Identify subsurface voids before they collapse pavement or slabs. Delivered across Richmond by GPR Leak Detection, a Leak.ca division.
604-239-9934Same-day response in RichmondVoids and sinkholes don't announce themselves until they fail. Pre-collapse, they're detectable by GPR as anomalous returns in soil density. We deliver void surveys for parking lots, slab-on-grade buildings, civic infrastructure and post-storm assessments. The work produces a referenced map of suspect locations and a recommendation for follow-up — typically targeted coring or geotechnical investigation. For municipal and government clients, this is often a preventive program rather than a reactive one.
Pre-excavation locates over peat substrate, concrete scanning for City Centre tower projects, void detection along older dyke fills.
Richmond's built environment — low-rise wood-frame condos, single-family on small lots, City Centre high-rises, agricultural in east Richmond — shapes how void & sinkhole detection is delivered locally. Richmond sits at 1 m above sea level on the Fraser delta. The high water table makes slab leaks and basement seepage common, and the dyke-protected drainage system means stormwater issues quickly become structural ones. Construction is largely 1980s–2000s with growing concrete-tower density in City Centre.
