GPR vs X-Ray Concrete Scanning in British Columbia

Professional GPR vs X-Ray Concrete Scanning

Choosing between GPR and X-ray for concrete scanning depends on the application, site constraints, and required detail level. GPR is the preferred method for most applications: it requires access to only one side of the slab, has no radiation safety hazards, requires no permits or exclusion zones, and is faster and more cost-effective. X-ray provides extremely detailed images and is used for specialized applications where maximum detail is required and two-sided access with safety exclusion is feasible. This guide helps BC contractors, engineers, and property owners understand the trade-offs and select the right method for their project.
