North Sydney Waterproofing
In North Sydney’s dense urban environment, waterproofing is essential for both residential towers and commercial infrastructure. With limited space between buildings, complex drainage systems and exposure to varying wind and rain conditions, even minor water ingress can cause significant disruption.
Structural leaks not only compromise building integrity but can also impact electrical systems, finishes and liveable spaces—particularly in multi-storey environments. Effective waterproofing creates a barrier against these risks, using tailored systems applied at the right time and in the right location. Whether you’re overseeing a new high-rise, managing a strata building or renovating a heritage site, our team ensures every detail is sealed to spec. At Legend Waterproofing, we bring precision, reliability and decades of experience to projects of all sizes.

Frequently Asked Questions
How does high-rise construction impact waterproofing needs?
High-rise structures experience greater wind load, movement and exposure to rain. Waterproofing must be more flexible and durable to accommodate these stresses. Systems for vertical expansion joints, podium levels and parapets are particularly critical.
Is waterproofing required in strata-managed buildings?
Yes, waterproofing is a core component of strata property maintenance. It protects shared infrastructure and interior lots from costly water damage. Regular inspections and upgrades help prevent disputes and unexpected levies.
What waterproofing systems are best for rooftops?
Trafficable sheet membranes and liquid-applied systems are both common. The choice depends on rooftop use, exposure, and build type. UV resistance, flexibility, and drainage integration are key considerations.
Can waterproofing help meet NCC and energy efficiency goals?
Yes, a properly sealed building envelope reduces internal moisture and improves insulation performance. This contributes to better thermal control and energy savings. Many NCC updates now consider envelope performance as part of overall compliance.
