The water swelling rubber sealing ring has excellent characteristics and advantages. This type of rubber undergoes 2-3 times expansion deformation when exposed to water, and fills all irregular surface voids and gaps in the joints, while generating enormous contact pressure to completely prevent leakage. When the displacement of the joint or construction joint causes the gap to exceed the elastic range of the material, the ordinary rubber waterproofing material loses its waterproofing effect. This material can also stop water by absorbing water and expanding it. Using water swelling rubber as a sealing and sealing material not only saves usage, but also eliminates the characteristic of elastic fatigue caused by excessive compression in general elastic materials, making the waterproof effect more reliable.

When encountering water, the expansion rubber sealing ring will gradually expand. On the one hand, it will block the possible capillary pores, and on the other hand, it will make the contact between its concrete interface closer, resulting in greater water resistance pressure and forming an impermeable plastic colloid. This water stop product has a high expansion rate, strong mobility and replenishment, and is placed in construction joints. After pouring the joint, it has a strong balance and self-healing function, which can self seal new small gaps caused by settlement. For completed projects, if the gaps leak water, this water stop strip can be used to re seal the leakage. The use of this water stop strip is low-cost and the construction process is simple, with the best corrosion resistance.

Water swelling rubber ring, also known as water swelling water stop strip, is a type of water stop strip product made from more than ten materials such as imported special rubber, inorganic water absorbing materials, high viscosity resin, etc., which are mixed, squeezed and mixed together. It is a type of water stop strip with a cross section of square shaped self-adhesive water swelling type developed on the basis of foreign products. Relying on its own viscosity, it is directly pasted and pre-set at the interface of concrete construction joints and post pouring joints, and poured onto the secondary concrete.
