30% material, 70% installation and that's where the success lies.Leakage in a project can occur even with premium rubber waterstops, poor installation practice will cause project leakage. Here are 3 important steps to take when working on-site construction:
- Zero Displacement, Secure Fixation: While concrete is being poured, the waterstop must be securely attached to the steel rebar cage with special fixtures or flat steel bars. Do not punch holes through the body of the waterstop for wire tying, as this will compromise the waterstop's waterproofing integrity.
- Center Alignment The center bulb of the waterstop shall be aligned exactly with the center of the concrete deformation joint. This positioning allows the bulb to extend properly and accommodate maximum movement.
- Hot-Vulcanized Joint Splicing: Simple overlapping at joints is strictly prohibited. The field joints shall be fused by professional electric heating vulcanization molds, so that the rubber can be blended into a single cohesive piece, and the joint strength shall reach not less than 80% of the parent material.
