Product introduction
Common name: Z water-swellable water-stop strip Product type water-swellable water-stop strip water-swellable rubber strip Z water-stop strip

Overview
The product-type water-swelling waterstop is a new type of waterproof material that has the performance of general rubber products and the ability to self-swell when exposed to water. The water-stopping and waterproofing effect is more reliable than ordinary rubber water-stop strips

Product-type water-swellable water-stop strips (Z or B) are produced using polymer expansion rubber technology and special processes. . It not only has good expansion properties, but also has the good elasticity and restoring force of general rubber. It undergoes elastic changes under external pressure and has an elastic water-stopping effect. The product has strong resistance to ions and has no leached matter and no pollution during the expansion process. It is repeatedly immersed in water and expands. It has good durability and dual effects of environmental protection. It is a material used to prevent leakage in the construction joints of various underground building construction projects, water conservancy projects, traffic tunnel projects, power plants, cooling towers, municipal water supply and drainage and other concrete construction projects

Main features
When the rubber comes into contact with water, it will expand and deform at least twice, filling all the irregular surface cavities and gaps of the joints and generating huge contact pressure to completely prevent leakage
B When the joints or construction joints are displaced, it will cause When the gap exceeds the elastic range of the material, ordinary rubber water-stopping materials lose their water-stopping effect, while this product can also stop water by swelling by absorbing water.
The use of water-swellable rubber as a leak-proof sealing and water-stopping material not only saves consumption, but also eliminates the elastic fatigue caused by excessive compression of general elastic materials, making the waterproofing effect more reliable. It has water resistance, chemical resistance and aging resistance. good.
It is mainly used in waterproofing of existing construction joints using the shield construction method, waterstops for construction joints of deformation joints in buildings, and waterproofing of joints of metal components, concrete prefabricated components.

How to use water stop strips
Reserved slot method: Leave a slot that can accommodate half of the rubber strip on the cement surface poured in advance and then embed the rubber strip into half of it. Continue pouring cement into the tank.
.Adhesion method: Position the glue waterstop along the installation line.
. Steel nails dense nailing method: Use steel nails to position the rubber strips along the installation line and the denser the steel nails, the better.
.The joints can be bonded with beveled surfaces or positioned with steel nails after being overlapped with bevelled surfaces.
Precautions for waterstop strips
The cement surface in contact with the rubber strip must be smooth and free of unevenness.
Since the specific gravity of the rubber strip is lighter than that of cement, the rubber strip must be firmly positioned during installation to prevent the strip from floating and misaligning, causing water leakage.
Do not leave a seam first and then insert the strips. The strips should be firmly fixed and embedded tightly and not exposed.
This product should not be exposed to the air for a long time and should be placed in a dry and ventilated warehouse to avoid exposure to strong light
