Leakmaster is a one-component swelling waterstop 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 water proofing seal for precast applications such as storage reservoirs and utility vaults.
