Identify subsurface voids before they collapse pavement or slabs. Delivered across Vancouver by GPR Leak Detection, a Leak.ca division.
604-239-9934Same-day response in VancouverVoids 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.
Locating private utilities before excavation in dense rights-of-way, concrete scanning for towers and parkades, void detection in older fill areas.
Vancouver's built environment — high-rise concrete towers, wood-frame walk-ups, character single-family homes and pre-war duplexes — shapes how void & sinkhole detection is delivered locally. Vancouver mixes 1910s heritage homes with 60-storey concrete towers, so leak investigations vary enormously between properties. Heritage neighbourhoods like Kitsilano and Strathcona tend to show old copper and galvanized failures; downtown and Yaletown towers more often have slab penetrations and envelope failures behind window-wall systems.
