Tracer gas and dye testing to confirm exfiltration. Delivered across Richmond by Sewer Scans, a Leak.ca division.
604-239-9934Same-day response in RichmondWhen 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.
Lateral failures in 80s/90s subdivisions, infiltration during king tides and heavy rain, root intrusion in mature-tree streets.
Richmond's built environment — low-rise wood-frame condos, single-family on small lots, City Centre high-rises, agricultural in east Richmond — shapes how sewer leak detection is delivered locally. Richmond sits at 1 m above sea level on the Fraser delta. The high water table makes slab leaks and basement seepage common, and the dyke-protected drainage system means stormwater issues quickly become structural ones. Construction is largely 1980s–2000s with growing concrete-tower density in City Centre.
