Tracer gas and dye testing to confirm exfiltration.
When CCTV shows a suspect defect but it's unclear whether the line is exfiltrating, tracer-gas and dye-testing methods confirm leakage. We pressurize the line with non-toxic tracer gas or run dye through the system and locate the escape point on the surface. This is the methodology for confirming sewer-leak insurance claims and for satisfying engineering questions about specific defects.
Sewer Leak is a sub-division of Leak.ca, the Greater Vancouver leak detection company trusted since 1999. Every site visit is delivered by certified technicians using calibrated equipment, with documented findings formatted for insurance, engineering and procurement use.
We don't sell remediation. Our role is independent detection and assessment — the data you and your professional team work from.

Non-toxic hydrogen/nitrogen blend, the same as used for supply-line work.
Almost always — we use them together to confirm specific defects.
