Product Details

Advantage:

1. It is of layer-construction, the surface layer is of strengthening protection, the second of ageing resistance, the third of waterproof and the beneath of strengthening adhesion. Every layer has special features which greatly improves the comprehensive function of the product.
2. Layer of ageing-resistance make it have long service life up to 50 years; Two layers of coarse non-woven cloth for strengthening protection and adhesion make it have big coefficient of friction and easy to bond firmly with various adhesives;
3. It is a kind of no poison, no pollution and environmental product.
4. High tensile strength, strong anti-permeability and good cold flexibility.
5. It can be applied only if there is no obvious water in the field.
6. It can be directly used in the cement construction and sandy soil, etc. And the surface of the membrane can be directly decorated by ceramics, etc.;
