Controlled Flood Testing (ASTM D5957): Definitive Waterproofing Verification
Prove That Your Waterproofing Works — Before It’s Covered Up
Our Controlled Flood Testing service confirms watertightness through a simple, proven process: we isolate an area, fill it with water under controlled conditions, and observe for leaks over a specified period. The process follows ASTM D5957, the recognised international standard for flood testing of horizontal waterproofing systems.

Why Independence Is Everything
No product affiliations
We don’t sell membranes, coatings, or systems. Our advice is based on what’s right for your project, not what earns us a commission.
No contractor relationships
We don’t install and we don’t subcontract to installers. When we inspect or test, there is no commercial pressure to approve.
No conflicts of interest
When our report says a membrane has failed, it’s because the data says so. Our NATA accreditation means our testing has legal standing.
