Water Ingress & Leak Repairs
Identify, repair, and prevent water ingress issues in building façades, roofs, balconies, basements, and wet areas using precision diagnostics and tailored waterproofing solutions.

Water ingress is one of the most destructive and expensive building defects, capable of compromising structural integrity, damaging interiors, and leading to mould growth that can impact occupant health. Unlike visible damage such as cracking or spalling, leaks often travel along concealed paths, making the source difficult to locate without specialist investigation.

At Atomic Projects, we approach water ingress rectification with the precision of a forensic investigation. Our process begins with advanced diagnostic tools such as electronic leak detection (ELD), infrared thermal imaging, moisture mapping, and flood testing. This allows us to pinpoint the exact entry points — whether it’s a failed membrane, compromised joint, poorly installed flashing, or porous façade material.

Once the cause is identified, we design a rectification strategy tailored to the building element and its use. This may include:

  • Membrane Repairs or Replacement: Reinstating waterproof integrity with high-performance sheet or liquid-applied systems.
  • Sealant & Joint Remediation: Removing failed sealants, preparing joint substrates, and installing UV- and movement-resistant sealant systems.
  • Flashing & Termination Upgrades: Fabricating and installing custom flashings that exceed minimum code requirements.
  • Substrate Remediation: Treating or replacing damaged concrete, masonry, or timber to prevent future deterioration.

We don’t just “patch leaks” — we eliminate the root cause and provide preventative measures to protect against recurrence. Our repairs are tested before handover, with photographic and test result documentation included in our completion reports.

The result is a watertight building envelope, extended asset lifespan, and confidence that your property is protected against Sydney’s increasingly severe weather patterns.
