Hydrophilic Rubber 10x20mm

Hydrophilic Rubber Waterstop 10mm x 20mm is a durable, medium-profile sealing strip designed to expand when exposed to water, providing robust waterproofing for static concrete joints. Its innovative dual-layer design combines an outer hydrophilic rubber that swells upon hydration with a non-expanding internal rubber core that controls and stabilises expansion.

This size is ideal for general-purpose joint sealing in both vertical and horizontal applications. The waterstop activates on contact with moisture, creating a pressure-tight seal that prevents water ingress. Thanks to its self-adhesive backing, installation is clean and efficient—just apply to the prepared surface before the concrete pour.

Commonly used in:

• Underground structures and utility vaults
• Water tanks, towers, and reservoirs
• Pipe penetrations and tunnel joints
• Sewerage and treatment plants
• General horizontal and vertical construction joints

Engineered for performance, this hydrophilic waterstop ensures dependable protection in water-sensitive environments.
