HDPE geomembrane (high-density polyethylene geomembrane) is an environmentally friendly anti-seepage material commonly used in anti-seepage engineering, and the specifications of HDPE geomembrane are generally distinguished according to the thickness of the geomembrane. The application fields of geomembranes with different thicknesses are also different.

As a new generation of geotechnical impermeable materials, LDPE geomembrane is mainly polymerized by polyethylene, ethylene, ethylene polymer and other materials, which absorbs the flexibility of the previous geomembrane, and increases its good extensibility and ability to adapt to deformation. It greatly increases its waterproof and seepage resistance.

Geomembrane and Geotextile is to paste geotextile on one or both sides of the membrane to form a compound geomembrane. Its form is one cloth and one membrane, two cloths and one membrane, two membranes and one cloth, etc. As the protective layer of the geomembrane, the geotextile protects the impermeable layer from damage. Composite geomembrane is widely used in channel seepage prevention engineering.
