Burnaby ground conditions & what they mean for GPR
Local geology: Burnaby sits on glacial till slopes with peat pockets around Burnaby Lake and Big Bend. Till slopes give clean 2–3 m penetration; peat and high water table near Burnaby Lake and Big Bend cut effective depth — survey design accounts for it.
Local building stock: Metrotown and Brentwood tower clusters on post-tensioned slabs, 1960s–70s walk-ups mid-slope, and heavy industrial along the Fraser.
Common underground water leak detection work in Burnaby
- Parkade deck scans in Metrotown towers
- Utility locates on industrial Big Bend sites
- Slab leak tracing in aging walk-ups
- Concrete scanning for Brentwood high-rise penetrations
- Buried water service lines

How the Burnaby site visit works
- 1
Confirm flow
Meter isolation confirms water is moving with all fixtures off — establishing an active underground leak before any survey cost.
- 2
GPR pipe trace
The buried line is traced and depth-profiled with 200–400 MHz GPR so the acoustic work targets the actual alignment, not a guess.
- 3
Acoustic correlation
Sensors at two access points triangulate the leak sound along the traced line — typically within 30 cm.
- 4
Mark + report
Dig window marked on the surface; written report with GPR profile, correlation output, and depth estimate delivered within 24 hours.
Burnaby questions, answered
Does GPR find the water leak itself?
GPR locates and depth-profiles the buried pipe and can image disturbed, water-saturated soil around a failure. The leak point itself is confirmed by acoustic correlation along the GPR-traced alignment — the two technologies together produce a dig window the width of a shovel, not a trench.
How deep can you trace a residential service line?
Most BC residential service lines sit 0.6–1.2 m deep — comfortably within 400 MHz GPR range in typical till and sand soils. Wet clay or saline fill reduces range; in those conditions we lean more heavily on acoustic methods and EM tracing.
Do you need to shut off my water?
Briefly, during the meter-isolation step that confirms the leak. The acoustic correlation itself works on a pressurised, flowing line — that is what makes the leak audible.
What does this cost compared to exploratory digging?
A located leak typically needs a 1 m × 1 m excavation. Un-located leaks routinely require trenching the full line at 10–30× the cost. Detection is usually $450–$1,200 and pays for itself in the first metre of digging avoided.
How deep can GPR scan in Burnaby?
Burnaby sits on glacial till slopes with peat pockets around Burnaby Lake and Big Bend. Till slopes give clean 2–3 m penetration; peat and high water table near Burnaby Lake and Big Bend cut effective depth — survey design accounts for it. We select antenna frequency to match — and where local ground limits radar depth, we pair GPR with electromagnetic locating, acoustic methods, or tracer gas so the survey objective is met regardless of soil conditions.
