geomembrane pond liner Manufacturers

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 raw materials used for composite geomembrane should not only take into account the physical and chemical performance indicators specified in the use environment, but also pay special attention to the production cost. In terms of performance indicators, the following aspects are mainly considered:

The selection of geomembrane should be comprehensively considered in terms of engineering application, economy, construction technology characteristics and material performance. First consider whether the permeability and quality meet the requirements. Secondly, in order to prevent damages encountered during transportation and construction, geomembrane must have good mechanical properties such as anti-permeation, anti-puncture, and tensile strength. Of course, during construction, we must also take care to protect it from damage. In addition to the above points, durability and thickness should also be considered.

High-density polyethylene (HDPE) composite geomembrane is a non-polar thermoplastic synthetic material with high impermeability, corrosion resistance and stable chemical properties.

The composite geomembrane is formed by heating one side or both sides of the film in the far-infrared drying box, and pressing the geotextile and the geomembrane together by means of guide rollers.
