Leaking Balcony Repair in Brisbane

What balcony waterproofing in Brisbane actually involves

On a tiled balcony the usual entry points are a cracked or debonded grout line, a balustrade post fixed straight through the membrane, a drain outlet where the membrane was never dressed properly into the flange, and the junction where the floor meets the wall. Each of those is a different fix, and only one of them is resealing the surface.

What a leak repair actually involves

Tiles that sound hollow underfoot — drummy, in the trade term Brisbane operators use in their own consumer copy — mean the bed has lost its bond, which lets water sit under the tile rather than run off it. A white powdery bloom weeping from a joint is the same water carrying lime out of the bed as it evaporates. Both are visible long before anything appears downstairs.

Queensland Government guidance on building format plans states that where a balcony is included in a lot, "the boundary of the lot is the face of the balcony", and that a balcony outside those boundaries "would usually be the body corporate's responsibility". Critically, even on a balcony inside your lot, the body corporate remains responsible for "roofing membranes if the balcony provides protection to lots and common property below". In a Brisbane unit block that describes most balconies with anything underneath them, so it is worth settling before the repair is priced.

Leaking Balcony Repair in Brisbane — common questions

Why is water appearing on the ceiling below my balcony?

Because the ceiling is where the water finally exits, not where it entered. Water typically gets in through a grout line, a balustrade fixing or a drain flange, then travels along the fall of the slab until it reaches an edge. That is why sealing the visible stain does not stop the leak.

Do I pay for this, or does the body corporate?

It depends on the survey plan. Where the balcony is included in your lot, the lot boundary runs at the face of the balcony; where it sits beyond that face it is common property. The clause owners miss is that the membrane stays with the body corporate wherever the balcony shelters something below it.

What does drummy mean?

It means a tile has lost its bond to the bed underneath and sounds hollow when tapped. It is an Australian trade term, and Brisbane waterproofers use it in consumer-facing copy. A drummy tile lets water sit under the surface instead of draining off it.
