Waterproofing for Lake Macquarie New-Builds
Waterproofing is one of the most crucial stages in any new construction. Without it, a property’s structural integrity can be compromised before it’s even lived in. Whether you're building a single dwelling, multi-unit complex or a commercial facility, waterproofing properly during construction ensures your project complies with building codes and avoids costly water damage down the line.
At Legend Waterproofing, we collaborate with builders and developers to apply precision waterproofing systems to critical areas such as basements, balconies and retaining walls. Every installation is backed by years of experience, high-grade materials and strict adherence to Australian Standards. We guarantee a dry, protected foundation that stands the test of time. We also offer renovation waterproofing and general waterproofing for existing structures.

Common New-Build Waterproofing Services
New-build waterproofing is tailored to protect key structural zones that are vulnerable during and after construction.
- Basement & Retaining Wall Protection
We use negative-side and blind-side systems to seal off underground structures from groundwater pressure and moisture seepage. - Balcony & Rooftop Waterproofing
High-traffic flat surfaces are sealed with reinforced membranes that can withstand the elements and allow for safe tiling or external finishes. - Wet Area Pre-Treatment
Kitchens, laundries and other internal wet zones are prepared before fit-out with internal membranes that prevent leaks before they start. - External Wall Sealing
We shield exposed walls and facade junctions from wind-driven rain and drainage issues with vapour-permeable barriers and joint sealants.
Frequently Asked Questions
Why is waterproofing important in new construction?
Waterproofing protects the structural integrity of a building from the outset. Moisture can compromise concrete, timber and insulation, leading to mould, corrosion and long-term damage. By waterproofing during construction, you create a barrier against water ingress before any issues arise. It also ensures your build is compliant with the National Construction Code (NCC) and relevant Australian Standards.
Can waterproofing be customised to suit different building designs?
Yes, waterproofing for new-builds is highly adaptable and should be customised to the unique design and materials of each project. Whether it’s a split-level home, a basement garage, or a high-rise balcony, we choose systems and application techniques based on location, structure, and use. This ensures durability and full coverage, even for complex or high-risk zones. Working with experienced applicators is key to achieving long-term performance.
