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

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.
