With the growth of the service life of expressways, problems such as network cracks, grooves, and cracks have appeared. It not only affects the stability and comfort of the car, but also causes surface water to penetrate into the road base and weaken the bearing capacity of the road base.

The durability problem of anti-seepage geomembrane is a problem that everyone often pays attention to.

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

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.

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.

1. Excellent environmental adaptability: Most of the traditional geomembrane materials have a single performance, and there are not many methods that can be used.
