ABOUT WATERPROOFING INTEGRITY
Australia’s Leading Independent
Waterproofing Advisors
We do not install waterproofing. We advise, inspect, test and remediate, independently. From design through to defect resolution.
Why Waterproofing Integrity Exists
Waterproofing Integrity was established in 2019 in Sydney because the construction industry needed something it did not have: truly independent waterproofing advice.
Too often, the people advising on waterproofing are the same people installing it. That creates a conflict of interest that costs developers, builders and asset owners millions every year in preventable defects.
We set out to change that. By operating exclusively as advisors, with no ties to installers, contractors or product manufacturers, we give our clients something rare: advice they can trust completely.
Today, we support projects across multi-residential, commercial, infrastructure and health sectors, working with some of Australia’s most respected builders and developers.
What Makes Us Different
Three principles that define everything we do.
Independence
We do not install waterproofing. We never have, and we never will. That means every recommendation we make is free from commercial bias. You get honest, evidence-based advice with no hidden agenda.
Authority
With 10,000+ inspections, 750+ designs and active involvement in Australian Standards committees, our team brings depth that most consultancies simply cannot match. We know the standards because we help write them.
Confidence
When we sign off, you can build, certify and hand over with confidence. Our independent verification gives builders, developers and asset owners the assurance they need to move forward without worry.
Who We Help

We take waterproofing off your risk register.
