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 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.
Here are answers to frequently asked questions about our services. If you have other questions, please don't hesitate to get in touch.
See all FAQsWe test all waterproofing system types including below-ground tanking, cavity drain membranes, podium deck waterproofing, flat roof membranes, balcony and terrace waterproofing and basement structural waterproofing.
Yes. As well as identifying where leaks exist, our reports recommend appropriate repair approaches. We specify which methods are suitable for identified failures, whether localised repairs will suffice or more extensive works are necessary, and what materials and techniques align with your waterproofing type.
Costs depend on building size, waterproofing system type, testing methods required, and site accessibility. We provide transparent quotations once we understand your specific requirements. It’s worth noting that testing typically represents a small fraction of potential repair costs and prevents far greater expenditure on misdirected works—the return on investment is substantial.
Most testing methods work with minimal disruption to building occupants. Tracer gas detection, pressure testing, and electronic scanning are relatively unobtrusive. For commercial properties, residential buildings, or facilities that can't close, we plan testing to respect occupant needs while delivering accurate leak location services.
Absolutely. We're independent consultants with no contractor affiliations or product manufacturer ties. We regularly test waterproofing installed by others—whether for quality assurance, leak investigation, or dispute resolution. Our assessment is impartial and objective, focused solely on system integrity and performance.
