Product Introduction
The main performance indicators of the water swelling waterstop produced by our company have been tested and qualified by the National Building Materials Testing Center and Beijing Building Materials Science Research, and have reached the performance of similar foreign products. This product is a chemical building waterproof material processed from more than ten materials such as advanced absorbent materials and rubber, mainly used to solve the problem of water leakage in underground concrete construction joints.
Scope and conditions of application
This product can be used in concrete construction joints of underground buildings, effectively and thoroughly solving the problem of water leakage in construction joints. It is an ideal waterproof product widely used in various projects such as basements, caverns, mines, bridges, tunnels, subways, sewage treatment plants, dams, water storage tanks, etc.
Performance advantages
When encountering water, it expands and stops with water. Used for defecation and maintaining a state of water absorption and expansion in humans. Not shrinking, not losing water, durable and reliable, and has the characteristics of no competition, no corrosiveness, no pollution, convenient and fast construction, reliable quality, labor-saving, time-saving, and low cost.
Usage method
After the completion of the previous section of concrete pouring and the hardening and surface drying of the construction joint interface, remove the interface floating slag, and attach the water stop strip along the direction of the construction joint extension to the construction joint interface. The vertical construction joint can be fixed with steel nails to prevent displacement. When connecting, the water stop strip can be attached laterally and tied firmly with lead wire, and then the next section of construction can be carried out.

The main performance indicators of the water-swelling water stop strip produced by our company have been tested and qualified by the National Building Materials Testing Center and the Beijing Building Materials Science Research and Testing Institute, and have reached the performance of similar foreign products. This product is a chemical building waterproof material made from more than a dozen materials, including high-grade water-absorbing materials and rubber, mainly aimed at solving the problem of water leakage in construction joints of underground concrete.
The water-swelling waterproof strip is widely used in deformation joints, construction joints, waterproof sealing of penetrating pipelines in civil engineering structures, joints of reinforced concrete in shield tunneling, waterproof sealing gaskets, interface materials for pipe jacking projects, sealing of interface for underground pipelines in open-cut box culverts, and waterproof sealing in hydraulic and hydropower engineering, as well as in waterway civil engineering.
The steel edge rubber water stop (also known as: steel edge water stop) is a rubber water stop with a non-uniform thickness structure in its cross-section. The steel edge water stop is divided into a strong area and a waterproof area. Installation holes are added to the steel plate of the water stop and connected to the rebar, making it difficult to displace after being fixed, ensuring that the stress on each part is uniform and reasonable. It has characteristics such as high strength, good elasticity, easy fixation (can be welded to the rebar for fixation), and strong bonding with concrete. However, it has a small elongation rate and poor resistance to bending deformation, making it unsuitable for areas with frequent changes in joint width.
Rubber water stop is made using the high elasticity and good compressive deformation of rubber, as well as its high tear strength and tensile strength, to produce elastic deformation under various loads without tearing or breaking, thus serving the purpose of securing seals, preventing seepage, and preventing leaks.
