Sigma GPR Services Inc. offers  concrete imaging services across the British Columbia. Using the latest in Ground Penetrating Radar (GPR) technology to accurately locate rebar, post-tension cables, conduits any other embedded targets in concrete structures, allowing non-destructive testing to take place prior to any drilling, sawing or coring.

With our innovative portable and fast GPR (ground penetrating radar) concrete scanner, we can detect and measure the depth of cover, diameter and positioning of reinforcing bars (rebar) over a wide area. The concrete cover and rebar diameter estimation element is best performed with pulsed magnetic induction technology – and we always use the best tools for the job.
