Stopping Leaks at The Source

Our testing uses tracer gas, pressure decay methods, dye tests, and electronic integrity scanning. Architects, engineers, building owners, facility managers, and specialist contractors rely on our accuracy when precise leak location is needed. Our track record speaks to accuracy you can trust.

Why Accuracy Matters

Accurate leak detection prevents repeat failures by identifying actual problem locations before works begin. Testing confirms where membranes have failed, where penetrations leak, and where water enters.

Repairs based on this certainty succeed because they address confirmed problems, not assumptions. This eliminates the frustration, cost, and reputational damage of persistent leaks. If you’re in need of leak detection services, speak with our team to discuss how we can help.

Our Testing Process

Our years of experience allow us to find the best method of leak detection for your project. We use various methods including tracer gas detection, pressure testing, electronic scanning, or dye tests to find leaks and breaches quickly and accurately.

Our testing allows us to provide reports showing exactly where waterproofing has failed, supported by technical data and clear repair recommendations for effective remedial action. Speak with our team today to discuss our leak detection services.
