g/m2
Geosyntheic Clay Liner Description:
EltGCL consisting of a layer of sodium bentonite between a woven
and a non woven geotextile,which are needle punched together.
Geosyntheic Clay Liner 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. Green material and environmental protection.
6. More versatile than compacted clay
7. Increased airspace and liner efficiency
Geosyntheic Clay Liner Potential 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.
