Canadian Subsurface Investigations - QR Code


Canadian Subsurface Investigations (CSI) Inc. provides Ground Penetrating Radar (GPR) services throughout the province of British Columbia, Canada. GPR is recognized as one of the most powerful sensing instruments available today. It is a safe, non-evasive technology for concrete scanning and underground utility detection.

The high frequency GPR is a powerful prospecting tool that can be used to map rebar, post tension cables, metallic and plastic conduits embedded in the concrete. Furthermore, it can also be used to measure concrete thickness, rebar cover, and locate voids in or underneath the concrete structure. GPR is superior to radiography (X-Ray) in speed, efficiency, and cost-effectiveness. Unlike radiography, GPR is capable of continuous data collection, requires only one-sided access, and provides real-time inspection results. In addition, GPR poses no radiation hazards; it is safe to operate in public places, such as: Airports, Hospitals, Police Stations, and during construction, and does not require any evacuation of personnel.

Canadian Subsurface Investigations (CSi) also performs private utility locate using both mid-frequency Ground Penetrating Radar (GPR) and Electromagnetic (EM) locator to map a variety of subsurface utilities, including: Gas, Electric, Water, Storm/Sewer, Fiber-Optics, and Oil Tanks.

The results from our Technical Services can also help you to reduce the high cost of insurance by providing the necessary information at your site. Often, contractors will core, trench or excavate without the proper information, which can be dangerous by not knowing what lies in the subsurface. This may result in cutting into high voltage power cables, fiber optics, gas lines and more, all of which are costly to repair. As well, you would not want to have “bad” press covering your site or your company.
