Rubber waterproof belts are mainly used in concrete pouring when placed in construction seams and deformation seams to become a single foundation engineering with concrete structures, such as underground facilities, tunnel coverings, conveying water tanks, blocking dams, storing liquid buildings etc. Rubber waterproof belts are mainly used in concrete pouring when placed in construction seams and deformation seams to become a single foundation engineering with concrete structures, such as underground facilities, tunnel coverings, conveying water tanks, block
