There are three types ofThere are three types of general soft waterproofing material: asphalt base waterproofing material, polymer modified asphalt base waterproofing material and polymer base waterproofing material.

So far, leakage is serious in our country, and it is urgent to enhance the quantity of waterproofing.The keys to solve problem are reasonable design, careful construct and in-time protection.What’s more, usually the tenet of waterproof uses rigidity and soft waterproof and defends on different coats.Waterproof material is developed in the directions of higher properties, multifunction with lower pollution.
