Product Description

Application：

Rubber water-proof belt is generallt used in large concrete construction such as dam, reservoir and basement etc. Rubber water-proof belt is poured in deformation joint and construction joint of these project to avoid leakage.

Physical and mechanical property of rubber should accord with requirement listed below:
