Global GPR Services (Ontario) specializes in Ground Penetrating Radar (GPR) technology to provide reliable underground locating, (NDT) non destructive testing and subsurface imaging. The primary applications for our GPR mapping services include private utility locating (before you dig), locating post-tension cables & rebar with concrete scanning (similar to concrete x-ray) before you core or cut a concrete slab, locate underground storage tanks (UST) for environmental inspections, burial site locating & cemetery mapping to identify unmarked grave sites. We also find evidence, locate buried bodies for police forensics investigations. This technology is also used to locate sinkholes below ground or under roadways and to map drainage lines for golf courses. Last but not least is the original application for ground penetrating radar (GPR) technology in NDT geophysical surveys. Our trained GPR technicians can perform these services on site in real time. We also provide ground penetrating radar mapping services for those applications where a hard copy for future reference is required. The GPR data is interpellated to provide you with a detailed printout of the locations & depths of our findings plotted to scale.


Ground Penetrating Radar (GPR) penetrates the surface with radio waves to locate targets inside concrete. The power output is not harmful and evacuation is not required. Making this a cost effective solution compared to concrete X-Ray.
