Geosynthetic Clay Liner Used for Dam Liner
Geosynthetic Clay Liner Used for Dam Liner
Product Description
Name | Geosynthetic Clay Liners |
Description | Geosynthetic Clay Liners is made from high expansibility of sodium bentonite filling in a special composite fabric and nonwoven cloth, and between the use of acupuncture legal system into bentonite seepage control pad can form many small fiber space, make bentonite particle can't flow in one direction, treat water in the GCL form even high density of colloidal waterproof layer, effectively prevent the leakage of water. |
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 | |
Application | It is mainly used in municipal services,roads,railways,water conservancy,environmental protection and industrial and civil buildings in the construction of underground seepage control. Unlike the membrane,its unique role include: 1. It is used in the landfill sites under the primary geomembrane lining. 2. It is used in the landfill under the sub-lining of the geomembrane. 3. Under the landfill geomembrane and below the clay layer,that is the lining of three components. 4. Under the geomembrane in the landfill cover layer. 5. Adjacent with the geomembrane in the vertical cut-off water wall. 6. It is used on the geomembrane to prevent the coarse-grained materials puncturing the geomembrane. 7. It is used as the second layer of underground water wells linging. |
