In the process of purchasing composite geomembrane, it is necessary to select a composite geomembrane product that meets the specific project and has operational performance according to the characteristics of the project, design plan and related inspection and test regulations.

HDPE geomembrane, also known as high-density polyethylene film, is produced with high crystallinity, non-polar medium (high) density polyethylene thermoplastic resin as raw material, with a density of 0.94g/cm3 or higher.

When we carry out anti-seepage geomembrane construction, we can really pay attention to the correct handling of such small details, so that there will be no leakage, as long as you handle the small details correctly.

When non-expandable damage causes water leakage, such as cracks or problematic joints, the system you use is an external waterstop, and the waterproof barrier is located in the external part above the fault area.

Product quality inspection of composite geomembrane materials.
