Swellable Rubber Sealing Strips

BW water-swelling water stop takes import special rubber, inorganic water absorbent material, and high viscosity resin as main materials, produced through the process of mixing and extruding, it's designed on the basis of reference external product and the section shape is square strips with self-adhesion. It will swell gradually when contact with water, on the one hand, it can stop the water from the small holes, and on the other hand, it can make the contact with the concrete much more compact which can get a bigger hydraulic pressure resistance.
The product has a high expansion rate, strong mobile complement. Puts it into the construction joints, the next water stop has strong balancing and self-healing function, can self-sealing the small cracks because of the settlement. For finished project, if have any leakages, the water stop can be used for anti-leakage. This product has the advantage of low cost, simple construction and the best corrosion resistance.

Features

1. The water stop will swell when put into water.
2. Low expansion speed.
3. Simple construction and low price.
4. Non-toxic and pollution free.
5. No dissolved solid precipitation for long time soaking.
6. The biggest difference compare with other water stop is its expansibility still not loses after repeating and long term using.

Application

1. For waterproof sealing of shield construction of the tunnel segment joints.
2. For waterproof sealing of a variety of concrete, ceramics, plastics, steel, pipe bridges and culverts in the joints.
3. For waterproof sealing of underground engineering, foundation engineering deformation joints, construction joints, settlement joint, etc.
4. For waterproof sealing of reservoirs, dams, agriculture water conservancy facilities and hydropower construction.
