Product Description:
GCLs have become the gold standard clay component of composite lining systems used in industrial, hazardous and municipal solid waste landfills. Used alone or in combination with a geomembrane in a composite cover system, GCLs provide significantly lower permeability, improved ease of installation, an increased amount of usable space. In many cases GCLs are more cost-effective than traditional compacted clay liners. GCLs are also not subject to deterioration from differential settlement and freeze-thaw cycles, which can damage traditional compacted clay liners. Important design considerations for GCLs in landfill caps include confining pressure, and potential for ion exchange and desiccation.

Application:
- All stages of landfill applications Landfills (floor, wall and cap liner)
- Ponds
- Dams and dam wall liner
- Containment areas
- Cut-off walls
- Canal Linings
- Waterproofing concrete structures
- Road/Rail embankments
Installing Note:
1, Before GCCM construction, foundation should be inspected, the foundation should be rammed flat, no potholes or water, no gravel or roots or other sharp objects.
2, In the process of handling and construction, GCCM should be to avoid vibration and impact, to avoid large degree of bending.
3. After installing and acceptance of GCCM, backfill shall be carried out as soon as possible. If it is in conjunction with the use of HDPE geomemes, geomemes shall be installed and welded in time to prevent them from being wet or broken by rain.
Advantage:
- Improved leakage performance
- Permanent waterproof performance
- Simple construction and short time limit for a project
- Not influenced by air temperature
- A kind of green material and good to environmental protection
- More versatile than compacted clay
- Increased airspace and liner efficiency
