Product Description
High Quality Water Swelling Waterstop Strip for Construction Joints
High Quality Water Swelling Waterstop Strip for Construction Joints
    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.
Material
    Made of modified natural rubber or polyurethane base with superabsorbent polymer (SAP) and additives. SAP absorption ratio ≥200% with no exudates after expansion. Non-toxic and eco-friendly, compliant with building material hygiene standards.
High Quality Water Swelling Waterstop Strip for Construction Joints
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
