Virgin ASTM Anti-Seepage Waterproof Impermeable Smooth Textured HDPE LDPE LLDPE PVC Geomembrane for Dam Pond Liner Landfill Mining

What is Geomembrane?
A geomembrane is very low permeability synthetic membrane liner or barrier used with any

geotechnical engineering related material so as to control fluid (liquid or gas) migration in a

human-made project structure or system.

Main Features of HDPE Geomembrane:
1.Excellent anti-seepage performance geomembrane has extremely low permeability and can effectively prevent the penetration of water and other liquids, thereby preventing seepage.
2.Good durability geomembrane has good anti-aging properties and chemical stability, and can be used for a long time in various harsh environments.
3.Convenient construction geomembrane has high flexibility and ductility, is easy to lay and connect, and construction is convenient and fast.
4.Economical and affordable geomembrane has a relatively low cost, long service life, low maintenance costs, and high cost performance.
