Water-Swelling Waterstop Strip

• Active Swelling Seal: Relies on the material's inherent hydrophilic properties to expand several times its original volume upon water contact, self-adapting to fill gaps and achieving an active, persistent sealing effect.

• High Fillability & Conformability: Offers good flexibility and plasticity, conforming to irregular substrates. It is particularly effective for sealing complex areas like construction joints, cold joints, and around penetrating pipes.

• Durability Design: High-quality formulations ensure stable expanded structure and performance in long-term damp environments, with resistance to hydrolysis and minimal degradation.

• Easy Installation:The product is supplied as a flexible strip, which can be easily cut to the required length on-site, offering flexibility during installation.

  
  

The water-swelling waterstop strip primarily relies on its expansion upon water contact to fill concrete joints and form a seal. Its typical applications span the following engineering fields:

• Underground Engineering: e.g., construction joints and cold joints in subway tunnels, basements, and civil air defense projects.

• Water Conservancy Engineering: Used for joints in concrete structures such as reservoirs, water tanks, and sewage treatment plants.

• Transportation & Industrial Construction: Suitable for bridge and tunnel joints, as well as sealing around penetrating pipes and crack repair in buildings.

Customization Note:The above are typical parameters. All specifications and product dimensions can be adjusted and customized according to your project drawings and technical requirements.

• What is the main difference between a water-swelling waterstop strip and a standard waterstop?

The core difference lies in the working principle. Standard waterstops (e.g., rubber or PVC) rely on material elasticity to passively accommodate joint movement. In contrast, the water-swelling strip actively expands upon water contact to seal gaps through physical filling.

• What are the requirements for storage and transportation?

The product should be stored indoors in a dry, cool, and ventilated environment, protected from direct sunlight, high-temperature heat sources, and moisture. During transportation, protect it from heavy compression and sharp objects to keep the packaging intact.

• What other products does your company offer besides water-swelling waterstop strips?

As an integrated solutions provider, our product line also includes: waterstops, bridge laminated elastomeric bearings, rubber bearing pads, pot bearings, spherical bearings, seismic isolation bearings, bridge expansion joints, as well as sealants (polyurethane, polysulfide) and building seismic isolation flexible pipelines. We are committed to supplying a range of critical components for civil engineering.

• Is there a quality guarantee for the products?

Yes. We provide a quality guarantee for our finished products. Strict control standards are implemented at every stage, from raw material procurement to manufacturing, to ensure product performance meets technical specifications.

• What management system certifications does your company hold?

Our company has established and maintains integrated management systems, and is certified to Quality Management System (e.g., ISO 9001), Environmental Management System (e.g., ISO 14001), and Occupational Health & Safety Management System (e.g., ISO 45001) standards.
