Lake Macquarie Waterproofing Contractors

With a diverse mix of lakefront homes, sloped sites and modern developments, Lake Macquarie demands reliable, tailored waterproofing. Excess groundwater, weather-driven erosion and exposed structures all pose a risk to foundations, balconies and retaining walls.

At Legend Waterproofing, we apply high-performance systems designed to protect new builds, renovations and existing properties across the region. Every solution is compliant with Australian Standards and adapted to your building’s needs—no shortcuts, no one-size-fits-all. From negative-side basement treatments to UV-resistant rooftop membranes, we focus on long-term moisture control backed by over 22 years of experience. Whether you're managing a commercial site or upgrading a home, our team delivers reliable results.

Basements & Retaining Walls

We install negative-side and blind-side systems to block groundwater pressure. This protects below-ground areas from leaks and structural stress.
Balconies & Rooftops

These exposed areas are sealed with UV-resistant membranes that handle movement, foot traffic and weather extremes without failing.
Planter Boxes & Courtyards

Internal zones are waterproofed before tiling to prevent leaks into subfloors and adjacent rooms. Every junction, floor and wall is sealed to code.
External Walls & Facades

Weather-exposed surfaces are sealed with breathable barriers and expansion joint treatments. This keeps wind-driven rain and moisture from penetrating the building envelope.
