Water-swelling waterstop strips, the models marked above, 3×2cm, 4×4cm, 3×5 are national standards, and 1.5×2.5mm is a common model.
The national standard water expansion rate is about twice its own, while the common model is slightly inferior.
If the above specifications do not have what you need, you can choose others and explain it in the remarks later.
Waterstop strips are made of a mixture of high-molecular inorganic water-absorbing and expanding materials and rubber. They are materials used to prevent leakage in construction joints of various underground construction projects, water conservancy projects, traffic tunnel projects, power plant cooling towers, municipal water supply and drainage and other concrete masonry projects.
About the installation of water-expanding waterstop strips:
1. When installing with a reserved pasting method, a groove for placing the upper waterstop strip should be reserved in the first poured concrete (wooden strips can be nailed in the template to reserve). After removing the first poured concrete template, clean the surface so that the joint surface is free of water, clean and free of debris.
2. Embed the waterstop strip in the reserved groove. If no groove is reserved, the vertical joint can be pasted with an adhesive for the entire length, or the waterstop strip can be fixed with cement nails and wooden strips; the horizontal joint can be directly pasted on 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 expanded by water to avoid affecting the use effect.
3. This product is pre-placed on the interface of concrete construction joints and post-casting joints. After the second pouring of concrete (i.e., when wrapped in concrete), it expands when exposed to water and can completely block and block the source of leakage. It has a high expansion ratio and strong mobility and supplementation. The waterstop strip placed in the construction joint and post-casting joint has a strong balance and self-healing function, and can automatically block new tiny cracks caused by settlement.
4. For completed projects, if there is water leakage in the gap, this waterstop strip can be used to re-block the leak. The waterproof and anti-seepage effects are better than traditional steel plates, rubber and plastic waterstops, and the construction method is simple and easy, saving labor and time. The main material is inorganic mineral raw materials, which have the characteristics of aging resistance, corrosion resistance, and pollution-free.
