Geosynthetic Clay Liner (GCL)

Geosynthetic Clay Liner (GCL) 1.Environment friendly 2. Permanent waterproof, excellent performance 3. Easy to construct,

Material:Geosynthetic Clay Liner (GCL) is composed of 3 levels. The upper level and the lower level are woven geotextile and non woven textile. The middle level is bentonite grains, which are carefully selected fand filled in between the two levels after special processing.

Product Features:

 

 Geosynthetic clay liners’ weight is uniform, permeability is strong, flexible is good, and can be suitable for the uneven foundation settlement, and to prevent the soil loss, cracks and other defects with a good healing.

                                            

 Product Functions:

 

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 lining.
