High quality and cheap product type water expansion rubber waterproof strip

PZ rubber water stop is a new type of waterproof material that shares the same performance with ordinary rubber product and automatically expands by reacting to water. It’s more solid than common rubber water stop in terms of water stoppage and waterproof effect.

Features of product type water swelling rubber water stop strip:

1. After touching water, it will produce at least 1-5 times of the expansion deformation and fill all irregular surfaces of joints .Holes and gaps produce tremendous contact pressure at the same time to completely prevent leakage.

2. When the joints or the construction joints displacement cause the gap to exceed the elastic range of the material , ordinary rubber sealing material loses the sealing effect, but our product can achieve water stop by water swelling.

3. As plugging seal water stop material, water swelling rubber can save dosage and avoid general elastic material’s features of elastic fatigue due to excessive compression, which makes the waterproof effect more reliable with good water resistance, chemical resistance and aging resistance.

4. It is mainly used in shield construction method bricking joint waterproof, water stop strips used for building deformation joints and construction joints, and water stop of metal components and precast, concrete joints.
