Our Composite Geomembrane Chosen By New Clients


The choice of composite geomembrane specifications is related to the flatness of the underlying layer, the material's allowable tensile stress, the elastic modulus of the material, the larger water head in the laying range, and the larger particle size of the cover layer. The thickness design is mainly determined by water pressure requirements. 

In addition to the strength, it is also necessary to consider the application conditions such as exposure, buried pressure, weather, and service life, and determine the design thickness and actual thickness according to the relevant national standards.

Construction Notes

Renovation of anti-seepage system shall consist of cushion layer, anti-seepage layer, transition layer and protective layer.

The soil should be solid to avoid uneven subsidence, cracks, and turf and tree roots within the impervious area. Sand or clay with a small particle size is laid on the contact surface with the film as a protective layer.

The geomembrane should not be pulled too tightly when laying, and the part embedded in the soil at both ends is better to be corrugated, especially when anchored with rigid materials, a certain amount of expansion and contraction should be left.
