geosynthetic clay layer(GCL)

geosynthetic clay layer(GCL)
Product Detailed
1.Geosynthetic clay layer(GCL) 2.Made from grading natural sodium bentonite particles 3.Suitable for uneven settlement

Geosynthetic clay layer (GCL) is a new type of geo-synthetics. It's made from grading natural sodium bentonite particles and admixtures mixed uniformly. By special technology and equipment, bentonite is fixed between two layers of geotextile which can made bentonite waterproofing blanket. It not only has all the features of the geotextile material, but also has excellent waterproof performance (permeability).

Application Field:

1. Seepage control of Municipal engineering, subways, buildings, underground engineering and the roof of the reservoir.

2. Seepage control of Environmental sanitation, municipal solid waste landfill, sewage treatment plants, industrial waste.

3. The seepage control and reinforcement of water conservation, river, dike and dam.

4. Garden artificial lake of the golf course pond seepage and so on.

5. Petrochemical, mining and other projects' seepage, leakage, etc.
