Tile Failure - Why does it happen?

Tile failure can prove extremely costly, typically requiring replacement of both tiles and substrate when conventional materials fail. With 12.5mm Aquapanel Indoor, tile or grout problems usually need only localised repair since water penetration does not compromise the backing board.

Tile failure occurs when moisture penetrates the substrate due to:

1. Water spills during plumbing installation
2. Unseen leaks in pipework within the wall
3. High-pressure water from power showers damaging grout and allowing water seepage
4. Condensation along pipework within the wall soaking into the substrate
