Product-type water stop strip

  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.

Steel edge water stop

  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 belt

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.

Grouting pipe type water stop strip

Our company combines engineering practice, and after repeated research experiments and extensive engineering applications, has recently launched a 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 to 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 using the water 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.

Water-swelling sealing ring

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.

A rubber steel edge water stop with a metal positioning component.

The rubber steel edge water stop belt is an embedded rubber water stop belt and is a commonly used form. The reason why the steel edge rubber water stop belt is widely used in deformation joints is that this material has good expansion deformation performance, especially the setting of holes on the steel edge rubber water stop belt, which increases the expansion deformation of the water stop belt when the main concrete structure settles unevenly. Therefore, it is very important to install holes on the water stop belt in the middle of the deformation joint. Currently, the rubber steel edge water stop belt is usually fixed with steel wire, but the problem with steel wire fixation during construction is that the water stop belt is prone to displacement during the concrete pouring process, causing the holes in the water stop belt to deviate from the deformation joint, failing to fully exert its excellent performance. From the above analysis, it can be seen that the existing rubber steel edge water stop belt lacks a rubber water stop belt that can remain stable and not shift during the subsequent concrete pouring process.

Application and Role of Rubber Waterstop in Engineering

The application and function of rubber water stop belts in engineering. Water stop belts utilize the high elasticity and compressive deformability of rubber to produce elastic stretching deformation under various loads. They are mainly used at joints and surrounding joints in underground foundations and tunnel engineering, serving to secure seals, prevent seepage and leakage, and ensure the service life of engineering structures.

Characteristics and Application Scope of Embedded Rubber Waterstop

Hebei Lifeng Rubber and Plastic Products Co., Ltd. explains what a buried rubber water stop is. The buried rubber water stop, also known as a central embedded rubber water stop or internal buried rubber water stop, is a type of water stop set within the concrete at deformation joints, expansion joints, etc. It has the ability to adapt to the expansion and contraction of concrete through the elasticity and structural form of the water stop material. From a structural perspective, it can be divided into two types: CB type water stop and CP type water stop.
