GPR Concrete Scanning in BC: 2026 Technology Update and Best Practices

Ground-penetrating radar (GPR) technology for concrete scanning continues to advance in 2026. New multi-frequency antenna arrays, real-time 3D imaging, and AI-assisted data interpretation are making GPR scanning faster, more accurate, and more accessible for BC construction projects. This update covers the latest technology and best practices.

Multi-frequency GPR arrays are the most significant recent advancement. These systems simultaneously collect data at multiple frequencies (typically 1.6 GHz and 400 MHz), allowing operators to image both shallow rebar (top 30 cm) and deeper utilities or voids (to 2+ metres) in a single pass. This eliminates the need for multiple scans with different antennas, saving significant time on large projects.

Real-time 3D imaging has transformed the GPR workflow. Modern systems process data and display 3D volumes in real-time as the antenna is moved across the surface. This allows operators to identify targets immediately and make informed decisions about additional scanning or marking without returning to the office for data processing.

AI-assisted interpretation is emerging as a powerful tool. Machine learning algorithms trained on thousands of GPR data sets can automatically identify rebar, post-tension cables, conduits, and voids, reducing operator fatigue and improving consistency. However, experienced operator interpretation remains essential for complex conditions.

BC safety requirements for concrete scanning: WorkSafe BC requires that all concrete cutting, coring, and drilling be preceded by a utility locate to verify that embedded services will not be struck. GPR scanning is the preferred method for this verification. Our GPR reports meet WorkSafe BC documentation requirements and provide the evidence needed for pre-construction safety planning.

LeakInspections.ca provides GPR concrete scanning services across BC. Our technicians use the latest multi-frequency GPR systems and are certified in both operation and interpretation. Call 604-239-9934 to schedule a scan for your project.
