Slab Leak Detection in Ladner, 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 Ladner and the Metro Vancouver region with certified technicians, non-invasive methods, and insurance-ready documentation — since 1999.

Ladner ground conditions & what they mean for GPR
Local geology: Ladner sits on delta silts and organic soils at sea level. High water table keeps effective GPR depth shallow; fortunately Ladner services run shallow too. Drainage mapping relies on dense gridding plus EM.
Local building stock: Historic fishing-village core with century-old service alignments, dyke-side properties, and working agricultural edges.

How the Ladner 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.
Ladner 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 Ladner?
Ladner sits on delta silts and organic soils at sea level. High water table keeps effective GPR depth shallow; fortunately Ladner services run shallow too. Drainage mapping relies on dense gridding plus EM. 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 Ladner, or dispatch from elsewhere?
Ladner is part of our standing Metro Vancouver 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).
