Geobag Manufacturers

Repairs should be postponed to areas at least 30 cm outside the size of the damaged composite geomembrane.

The anti-seepage geomembrane is a new type of synthetic geotextile waterproof barrier material produced in the 1980s.

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 geomembrane at the bottom of the reservoir can be laid after excavation and filling of the dam in the reservoir area.
