Leakmaster Waterstop Sealant

Hydrotite Leakmaster is a gun-applied, single component expanding sealant that exhibits excellent swelling and sealing properties in its cured state. It retains a rubber-like elasticity to maintain an effective watertight seal throughout its life. Once applied, Leakmaster acts as high-performance water proofing seal for a range of applications such as storage reservoirs and utility vaults.
Benefits

Why use Pozament Leakmaster Waterstop Sealant?

Leakmaster was developed using the same hydrophilic compounds found in our Hydrotite range of rubber waterstops. After hardening, Hydrotite Leakmaster sealant swells on contact with water to almost twice its original volume.
Intended for use in gaps, irregular joints and in pipe and beam penetrations, Hydrotite Leakmaster sealant is applied easily and accurately using a standard caulking gun.
Hydrotite Leakmaster sealant can be used with a wide range of materials including concrete, steel, glass, mortar and brickwork.
