Underground Leak Detection in British Columbia

Underground leaks present a unique challenge because the leaking pipe is completely invisible, buried beneath soil, pavement, or landscaping. In British Columbia, properties with buried water service lines, private water mains, and extensive irrigation systems are at risk of losing thousands of litres of water daily through a single underground leak. The surface indicators may be subtle — a patch of unusually green grass, a soft spot in the lawn, or simply a water bill that has doubled without explanation. By the time water bubbles to the surface or a sinkhole appears, significant water loss and potential property damage have already occurred.

LeakInspections.ca employs a multi-technology approach to underground leak detection that combines acoustic correlation, ground-penetrating radar, tracer gas testing, and advanced listening equipment. Our technicians walk systematic grid patterns over the suspected pipe route using ground microphones that amplify the sound of water escaping from pressurised pipes. We refine the location using leak noise correlation, where two sensors calculate the exact leak position based on sound arrival time differential. For challenging cases involving plastic pipes, deep burial, or low-pressure systems, we deploy tracer gas testing where a hydrogen-nitrogen mixture is injected into the pipe and detected at the surface. Ground-penetrating radar maps the pipe location and identifies soil saturation patterns. This multi-layered approach ensures even the most elusive underground leaks are precisely located.

We serve residential, commercial, municipal, and industrial properties across all of British Columbia, with technicians available for both scheduled surveys and emergency response. Our detailed reports include GPS coordinates, acoustic recordings, and GPR imagery that satisfy insurance requirements, municipal leak adjustment programs, and contractor dig instructions. By pinpointing the exact leak location before any excavation begins, we eliminate wasteful exploratory digging and reduce repair costs by up to 70%.
