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.

The villagers built a small earth-rock dam on the river. After years of use and operation, many problems and defects have appeared. After investigation, a leak was found at the top of the dam.

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 composite geomembrane uses the following new technologies to improve the anti-seepage effect.

In order to ensure the smooth progress of construction, all employees involved in the purchase of geomembrane must be made aware of the use of geomembrane parameters.

The composite geomembrane has corresponding deformation variables, and the stress caused by the concave and convex defects of the underlayer can be quickly transmitted and dispersed, and the strain capacity is strong.
