Waterproofing isn’t guesswork, it’s science. At Wattaproofing Excellence, every membrane we install is verified using PosiTector 200 thickness testing to ensure it meets Australian Standards and performs exactly as designed. If you can’t measure quality, you can’t guarantee it — that’s why we do.
What Is Waterproofing Thickness Testing?
The PosiTector 200 is an ultrasonic gauge that measures the precise thickness of cured waterproofing membranes without damaging the surface. It gives instant, digital readings in microns, confirming that each coat reaches the required minimum for durability and warranty compliance.Unlike visual checks, this method leaves no room for error. It verifies coverage across large areas, ensuring your waterproofing system is uniform, strong, and truly watertight.
Why It Matters for Builders and Strata Managers
In large or high-value projects, small inconsistencies can create big problems later, leaks, warranty voids, and insurance disputes. Thickness testing removes that risk.
Compliance: Confirms every membrane meets AS 3740 and AS 4654.2 standards.
Accountability: Generates digital reports with time-stamped readings for certification.
Reliability: Guarantees long-term performance and a full manufacturer-backed warranty.
When you engage Wattaproofing Excellence, you receive data to match our workmanship, measurable proof that your waterproofing is built to spec.
Our Testing Process
After each membrane layer cures, we test multiple points across the surface using the PosiTector 200. Results are recorded, saved, and compared against manufacturer specifications. If any area falls short, we re-apply and retest before sign-off. Only once all readings pass do we proceed to tiling or finishing.This ensures consistent quality across every balcony, basement, and bathroom we waterproof, from Sydney homes to multi-storey developments.
Quality, Verified and Backed
Every completed project comes with a 7-year workmanship warranty, supported by thickness-testing documentation. It’s how we guarantee watertight performance, not just by sight, but by science. When you choose Wattaproofing Excellence, you’re not just getting waterproofing, you’re getting proof of waterproofing.
