Our company combines engineering practice, and after repeated research experiments and extensive engineering applications, has recently launched the water-swelling waterproof strip for grouting pipes. This product transforms the concept of grouting remediation into reality based on the waterproof principle of the swelling strip. Compared with previous products, this product has advantages such as easy installation, reasonable price, and better waterproofing effect. Especially with the installation of pre-reserved grouting pipes as a remedial measure, in case of leakage at the seams, there is no need to groove or drill holes on the structural surface for sealing; the grouting liquid can be directly injected into the grouting pipe of the waterproof strip, quickly and conveniently sealing the leakage. Particularly, the application of chemical grouting materials, after selection and adjustment, can cure and solidify in both dry and wet conditions of concrete structures, resulting in a solidified body with excellent mechanical properties and impermeability that meet the requirements for crack reinforcement. This has solved a series of engineering technical problems in the leakage repair operations of concrete projects, demonstrating unique effectiveness and achieving significant social and economic benefits.

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.
