What’s Causing Your Balcony to Leak?

Have you ever wondered why your balcony is prone to leaks? In Sydney, the distinctive challenges your balcony encounters contribute to water seepage. Our solutions are ingeniously crafted with the specific challenges of our city in mind, ensuring effective protection against water-related issues.

1. Wet weather conditions

Continuously exposed to Sydney'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.
