Product
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 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 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.

Product type water absorbing and expanding rubber is widely used in deformation joints, construction joints, waterproof sealing of pipelines in civil and architectural structures, joints of reinforced concrete in shield tunneling methods, waterproof sealing gaskets, interface materials for pipe jacking projects, interface sealing of underground pipelines in open cut box culverts, waterproof sealing of water conservancy, hydropower, waterway civil engineering, etc.
The back-adhesive rubber water stop is a water-stopping structure set on the outside of the concrete deformation joints and settlement joints of underground structures (water-facing surface).
Good wear resistance and aging resistance: It can maintain stable performance even after long-term use.
High elasticity: Able to adapt to the expansion and contraction of concrete, ensuring water stop effect.

The water-swelling sealing ring (sheet) is a new product recommended by our company after repeated experiments for the concrete formwork tie bolt project. The water-swelling rubber sealing ring for tie bolts is a new type of waterproof engineering material. It can absorb water and expand upon contact with water, sealing the gaps between the concrete and the tie bolts through its own expansion, effectively preventing water leakage. In actual construction, it is flexible and convenient to operate, saving labor and time. It is an upgraded product of welded sealing plates (rings). Currently, the concrete formwork tie bolt sealing ring has been applied in various projects. The water-swelling sealing ring is made of water-swelling rubber, and its performance meets the indicators specified in GB/T18173-2002 "Polymeric Waterproof Materials" Part 3: Water-Swelling Rubber. When in use, simply fit the sealing ring tightly onto the tie bolt or the bar-type tie rod.
Two-component polysulfide sealant (adhesive)
Two-component polysulfide sealant is made of liquid polysulfide rubber as the main material, combined with tackifying resin, curing agents, accelerators, reinforcing agents, and other components to create the sealant. This type of sealant has excellent resistance to fuel, hydraulic oil, water, and various chemicals, as well as heat resistance and atmospheric aging resistance. Generally, it is a curable type. It can be divided into two-component (or three-component) and single-component types based on components. Its processing uses a pre-mixing - grinding - filling method. Two-component polysulfide sealant is a leading waterproof material both internationally and domestically. In developed countries abroad, mid-rise buildings use polysulfide construction paste for wall joint sealing. Polysulfide waterproof sealant is suitable for long-term submerged building joint sealing, with good adhesion to concrete, such as: underground waterproof joints, aircraft runways, water storage tanks, sewage pools, underground projects, and large-scale water conservancy projects all use polysulfide sealant. It has aging resistance, durability, air tightness, and waterproofing properties, with good adhesion and high elongation rubber shape high elasticity. Domestically, this product has been used in some large reservoirs, water storage tanks, sewage pools, and underground projects, receiving high praise from engineering technicians.
The new type of water-swelling sealing strip with mesh is a new waterproof sealing material developed and produced by our company to address the shortcomings of ordinary sealing strips with low tensile strength.
