Why do Showers leak?
During construction a waterproof membrane must be applied to the substrate whether it is concrete compressed fibro or construction grade plywood. Inexperienced waterproofers fail when it comes to delegating the appropriate products for the area to be sealed. Also neglected is the necessary detailing in a waterproof system which in time leads to the waterproof membrane failing due to the smallest amount of building movement whether it be from settlement or hot and cold weather. This is how the leaking shower begins.
Another cause of a leaking shower is that certain membranes have little or zero tolerance to cleaning chemicals, which in time is also known to break them down and cause the membrane fail.

Signs that your shower is leaking…
- Swelling skirting boards
- Dampness or mould build up
- Peeling paint on ceiling, bathroom or outside wall
- Damp musty smell
- Wet carpet
- Stained timber under the sub floor
- Cracked tiles
