PVC Waterproof Membrane Property
1) Excellent aging resistance.
2) Root resistant penetration, specially used on planting roof.
3) Welding installation. Joints are solid and environment friendly, no pollution.
4) High tensile strength, good elongation and dimensional stability.
5) Good plasticity, easy and suitable for details installation.
6) Fireproof. Fire extinguished out of the ignition resource.
7) Surface is smooth, no fading and dirty resistant.
PVC Waterproof Membrane Application
--All kinds of roofs, such as steel structure roof, planted roof etc.
--Underground engineering, such as building basement, subways, tunnels, air raid shelter, etc.
--Other projects like artificial lake, dam, water reservoir, grain storehouse, etc.
