Balcony Waterproofing and Repairs from Building Services Australia

Commercial & residential multi-story balconies have been identified with an alarming frequency of building defects and a major reason being waterproofing problems.

Current construction methods are designed with balconies with minimal fall.

Balcony design with minimal fall has a significant effect on the choice of waterproofing product, installation method and tile adhesives used.

In such cases the waterproof membrane must be capable of "standing water".

Over time a balcony with minimal fall will have an increased likelihood of water ingress down through tile grout lines.

This leads to moisture "ponding" between the waterproof membrane and tiles.

Many membranes on the market today cannot withstand ponding water.

Accumulation of calcium salts, called "efflorescence, occurs on balcony surfaces only in the presence of water below.

Repairing leaking balconies may require complete strip out of existing tiles & membrane which may also involve major structural building works due to water damage of balcony infrastructure.
