The waterstop is made of polymer inorganic water-absorbing and swelling materials and rubber. It is a variety of underground construction projects, water conservancy projects, traffic tunnel projects, power plant cooling towers, municipal water supply and drainage and other concrete construction joints to prevent leakage. material.
About water expansion seal installation should:
1, in the installation of a reservation-style paste method, in the pre-concrete must be reserved on the water stop slot (in the template can be nailed sticks reserved). After removing the pre-watered concrete formwork, remove the surface so that the joint surface is free of water, clean, and free of debris.
2. Insert the water stop in the reserved slot. If you do not reserve slots, you can add full-length adhesives to vertical seams, or use concrete nails and wood strips to fix the sealing strips. Horizontal seams can be directly bonded to concrete surfaces. After the sealing strip is pasted, concrete should be poured as soon as possible. In the process of installation and adhesion, it should be prevented from being contaminated by water expansion seals and the effect of water expansion, so as not to affect the effect of use.
3. The product is pre-set on the interface of concrete construction joints and post-sealing joints. After the secondary pouring of concrete (that is, in the state of being wrapped by concrete), water swelling can completely block and block the leakage source. High expansion ratio and strong mobility. The sealing strips placed in the construction joints and the post-sealing joints have a strong self-healing function and can block the new micro-cracks that occur due to settlement.
4. For the completed project, if the gap leaks water, the water stop can be used to stop the leakage. The waterproof and impervious effects are better than traditional steel plates, rubber and plastic waterstops, and the construction method is simple, time-saving and time-saving. The main material is inorganic mineral raw material, which has the characteristics of aging resistance, corrosion resistance, and no pollution.
