GPR Leak Detection in Fort St. John, BC
Ground-penetrating radar applied to finding water where it shouldn't be: saturated zones under slabs, washouts and voids around failing pipes, buried lines located before acoustic crews listen. Radar sees the consequence; acoustics confirms the cause — Leak.ca runs both. Serving Fort St. John and the Peace Country since 1999.

Fort St. John context that shapes the work
Property stock: Energy-sector service city — industrial yards, work camps, and newer subdivisions built to northern frost specs.
Ground conditions: Clay attenuation plus metre-plus frost defines northern survey planning — summer windows give the best returns, and frost-depth services sit deeper than anywhere else in BC.
Who calls us in Fort St. John
- Slab leaks needing pipe location before repair
- Suspected washouts and voids under floors and pavement

ViewHow the Fort St. John investigation runs
- 1
Scope the question
Is the job 'find the pipe', 'bound the wet zone', 'check for voids', or all three? Antenna selection (1.6 GHz concrete to 200 MHz deep ground) follows the question and the ground.
- 2
Grid scan
Systematic passes over the suspect area — slab, pavement, or soil — capturing reflections from pipes, rebar, voids, and moisture-changed ground.
- 3
Anomaly interpretation
Radar data is read against the site's geology and construction: which anomalies are utilities, which are voids, which are saturation signatures worth acoustic follow-up.
- 4
Confirm & mark
Acoustic and moisture methods verify the leak itself where needed; everything is surface-marked and reported with depths — the map your repair crew digs or cuts from.
Why Fort St. John chooses Leak.ca
- Maps what acoustics can't hear: voids, washouts, saturation
- Locates the pipe AND the rebar before anyone cuts concrete
- Works through slabs, pavement, and soil from one side
- Paired with acoustic confirmation — radar + listening, one report
Fort St. John questions, answered
How does Fort St. John ground affect GPR leak work?
Ground is everything in radar. Fort St. John sits on predominantly Peace plateau clays with deep seasonal frost. Clay attenuation plus metre-plus frost defines northern survey planning — summer windows give the best returns, and frost-depth services sit deeper than anywhere else in BC. We pick antennas and set depth expectations to that reality — and pair radar with acoustic confirmation so the conclusion never rests on one instrument.
What do GPR leak crews actually scan for around Fort St. John?
The local mix follows the building stock: Energy-sector service city — industrial yards, work camps, and newer subdivisions built to northern frost specs. In practice that means slab-line location before repairs, washout and void checks where pavement is settling, and buried-line mapping where drawings never existed — the everyday Fort St. John radar workload.
What does gpr leak detection cost in Fort St. John?
Province-wide pricing — no regional premium for Fort St. John or anywhere in the Peace Country. Single investigations start in the low-to-mid hundreds; larger properties and multi-system files are quoted by scope. The free phone consult (604-239-9934) produces a firm number in about five minutes. Mon–Sat, 8am–6pm PT.
Can GPR actually 'see' a water leak?
It sees what leaks do to the ground. Radar reflects off contrasts — and water changes ground's dielectric behaviour dramatically. A leak shows as saturation signatures, disturbed or washed-out bedding, and voids where soil migrated into a failing pipe. GPR maps those consequences and the pipe's exact position; acoustic methods then confirm the active escape point. The pairing is the method — neither alone is the whole answer.
When is GPR the right call versus acoustic-only detection?
GPR earns its place when geometry is unknown or the ground itself is in question: no reliable drawings, suspected voids under slabs, pavement settling near a line, in-slab pipes that must be located before cutting, or rebar that must be cleared before coring into a repair. If the pipe's route is known and the question is purely 'where along it is the leak' — acoustics may be all the job needs, and we'll say so.
