- After the rubber encounters water, it will expand and deform at least 1-5 times and fill all the irregular surfaces of the joints. Holes and gaps, while generating huge contact pressure, completely prevent leakage.
- When the joints or construction joints are displaced, causing the gap to exceed the elastic range of the material, the ordinary rubber water-stopping material loses its water-stopping effect, and the product can also stop water by absorbing water and expanding.
- The use of water-swellable rubber as a leak-stopping and sealing material not only saves the amount of use, but also eliminates the characteristics of elastic fatigue caused by excessive compression of general elastic materials, making the waterproof effect more reliable, water resistance, chemical resistance and Good aging resistance.
- It is mainly used in the waterproofing of existing joints of shield construction method, deformation joints of buildings, waterstops for construction joints, and waterproofing of joints of metal components and prefabricated concrete components.
Uses: Product type water-swellable rubber waterstop, widely used in deformation joints, construction joints, waterproof sealing of through-filling pipelines of civil and architectural structures, joints of shielded reinforced concrete, waterproof gaskets, and interface materials for pipe jacking projects , Cut-and-cover method box culvert underground and level off the interface seal, water conservancy and hydropower, waterway civil engineering waterproof seal and so on.
Construction reference: Before pouring concrete, the expanded rubber should avoid contact with objects with moisture. Before construction, in order to make it contact with concrete reliably, the construction surface should be kept dry, clean, and the surface should be leveled.
