Gross & Welch Attorneys at Law called Ground Penetrating Radar Systems, Inc. when they needed to verify the placement of rebar on three residential properties. There was concern by the owner of the properties that the rebar was not placed according to plans due to extreme cracking in the concrete surface. GPRS of Albuquerque mobilized to the site and scanned 17 different locations at three different properties. GPR operator Jason Schaff used Ground Penetrating Radar technology to scan the surface revealing a wire mesh below the surface and also the rebar and its spacing.

In the image below you can see the wire mesh with consistent 6 inch spacing and then the 3 rebar that are closer to the surface. The plans called for rebar to be placed every 32 inches: this scan shows that the spacing was actually 40 inches between each bar. When using GPR technology the results are immediate. There is no need to waste time developing film or setting up equipment like concrete x-ray. GPR allows the data to be marked on the surface in minutes or in this case save digital photos for later use. Rebar Mapping/Post-Tension Cable mapping in concrete is the most common application for GPRS.
