GPR Void & Sinkhole Detection in British Columbia

Professional GPR Void & Sinkhole Detection

Void and sinkhole detection uses GPR to identify subsurface cavities that pose a collapse risk. Voids form beneath concrete slabs, pavement, and ground surfaces when underground water leaks erode the soil, when drainage fails, or when ground settles. A hidden void can cause sudden slab collapse, sinkhole formation, and catastrophic property damage. Our GPR surveys detect and map voids before they become visible, allowing property owners to address the underlying cause — often an underground water leak — before collapse occurs.

Applications

• Sinkhole risk assessment on BC properties
• Void detection beneath concrete slabs and parkades
• Underground leak investigation with void mapping
• Settlement assessment for foundations and pavement
• Pre-purchase property condition assessment

Benefits

• Detects hidden collapse risk before failure
• Maps void location and extent
• Identifies underground leaks causing voids
• Non-invasive ground and slab survey
• Protects against catastrophic slab collapse

Equipment Used

• GSSI SIR 4000 with 400 MHz antenna
• MALA ProEx with void detection
• IDS GeoRadar void mapping system
