Void & Sinkhole Detection in British Columbia
Water that escapes underground washes out soil, leaving voids beneath slabs, roads and foundations — the precursor to settlement, slab failure and sinkholes. GPR detects these voids before the surface gives way.
Leaks.ca is the educational leak detection hub and service-support division of Leak.ca, helping BC property owners understand leak risks and connect with professional detection services when needed.
Void and sinkhole detection uses GPR to image loss of support beneath slabs and ground — voids, washouts and soft zones — often where a leak or drainage failure has eroded the soil. It informs repair and confirms whether settlement has an underground cause.
- GPR survey of the slab or ground area
- Identify voids and low-density zones in the profile
- Correlate with any nearby leak or drainage issue
- Map the extent for remediation
- Voids and washouts beneath slabs
- Soft and disturbed soil zones
- Loss of support under foundations and roads
Investigating settlement, slab cracking or suspected washout from a leak.
Geotechnical and restoration contractors map voids to scope grouting and repair, and to confirm whether a leak caused the loss of support.

Void & Sinkhole Detection — FAQ
Yes. Water escaping from a buried line or failed drainage washes away soil, leaving a void that grows until the slab or ground above loses support and settles or collapses. GPR finds these voids early, and locating the leak stops the cause.
