Waterstop for Construction
This advanced composite waterstop is engineered for critical construction joints, delivering superior long-term waterproofing. It combines the high tensile strength and durability of PVC with the exceptional flexibility and weather resistance of neoprene and natural rubber. Ideal for foundations, tunnels, reservoirs, and water treatment plants, it effectively withstands high hydrostatic pressure, movement, and harsh environmental conditions. Its robust design ensures a permanent, watertight seal in concrete structures, providing reliable protection against water ingress. H
