Water swellable rubber is made of rubber with water soluble polymer materials in water by mixing the processed product. That is a general characteristic of rubber products, and water self expansion to water seal function. Sealing and waterproof effect against the material has the elastic joint sealing material, when the joints on both sides of the distance to increase the elastic waterproof material elastic recovery rate below, because the material has the characteristics of water swellable materials, in the range from expansive water stop, the expansion body has more rubber properties, water resistance, acid and alkali resistance.
Excellent waterproof seal
Such as the use of water swellable rubber, when water seeping into the end, can rely on their own water swelling pressure, compaction of concrete structures, and the pipeline of the bolt gap, blocking the leakage passage, to achieve permanent waterproof effect.
Water swellable rubber is a kind of waterproof material excellent in the majority of members of the design and construction of support and recommendation, over the years, since the waterproof structure of the underground engineering of the reinforced concrete material has been widely used in various categories, its good flexibility, extensibility and expansion of water has been renowned throughout the country. The water resistance of the material with excellent resistance to chemical durability and weather resistance has been the night service of underground shopping malls, underground garage, underground water diversion project, open caisson, confirmed by the flood wall and many other projects.
