Causes of leaking showers

Published : 05/03/2012

Why do showers leak and balconies leak?

The most common cause of leaking showers and leaking balconies is due to building movement and settlement causing weakening or cracking of grout, or the waterproof membrane under the tiles fails. This usually occurs between the floor and wall joints of the shower recess or balcony area.

Up to 90% of showers built onto a stud wall will eventually leak because a gap will occur between the tiled wall and the floor of the shower recess. This gap can be caused by the vibration of the wall arising from the opening and closing of doors and contraction and expansion of the wall as the building moves naturally from temperature and moisture changes.
 

Leaking showers and leaking balconies affect Australians everyday

The grouting between the tiles cannot withstand the vibration movements and the result is shower or balcony leakage via gap/s between the floors and walls.

  1. Solid brick homes can also experience the same problem as leakage can occur between the wall and floor due to expansion and contraction.
  2. Even showers with a shower tray/membrane can often only cope with small quantities of water, and are not equipped with self-drainage systems. Once the tray is full the overflow will leak into the floor and walls often being absorbed by woodwork and carpet in adjoining areas.
  3. As well as looking unsightly, these damp areas often smell, rot and attract white ants (termites).
  4. Silicones and "plugging" products may work for a limited period (depending on the quality of the product and the amount of leakage). However, efforts to remove dirt/mould build-up exacerbate the problem as few of the sealants are resistant to abrasive powder cleansers and/or scouring brushes.
    By preventing water from penetrating through the gaps and joins of the shower recess or balcony wall the Megasealed service provides a long-lasting, cost-effective solution.
