Waterproofing for Heritage Structures
Design and installation of discreet, high-performance waterproofing systems for heritage-listed and historically significant buildings — protecting against water ingress while preserving architectural authenticity.

Heritage buildings are often more vulnerable to water ingress due to ageing materials, outdated construction methods, and decades of weather exposure. While protection is essential, inappropriate waterproofing can damage historic fabric, trap moisture, or visually alter the façade. The challenge is creating a system that delivers modern performance while maintaining complete respect for the building’s history and heritage requirements.

At Atomic Projects, we combine conservation principles with advanced waterproofing technology, ensuring long-term protection without compromising heritage value. Our work complies with Heritage Council guidelines, Burra Charter principles, and relevant Australian Standards.

Our Heritage Waterproofing Process

  1. Heritage Assessment & Approvals
    • Collaborate with heritage consultants and architects to document existing conditions.
    • Secure necessary permits and approvals from heritage authorities.
  2. Material Compatibility Testing
    • Assess original materials — stone, brick, render, lead, timber — for porosity, salt content, and compatibility with proposed treatments.
  3. Moisture & Leak Investigation
    • Use non-invasive methods such as moisture meters, infrared scanning, and drone inspection to identify ingress points.
  4. System Selection
    • Prioritise breathable membranes, vapour-permeable coatings, and discreet detailing to maintain material performance.
    • Avoid coatings that seal moisture in or change the building’s appearance.
  5. Installation
    • Apply systems by hand, low-pressure spray, or brush depending on substrate sensitivity.
    • Integrate flashing upgrades, discreet drainage solutions, and joint remediation where needed.
  6. Final QA & Documentation
    • Provide photographic records, maintenance recommendations, and warranty documentation.
    • Ensure all interventions are fully reversible wherever possible.

Common Heritage Waterproofing Applications

  • Parapet and cornice sealing.
  • Below-ground tanking and negative waterproofing for heritage basements.
  • Lead flashings and copper cappings restoration.
  • Clear, breathable façade water repellents.
  • Waterproofing for decorative stonework and masonry features.
