We can produce various specifications of Swelling waterstop strip according to the customers requirements.

Description of Swelling waterstop strip

Swelling waterstop strip is a new type of water stop check of aquatic products, it passes through vulcanization molding, but unlike general rubber products, it has excellent resilience, extensibility. And elastic seal water. It can meet water expansion, with water water stop, stop water effect to make it more reliable than ordinary waterproof materials.

Advantages of Swelling waterstop strip:

1. It can resist hydrostatic pressures of up to 80 meters of water column= 8 bar

2. The durability and performance of the bentonite water-stop will exceed the design life of the structure (bentonite is a product of nature)

3. The highly elastic and plastic properties of bentonite water-stop will easily counterbalance the initial concrete shrinkage of the structure.

4. Can fill small honeycombs

5. Will not dissolve in water and is non-polluting
