Geosynthetic Clay Liner, 5500GSM Bentonite Waterproof Pad For Landfill

Bentonite Waterproof Pad (GCL) consist of clay material and geotextile. About the clay material, it is usually bentonite, which is sandwiched between two layers geotextiles. This lining mechanism is mechanically bonded by needle punching from one nonwoven geotextile through the bentonite to the other nonwoven or woven geotextile. The bentonite swells and extrudes through the geotextile fabric at the overlap, forming a seal by producing a dense and uniform clay barrier with the same hydraulic qualities in all parts of the clay liner.

• Improved leakage performance
• Permanent waterproof performance
• Simple construction and short time limit for a project
• Not influenced by air temperature
• Environmentally friendly material
• More versatile than compacted clay
• Increased airspace and liner efficiency

The Bentonite Waterproof Pad is suitable for:

• New civil engineering planted roof garden, basement, roof and other water projects
• Subway, railway, municipal roads, light industry, petroleum and metallurgical industries
• Earthwork repair and reinforcement of anti-seepage projects
• Desert governance, environmental reform, landfill, artificial lakes, man-made landscape soil waterproof blanket
• Water conservancy projects including large area water seepage construction, small reservoirs, dams, irrigation canals, and ponds
