Product Introduction
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.
Scope and conditions of application
Before pouring concrete, the expansion rubber should be kept away from rain and contact with objects with moisture. In order to ensure reliable contact with the concrete before construction, the construction surface should be kept dry, clean, and flat.
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.
Product characteristics
• Reliable waterproof performance:
Once in contact with the invading water phase, its volume rapidly expands to achieve complete waterproofing.
• Safety of construction:
Due to its elasticity and resilience, it is easy to adapt to the deformation of structures.
• Applicability to wide surfaces:
Can be used in various climates and component conditions.
• Excellent environmental friendliness:
Chemical resistance, excellent durability, no harmful substances, and no environmental pollution

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.
Product-type water-absorbent swelling rubber 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, waterway civil engineering, etc.
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.
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.
