Tile Failure - Why does it happen?

Tile failure creates significant expense, typically requiring complete replacement of both tiles and substrate when standard materials fail. With Aquapanel Indoor, tile or grout problems usually need only targeted repairs since the board resists water damage and substrate deterioration.

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
