A common issue with leaking balconies; a lack or failure of the waterproof membrane, and poor execution. Note no upturn to the walls to protect this critical area.

​

Remedy: The only way to provide a long-term solution that satisfies the contractor's obligations under the Home Building Contract Act 1991 (HBCA), is to replace the waterproof membrane. Unfortunately this necessitates the replacement of all tiles.

​

Other methods such as clear sealing and grout replacement does not provide a long term solution and contravenes the HBCA.
