Putty type water stop strip is made of polymer inorganic Made of water-absorbing expansion materials mixed with rubber, it is a material used to prevent leakage in construction joints of concrete construction projects such as underground construction projects, water conservancy projects, traffic tunnel projects, power plant cooling towers, municipal water supply and drainage, etc.
& Products Performance
This product is a gray-black putty-like colloid, which has the characteristics of good weather resistance, anti-aging, anti-leakage, corrosion resistance, easy operation, and low cost.
Main uses
(B) Waterstop strips are used to prevent leakage in construction joints of various reinforced concrete projects such as underground building construction projects, water conservancy projects, traffic tunnel projects, power plant cooling towers, municipal water supply and drainage, etc. This kind of material completely solves the problem that rubber and steel waterstops are prone to leakage due to friction.
Product Features of Waterstop Strip
This product has the ability to swell when immersed in water. The effect of water-stopping is to have a slow expansion rate. When immersed in water, its expansion rate & expansion rate is %. This product is easy to install and construct, and is cheap. It is non-toxic and non-polluting, and has no dissolved matter precipitation under long-term immersion in water. Compared with other hydrophilic swelling waterstops, its hydrophilic swelling properties have not been lost after long-term repeated expansion.
Quality Standards
. The surface of water-swellable rubber should be clean and smooth, without scratches, bubbles and other impurities, and the edges should be neat. b. Tensile strength &.. Elongation at break (%) & hardness (Shore) (degree). Hydrostatic expansion rate %&.
The principle of appropriate thickness should be followed in the design of water stop strips. Some design departments believe that when using water-swelling waterstops, the thicker the better. In fact, this design concept is wrong, because when using thick waterstops, it is easy to cause the concrete to be poured loosely. Once the concrete is poured, it will not be tight. If so, there will be a serious risk of water leakage in the future, so it is recommended to use the most appropriate size.
Putty type water-swellable waterstop strip
Common names: water-swellable waterstop strip, B water-swellable waterstop strip, water-stop rubber strip, water-swellable rubber strip
Putty type Water-swellable water-stop strips are also called putty-type water-swellable rubber water-stop strips. It is a strip sealing material with water-swelling properties made of more than ten kinds of materials through dense scouring, kneading and extrusion.
Putty-type water-swellable waterstops have a high expansion ratio and strong mobility. They have a strong balance and self-healing function after being placed in construction joints. They can self-block new micro-cracks caused by settlement. For completed projects, if water leaks from gaps, the water stop strip can be used to re-block the leaks. The water stop strip has low cost, simple construction process and corrosion resistance. It is widely used in construction joints, expansion joints and cracks in civil air defense, swimming pools, sewage treatment projects, underground railways, tunnels, culverts, etc. and other concrete projects.

br/> Compared with other hydrophilic swelling waterstops, its hydrophilic swelling properties have not been lost after long-term repeated expansion.
Recommended construction techniques
⑴ For the reserved pasting method, a groove for the water stop strip must be reserved in the first poured concrete (wooden strips can be nailed into the formwork to reserve).
⑵ After removing the pre-poured concrete formwork, clean the surface to make the joint surface water-free, clean and free of debris.
⑶Insert the water stop strip into the reserved groove. If no grooves are reserved, adhesive can be used to stick the entire length of vertical joints, or waterstop strips can be fixed with cement nails and wooden strips. Horizontal joints can be directly attached to the concrete surface.
Concrete should be poured as soon as possible after the waterstop strip is pasted.
During the installation and pasting process, the waterstop strip should be prevented from being contaminated and exposed to water, so as not to affect the use effect.
Product-type water-swellable water-stop strip
Product introduction
Product-type water-swellable water-stop strip (Z or B) This product is produced using polymer expansion rubber technology and special processes. become. It not only has good expansion properties, but also has good elasticity and restoring force of general rubber. It undergoes elastic changes under the action of external pressure and has elastic water-stopping effect. The product has strong ion resistance and no dissolved matter during the expansion process. It is pollution-free, has good swelling properties after repeated immersion in water, and has dual effects of being permanent and environmentally friendly
