Water Swellable Bars

Water Swellable Bars are high-performance hydrophilic sealing products designed to prevent water ingress in concrete construction joints. These bars expand upon contact with water, forming a tight and durable seal that effectively blocks water pathways.

Commonly used in basements, tunnels, water tanks, sewage treatment plants, and retaining walls, water swellable bars provide a reliable, long-lasting waterproofing solution for construction and infrastructure projects.
