GCL
geosynthetic clay liner
geosynthetic clay liner
1.Features:
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
2.Usage:
Mainly used in environment engineering of landfill emissions, underground reservoirs, underground infrastructure construction projects, sealing solution, segregation , anti-leakage, good effect, anti-destructive.
3.Specification:
Unit weight ≥4000g/sqm , width :4-6m
4. Certificate:
ISO9001:2008 and ISO14001:2004.
