Certification: ISO
Surface: Smooth Side
Application: Transportation Project
Feature: Puncture Resistance
Material: HDPE
Color: Black

Product Description

· HDPE Smooth Geomembrane is a new material that can be waterproof and barrier-proof. It mainly uses high-density polyethylene resin and is added carbon black, antioxidant, anti-aging and UV-resistance component to have excellent environmental stress crack resistance, low temperature resistance, aging resistance, corrosion resistance and large service temperature and long service life.

·High mechanical strength: Good physical and mechanic performance.
·Chemical resistance: Good waterproof, drainage, anti-seepage and damp proof effects.
·low permeability: High tearing resistance, strong deformation adaptability.
·Anti-aging performance: Good adaptability to high and low temperature, non-toxicity, long service life.

Product use:
(1) landfill and sewage or waste disposal.
(2)lake dam, tailings DAMS, sewage dam and reservoir, irrigation channels and liquid storage pool, mine (pit).
(3)subway, basement, tunnel and tunnel lining seepage control.
(4)roadbed and other foundations in brine seepage control
