The anti-seepage geomembrane is a kind of milky white translucent to opaque thermoplastic resin.

Composite geomembrane is widely used in irrigation projects and is a new type of anti-permeability material used to treat roadbed diseases. Due to its excellent anti-permeability, excellent frost resistance, convenient structure and low engineering cost, it is expected to be widely used in road disease management in the future.

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.

The selection of composite geomembrane should be considered from the fields of engineering application, economy, construction process characteristics and raw material characteristics.

In fact, waterproof geotextile is also known as geotextile. Its total width is 4-6 meters, and its total length is 50-100 meters.
