Although showers, shower baths or balconies may leak due to a number of reasons, the most common cause of seal leakage is building movement, i.e. as a building settles into it’s foundations or moves naturally with hot and cold weather. This movement can result in weakening or cracking of grout, seal, tile and floor/wall junctions within the shower, bath or balcony. This eventually allows water to penetrate beneath the surface of the tiles.

Waterproof Membrane Fails are another cause for seal leakage. Beneath the surface of the tiles there is usually some kind of waterproofing membrane designed to prevent water penetrating the surrounding areas. Unfortunately these sealing membranes are also susceptible to building movement, poor installation and chemical breakdown with age. Once this membrane has been breached, water is free to penetrate into the surrounding areas and cause damage.
