Find Out First: What’s Under Your Concrete?

Know what you are getting into before you dig into your concrete. Sterling Concrete Sawing & Drilling Ltd. can provide you with comprehensive concrete inspection services, including non-destructive testing with ground-penetrating radar scanning and X-ray services using our own equipment and trained crews. Our technicians are the most experienced and the best equipped in the field of structural inspection.

Ground Penetrating Radar (GPR)

Ground-penetrating radar (GPR) can be utilized to image both concrete slabs and walls. High frequency radar signals are directed into the concrete. When reflected back to the device, the signals create a clear image in real time. From the image, we can also determine the thickness of the concrete and the exact spacing of concrete. The signals can penetrate up to 24 inches from one side. This can be combined to examine up to 48 inch thicknesses when access is given from both sides.

Our GPR helps you locate the positions of rebar, post-tensioned cables, conduit, and other near-surface objects to identify the safe places to drill.

GPR can accurately locate metallic and non-metallic reinforcement and pipes in and below concrete slabs. GPR can also detect flaws in concrete structures. We can scan for the absence of grout in concrete block walls and missing rebar. We can verify slab thickness and determine the depth of material cover on reinforcement.


We manage the entire X-ray process from beginning to end. We will be onsite when our Radiography crew arrives. We will analyze the results, provide you with reports and we can take the next step to complete whatever work needs to be done. Scan before you dig or cut. Know what you are getting into to save time and expenses from unexpected damages.

Radio Detection Flux Scanning

Sterling uses Radio Detection Flux Scanning for detection of live electrical conduits before we cut. This is a safety measure to prevent any harm to our operators and damage prevention to the client.

Remember to always check before you dig or cut—contact us in Mississauga, Barrie or Cambridge to learn more.
