Problems solved by technology

[0004] 1. During the construction of SBS coiled material, it cannot be closely adhered to the base surface concrete, and the joint room between the coiled materials is a weak link, and a little carelessness will cause the failure of the entire waterproof system; secondly, once the water penetrates and breaks through the cement mortar protective layer , after long-term contact with the sbs membrane as a rubber asphalt waterproof membrane, it may cause pollution to the quality of drinking water, so a thick ceme
