Steel edge water stop belt production process technology
The steel edge rubber water stop belt is a composite made of generally stretchable rubber with galvanized steel edges on both sides. This water stop belt mainly relies on the rubber section in the middle being compressed or stretched between concrete deformation joints to achieve a sealing and water-stopping effect. Generally speaking, the adhesion between concrete and rubber is poor, and during conventional construction, the rubber, being a soft elastic body, makes it difficult for the concrete to be compacted during pouring. Therefore, when the concrete joints expand, pull apart, or twist, the rubber water stop belt often becomes loose and falls off, leading to leakage under high water pressure. This issue is even more pronounced for joints with large deformation gaps.
