Underground Leak Detection · Every BC city

The leak is down there somewhere. “Somewhere” is what we eliminate.

Water disappearing underground — service lines, irrigation mains, site services, buried supply loops — located to dig accuracy without exploratory trenching. Acoustic correlation, GPR, thermal, and aerial screening, sequenced by the crews that have found BC's buried leaks since 1999. The alternative — trenching along the line until water appears — costs more than the whole investigation, every time it's tried.

Why locate before digging

From meter movement to one clean dig

  1. 1

    Confirm & isolate

    Meter behaviour with the building valve open versus closed proves the leak is underground and brackets which line owns it — ten minutes that aims everything after.

  2. 2

    Trace the line

    Electromagnetic locating and GPR establish where the pipe actually runs and how deep — because correlating a leak on a line whose route is imaginary produces imaginary results.

  3. 3

    Listen & correlate

    Acoustic sensors bracket the run; correlation math and ground-microphone verification converge on the escape point. Soil and pipe material set expectations honestly — and the technique adapts to both.

  4. 4

    Mark for one dig

    Paint, depth, and the evidence in a short report. Your excavator or plumber opens one hole, at the right spot, sized to the repair instead of the search.

Underground leaks, answered

How can you find a leak under a metre of soil without digging?

Three physical signatures reach the surface: sound (pressurised escape resonates along pipe and soil — correlators and ground mics triangulate it), ground change (GPR maps saturation and washed-out bedding), and heat behaviour (saturated soil lags dry soil's daily swing — readable thermally, including from the air on long runs). Stacked, they converge on a dig point; any one alone can be fooled.

Why doesn't underground leak water just show up on the surface?

Because soil routes it away first — along trench bedding, into drains and gravel seams, downward through free-draining ground. In much of BC, a service line can pass thousands of litres a day for months with the lawn above bone-dry. The meter notices; the surface lies. That asymmetry is the entire case for instrument-based location.

What does 'dig accuracy' actually mean for my repair cost?

The difference between an excavation sized to a repair and one sized to a search. A located leak is typically one bucket-width hole at the mark — hours, minimal restoration. An unlocated leak is trenching along the line until water appears, then restoring everything the trench crossed: lawn, irrigation, driveway, sometimes the same week's landscaping twice.

Our line runs under the driveway. Does that change the approach?

It strengthens the case for locating before cutting — pavement makes exploratory digging genuinely expensive, and it also carries leak sound usefully for acoustic work. GPR scans through the slab or asphalt to confirm routing and any void development; the cut, when it happens, is one rectangle at the mark instead of a sawn trench on a hunch.

What's the difference between this hub and your municipal water main services?

Scale and client. This hub serves property-side underground leaks — homes, acreages, strata sites, and commercial parcels, from the meter inward. Network-side work for utilities — distribution surveys, noise loggers, DMA analysis, break location on public mains — lives at our municipal water main hub. Same physics, same crews, different programs.

Do you locate other utilities before the repair dig?

On request and on congested sites, yes — the same visit can include electromagnetic locating and GPR over the dig box, so the excavation that fixes the water line doesn't find the gas service the hard way. See our utility locating hub for the full discipline.
