High swelling Hydrophilic Bentonite Waterstop for sealing working joints


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.

Note: 1) Hardness is recommended item

2) Silicone test of finished products achieve 80% of the standard.

3)The tensile strength targets in joints shall not less than 50%of the standard.



Purpose

The product type water swelling rubber water stop strips are widely used in waterproof sealing of deformation joints and filling pipelines of civil building structures, the joints of steel reinforced concrete by shield construction method, waterproof sealing pads, the interface material of pipe jacking engineering, interface seal of open excavation method box culvert underground pipeline, water conservancy and hydropower engineering, waterway civil engineering , water-proof packing and so on.

Construction reference matters: before pouring concrete, expansion rubber should avoid rain and contact with objects with water. For the reliable contact with the concrete before construction, construction level should be kept dry and clean, and the surface should be flattened.

Note: According to design requirements, we can also make slow swelling type water swelling rubber water stop strips.
