Product Description
Swellable Water Stop Rubber Sealing Strip Water Swellable Hydrophilic Waterstop Strip
Swellable Water Stop Rubber Sealing Strip Water Swellable Hydrophilic Waterstop Strip
    Hydrophilic waterstop is a high-performance, water-swelling sealing strip made from hydrophilic rubber and inorganic water-absorbing compounds; upon contact with moisture it rapidly expands to fill concrete joints and cracks, achieving a "seal-by-water" effect. Widely used in construction, subway tunnels, underground galleries, pools and other wet environments, it offers high swelling ratio, self-healing capability, easy installation, environmental safety and long-term durability, and is available in putty, molded, self-adhesive and reinforced-mesh types in various sizes.

    Hydrophilic waterstop strip is a water-swellable waterproof sealing material installed in concrete construction joints and deformation joints. It maintains original size when dry and rapidly expands 2-3 times upon water contact, automatically filling gaps to form a dense waterproof barrier that prevents water infiltration. Ideal for underground projects and tunnels with long-term water exposure.

Functions
*Active Water Stopping: Automatically expands upon water contact to fill gaps
*Sealing: Post-expansion contact pressure ≥0.2MPa for effective water blocking
*Deformation Adaptation: Follows structural micro-movement while maintaining seal
*Self-healing: Minor damage recovers functionality after water contact
*Easy Installation: Pre-formed strips for quick installation
Product Features
*High Expansion Ratio: Volume expansion 200%-300%
*Adjustable Swelling Rate: Fast or slow swelling options per construction needs
*Strong Water Pressure Resistance: Withstands 0.6MPa water pressure without leakage
*Good Durability: Anti-aging with stable long-term performance
*Eco-friendly: Compliant with drinking water contact standards
Manufacturing Process
Key manufacturing processes include:
*Internal Mixing: Precise internal mixing of rubber, hydrophilic components, and various additives according to formulations.
*Compounding: Uniform mixing of all components through compounding processes.
*Extrusion: Formation of strips with square or other specified cross-sections from compounded rubber material.
*Vulcanization (for product type): Product-type waterstop strips undergo vulcanization to impart better elasticity and physical strength.
Product Advantages
    *Easy Installation: Self-adhesive or nail-fixed, no complex process required
    *Instant Effect: Expands on water contact for immediate waterproofing
    *Cost Effective: Economical pricing with high performance ratio
    *Strong Adaptability: Can fill irregular gaps
    *Fast Delivery: Regular specifications in stock
    *Flexible Customization: Customizable size and expansion ratio

Working Principle of Hydrophilic Waterstop Strip
Hydrophilic waterstop strips maintain a flexible, strip-like form when dry. Upon contact with water, they rapidly expand in volume (typically by 150% to 600%, with some products reaching up to 1000%). They compress to fill voids within concrete joints, forming a dense waterproof barrier that prevents water penetration.
