Description HDPE Geomembrane is called”High Density Polyethylene membrane”,which is made out of High Density Polyethylene,compund with carbon,anti-aging agent, antioxidantm, stabilizer and etc,proceed by Multi-layer coextrusion technology.It is specially designed for underground engineering constructions with international advanced technology, it can bind the later cast concrete form a firm structure.

-Low density polyethylene Geomembrane(LDPE)
-High density polyethylene membrane(HDPE)and EVA
-Specification: Width:2m or customized

Feature (1)Long service life:it has excellent resistance of degrading ability and impermeability,
especially HDPE geomembrane has excellent anti-ageing and anti-ultraviolet,could be used outside,the material has long life and provide a good assurance for seepage control.
(2)Strong chemical resistance, resistant to alkali water from concrete, resistant to household refuse and organism, mould resistant and corrosion resistant. 
(3)Good flexibility:various laying method could satisify different construction requirement, hot melting is availabl,the welding seam has good strength,easy construction,quick and environmental protection
(4)Excellent impermeability:the seepage coefficient is lower than clay with 4-5 magnitude order.
