Features

Spunbonded polyester fiber membrane--integrated advantage properties of spunbonded polyester substrates and APP modified asphalt, wonderful integrated properties.

It could form a waterproof layer, which has high strength and good property to stand against water pressure

High tensile strength and elongation rate, strong adaptability for substrate shrinking distortion and cracks

Good resistance to low temperature, corrosion, mildew and weathering

Large thickness of PY fiber enables the products quite resistant to puncture, pressing, rubbing, tearing, and wearing                     

Good construction performance, with firm and enduring joints

No alkali glass fiber membrane--pretty high tensile strength, wonderful high and low temperature resistance, resistance to damnification, corrosion, mildew and weathering, good construction performance

Applied Range

It could be widely used in all kinds of waterproof engineering projects in all fields, especially in the following types of engineering projects

All kinds of building roof engineering projects, treading, non-treading, heat preservation, non-heat preservation, planting building surfaces, roof parking lots, and converted building surfaces

All kinds of underground waterproof or dampproof engineering projects

Bridge surfaces of subways, tunnels, concrete roads, sewage treatment, garbage burying projects and other municipal engineering waterproof projects

Water spraying pools, swimming pools, penstocks, water pools, and so on.
