China National Petroleum Waterproof (Shenzhen) Co., Ltd.
JH-W200 PET Wet-Applied Waterproofing Membrane is a kind of cost-effective and environmental-friendly construction materials which contains adhesive materials and polyester (PET) film. The membrane has many advantages such as good adhesive strength, so it can be paved by both self-adhesive and wet-laid methods on the wet base surfacce.
1, The membrane can easily maintain its shape even in complicated base surfaces for its perfect adhesive strength.
2, Self-adhesive and wet-applied methods make the construction safe and environmental friendly.
3, Leakage rarely heppens even the membrane is broken for its good creep deformation abiliity.
4, The membrane can be used for temporary repairing in the steel roofing structure.
Wide usage in civil and industrial waterproof projects like basements and roofs, etc.
