How HydroHalt addresses three of the most frequent causes of joint seal failure around shower trays and baths.

Problem 1: The sealant bridge between the wall tile and ledge splits under the effects of joint expansion and the joint leaks. Joint sealant bridging the tile and ledge cannot be relied upon to remain waterproof without periodic inspection, maintenance and replacement to prevent consequential damage. For this reason the joint itself is often referred to as a ‘maintenance joint’. Unfortunately, in many cases it is the notice of a leak that instigates joint inspection at which time it is already too late because the damage is done!

Solution: Don’t rely on exposed joint sealant between the tile and ledge as the exclusive means of waterproofing the joint. Install Sealux HydroHalt as a permanent secondary movement joint seal behind the exposed tile/ledge joint sealant.

Problem 2: Joint sealant between the tile and ledge naturally deteriorates under frequent exposure to the chemicals and physical weathering in modern shower environments. Sealant deterioration is another cause leaks.

Solution: HydroHalt is designed to conceal and protect the silicone from direct exposure to the deteriorating effects shower environments. Once installed, HydroHalt delivers a permanent watertight maintenance-free joint seal.

Problem 3: Under the effects of joint expansion, sealant between the tile and ledge can suffer a loss of adhesion with the ledge or tile resulting in water leaks and wicking.

Solution: The Sealux strip has a red tinged surface specially primed for tenacious adhesion with Sealux-N silicone. When HydroHalt is installed to seal a bath or shower tray with or without a tile flange, tenacious adhesion between strip and silicone, flexibility in the Sealux-N silicone and elasticity in the Sealux strip collectively accommodate the joint expansion and maintain seal integrity.

Conclusion: Installing HydroHalt as a permanent secondary concealed movement joint seal behind the exposed tile/ledge joint sealant ensures that when the sealant joint between the tile and ledge fails, the resulting leak is contained inside the shower area.
