Leakmaster 320ml
Polyurethane Water-Swelling Sealant – Reliable Sealing for Concrete Joints
Description
Leakmaster LV-Z is a premium, one-component polyurethane water-swelling sealant designed for superior water sealing in civil engineering and construction applications. Supplied in a convenient 320ml cartridge, this gun-grade sealant is ideal for sealing around H-section steel posts, shotcrete joints, box culverts, pipe penetrations, and other challenging surfaces where traditional sealants fail.
Engineered for durability, Leakmaster supports up to a 20m head of water and swells approximately twice its original volume upon contact with moisture, ensuring a watertight seal even under extreme conditions. After curing, it delivers rubber-like elasticity and exceptional physical properties, outperforming conventional putty-type sealants.
Perfect for tunnels, basements, pits, and water service structures, Leakmaster provides long-lasting protection against water ingress. Easy to apply with standard caulking guns, it offers reliable performance for complex joints and penetrations, reducing maintenance and enhancing structural integrity.
