The water-expanding water-stopping strip not only has excellent expansion performance, but also has the characteristics that it does not disperse after being swollen, and is elastic, non-dissolved, anti-aging, corrosion-resistant, non-toxic and odorless, and is an ideal environmental protection waterproof material. This product also has the characteristics of excellent low temperature flexibility, plasticity and repeated immersion in water, not only to meet the general project of the water stop requirements but also to meet underground construction under harsh weather conditions.

1. After demolishing the concrete formwork, cut the construction joints, remove the floating joints on the interface with a wire brush, and apply a 2 to 5 mm thick grout. After the surface is dry, use a suitable adhesive or cement nail to fix the water stop. Pour the next ring of concrete.
2. The joints of water-expanding waterstops should be overlapped and overlapped and then fixed together to form a closed loop along the construction joints. No breakpoints are to be left between them.
3. After positioning the water stop, before pouring the next ring of concrete, try to avoid being soaked in water. If necessary, add a slow swelling agent to prevent it from expanding in advance.
4. When vibrating concrete, the vibrators must not contact the water stop.
5. When preparing the head plate, consideration should be given to the preparation of a shallow groove for the installation of a sealing strip.

Water expansion seal installation and construction suggestions:
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 water-free, 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 water-stops; horizontal seams can be directly bonded to concrete surfaces. After the sealing strip is pasted, the concrete should be poured as soon as possible. During the process of installation and installation, it should be prevented from being contaminated by water expansion seals and from being affected by water, so as to avoid the use of effects.
3. The product is preset on the interface of concrete construction joints and post-sealing joints. After the secondary pouring of concrete (ie, in the state of being wrapped by concrete), water swelling can completely block and block the leakage source. High expansion rate 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. Waterproof and impermeability are superior to traditional steel plate, rubber and plastic waterstops, and the construction method is simple, time-saving and labor-saving. The main material is inorganic mineral raw material, which has the characteristics of aging resistance, corrosion resistance, and no pollution.
