Water Swellable Bar

Water Swellable Bars are specially engineered hydrophilic sealing products designed to prevent water leakage through construction joints in concrete structures. When exposed to water, these bars swell and expand, forming a tight and effective waterproof seal within the joint.

Widely used in basements, tunnels, water tanks, retaining walls, sewage treatment plants, and underground structures, water swellable bars provide long-lasting protection against water ingress and enhance the durability of concrete constructions.
