Textured HDPE Geomembrane Liner

HDPE is great because it can handle different temperatures, join together well, resist weather, erosion, cracking, and punctures. It’s especially good for building things underground, like mines, landfills, or sewage systems, because it doesn’t leak. Textured HDPE geomembrane is an improved leak-proof material with one or both sides textured to grip better, making it perfect for slopes and vertical areas to keep them stable and prevent leaks.

    What is Textured HDPE Geomembrane ?

    Compared to the smooth HDPE geomembrane, the textured HDPE geomembrane has two textured surfaces. Their general thickness is between 1.0 and 2.0mm.

    It has lower permeability and a higher coefficient of friction. Textured HDPE geomembrane is mainly used in waste landfills, reservoir areas, and steep slope bases. Textured geomembrane can increase friction and anti-slip, it is more conducive to construction and is safer and more reliable in projects such as steep slopes.

    Technical Notes

    1. HDPE is a very technical product to work with. It must be installed by certified welding technicians using specialized welding equipment to ensure performance.

    2. Installations are temperature and poor weather-sensitive.

    3. 40 mil HDPE liner requires extra effort to ensure that the subgrade is in excellent condition. It is suitable as an upgrade from products like the 20 mil RPE for larger installations and is an excellent secondary containment liner on multi-layer systems (for example; subgrade, geotextile layer, 40 mil

    4. HDPE layer, drainage net layer, 60 mil HDPE layer, geotextile layer, fill.)

    5. 60 mil HDPE liner is the staple of the industry and is suitable for most applications.

    6. 80 mil HDPE liner is a thicker design for more aggressive subgrades.
