Hydrophilic Waterstop – Swelling Rubber Seal for Concrete Joints (Available in Mauritius)
Hydrophilic Waterstops are advanced swellable joint-sealing profiles designed to prevent water ingress through construction joints in concrete structures. When in contact with water, they expand to form a pressure-tight seal, stopping moisture migration. Ideal for below-grade and water-retaining structures like basements, foundations, tunnels, reservoirs, retaining walls, and lift pits. Available in two variants: TAL STOP HWS 520 and TAL STOP HWS 1020, with different thickness options. Perfect for tropical climates like Mauritius.
• TAL STOP HWS 520: 5 mm x 200 mm x 10 m roll
• TAL STOP HWS 1020: 10 mm x 200 mm x 10 m roll
Coverage depends on total construction joint length requiring protection.
