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.

Laying HDPE geomembrane is the most important part of the anti-seepage system. The quality of the geomembrane itself and the quality of welding construction directly affect the success or failure of the entire anti-seepage project.

When overlapping with the adjacent composite geomembrane, first expose the geotextile at the joints, sew the adjacent geotextile of the lower layer, adjust the welding edge of the two membrane layers, and weld the middle of the composite geomembrane with an overlap width of 150mm body.

Geomembrane is a flexible geosynthetic impermeable material, and the stability of its underlying support layer is one of the keys to the safety of geomembrane. If the underlying support layer has obvious uneven deformation and local erosion, the geomembrane will be partially torn, forming a leakage channel, threatening the safety of the project.
