Since 1999, our team of skilled professionals — builders, engineers, computer technicians, and contractors — has used the most advanced non-invasive technology available to find the leaks that other companies can't. We have inspected over 10,000 properties across BC and saved our clients millions of dollars in unnecessary repair costs by finding leaks before they become disasters.
Why Leak.ca for gpr clients
British Columbia's most-equipped GPR (Ground Penetrating Radar) service — for underground leak detection, pre-excavation utility locating, pre-coring concrete scanning, rebar mapping, buried tank detection, and void surveys. Multi-frequency antennas from surface-rebar (1.6 GHz) to 5+ metre subsurface (200 MHz). CAD-ready deliverables. WorkSafe BC compliant damage-prevention practice.
- Multi-frequency antennas — From 1.6 GHz (high-resolution surface scans of rebar at 5 cm) to 200 MHz (subsurface mapping past 5 metres). Right antenna for the job — not one frequency forced on every project.
- Non-destructive — zero damage — GPR sees through concrete, soil, asphalt, and most surfaces without coring, cutting, or digging. The cleanest possible diagnostic.
- Real-time + CAD-ready deliverables — We mark targets on the surface for your crew on the spot, then deliver CAD-importable maps for engineering and as-built records.
- Combined with EM locator — GPR finds what EM can't (plastic pipes, voids, rebar, tanks) — EM finds what GPR can't (live energised lines). We run both, on every utility-locate job.
- Cross-trained with acoustic + thermal — GPR is one of five technologies in our diagnostic toolkit. We deploy whichever fits the problem — or all three together for complex jobs.
- WorkSafe BC compliant — Proper damage prevention practice for excavation. Our reports support your duty-of-care obligations and reduce hit-utility liability.
- Engineering-grade documentation — Reports are accepted by structural engineers, civil engineers, environmental consultants, and BC's largest insurers. PDF + DWG/DXF deliverables.
- 25+ years across BC — Operating across British Columbia since 1999 — from single-residence slab scans to multi-hectare municipal utility maps.
Our equipment
We use AquaScan acoustic leak correlators, Gutermann hydrophones, FLIR thermal imaging cameras, GSSI ground-penetrating radar systems, and tracer gas. For long-term monitoring of large facilities and water utilities, we deploy permanent Zonescan systems with hourly data logging.
Our promise
We don't push site visits when you don't need them. The first conversation is always a free phone consult — we'll tell you whether your situation actually warrants a technician on site, or whether a DIY check is enough. That's why our 5,000+ clients keep coming back.
