Impermeable geomembrane is made according to national standards and special requirements, and it has advantages different from ordinary impermeable membranes.

The purpose of geomembrane is to use its anti-permeability effect. Geomembrane should be impermeable to the molecular structure and manufacturing process. However, due to the unevenness and defects in manufacturing, the commonly used geomembrane must not leak. It's just that it is relatively difficult to permeate and what is more important is whether the geomembrane can maintain its anti-seepage performance under the action of long-term water head when it contacts the actual soil (or other materials). Due to the uneven contact surface, rough soil particles, large local deformation of the soil, etc., the geomembrane may be broken or torn under the action of high water head, and its anti-seepage performance will be lost or weakened. Therefore, corresponding anti-seepage tests are also required.

In which fields can the anti-seepage geomembrane be used, I will give you a detailed analysis today.

The geomembrane currently used in our country is mainly high-density polyethylene geomembrane.

Geomembrane can be divided into types of polymer materials. Geomembrane has excellent properties in terms of tensile resistance, aging resistance and corrosion resistance.

When constructing geomembrane, we really need to pay attention to these details to avoid leakage problems.
