Leakmaster is a one-component swelling water stop sealant that, like Hydrotite, expands on contact with water. Prior to expansion, Leakmaster is suitable for bonding to a wide variety of substrates including concrete, rock and metals. Once applied, Leakmaster acts as high-performance waterproofing seal for precast applications such as storage reservoirs and utility vaults.

Used as a water stop in concrete construction joints requiring effective, economical protection against hydrostatic pressures up to 0.1 MPa (10 metre head of water).

Hydrotite CJ has been developed as an effective, simple and economical sealing material for site formed construction joints based on the proven effectiveness of Hydrotite.
