HDPE,LDPE waterproof membrane is made by the copolymer of ethylene--vinyl acetate, the copolymer of ethlene--vinyl acetate and asphlt and polyethlene. Meanwhile, the material of waterproof roll is mixed with antioxygen, age resisiter and other assistants that can be made through coextrusion and rolling.

HDPE waterproof roll has the advantages of low coefficient of permeability, uniform thickness, good environment stress crack resistance, good resistance to chemical corrosion,good resistance to deformation, good tolerance at different temperatures, good resistance to puncture.

ECB is applicabe to the various construction joints, waterproof of the tunnel liningand undergroud construction. It is also can be used alone as the drainning of blind drain. Meanwhile, it is very easy to be constructed, reduce the intensity of labor, save the raw material and so on.

HDPE waterproof roll is applicable to the hydraulic and hydroelectric construction, mining industry,environmental construction, underground construction and so on.

LDPE waterproof roll is applicable to the channel, garden, the roof covering, seepage-proofing construction and so on.
