Slab Leak Detection in Salmon Arm, BC
GPR maps the in-slab plumbing and rebar so thermal and acoustic findings convert into a single small repair patch — not a jackhammered floor. Serving Salmon Arm and the Shuswap region with certified technicians, non-invasive methods, and insurance-ready documentation — since 1999.

Salmon Arm ground conditions & what they mean for GPR
Local geology: Salmon Arm sits on lakeshore silts with till benches above. Bench till scans conventionally; lakeshore silts run wetter. Agricultural parcels around the bay carry extensive private piping.
Local building stock: Lakeside town centre, farm parcels, and hillside view subdivisions.

How the Salmon Arm site visit works
- 1
Thermal pass
Infrared imaging maps the moisture or heat plume through the slab surface — the first non-invasive evidence of where the leak is.
- 2
GPR slab map
1.6 GHz GPR images every pipe, rebar bar, and PT cable in the suspect zone so we know exactly what is beneath the thermal anomaly.
- 3
Acoustic confirm
A ground microphone over the mapped pipe confirms the pressurised leak sound at the suspected point.
- 4
Patch window mark
Repair window marked between rebar/PT cables — your plumber cuts one tile-sized patch, clear of structure.
Salmon Arm questions, answered
Why does the GPR step matter if thermal already found the warm spot?
The warm spot tells you roughly where the water is — not where the pipe is, or what else is embedded in the slab. Cutting on thermal alone risks hitting rebar or a post-tension cable. GPR maps the slab internals so the patch lands on the pipe and nothing else.
Can you scan post-tensioned slabs?
Yes — PT cable mapping is one of GPR's core jobs. Cutting a tensioned cable is catastrophic, so on any post-1970s suspended slab we map cables first and mark the repair window between them.
Does slab thickness affect detection?
Standard 100–200 mm residential and commercial slabs are well within 1.6 GHz range. Thickened footings and toppings up to ~45 cm still image clearly; beyond that we adjust antenna frequency.
Will my floor finish be damaged?
No. GPR, thermal, and acoustic are all surface-contact, non-destructive methods. The only opening ever made is the final repair patch — by your contractor, exactly where we mark.
How deep can GPR scan in Salmon Arm?
Salmon Arm sits on lakeshore silts with till benches above. Bench till scans conventionally; lakeshore silts run wetter. Agricultural parcels around the bay carry extensive private piping. 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.
Do you actually work in Salmon Arm, or dispatch from elsewhere?
Salmon Arm is part of our standing Shuswap service area — the same certified technicians and equipment that cover the rest of the region. Scheduling is typically within 24–72 hours, with same-day response often possible during business hours (Mon–Sat, 8am–6pm Pacific).
