Waterproof board is a kind of impervious material which is made of high molecular polymer as the basic material. The physical and mechanical properties such as tensile,

tearing and breaking, can meet the requirements of the engineering design of water conservancy and chemical engineering, tunnel, transportation, etc, and can adapt to various working conditions, Products maximum width is 7 meters, has anti-aging, good durability, high coefficient of friction,corrosion resis tance, acid and alkali resistance, non-toxic，anti puncture strength and adapt to the characteristics of wide range of ambient temperature, in under the condition of - 50 degree to 100 degree cover can be used for more than 50 years,construction is convenient and reliable effect.
