Why is your balcony leaking?

1. Wet weather conditions

Continuously being exposed to Australia’s harsh weather, your balcony is highly susceptible to water seepage. To avoid leaking, it needs proper drainage and as much protection from the elements as possible.

2. Natural building movement

Every building expands and contracts as it settles and reacts to the weather. This movement can crack tiles and grout lines. Once rainwater seeps into these gaps, it creates a breeding ground for mould that weakens the structure even more.
