When a contractor needed to verify the location and depth of the reinforcing steel prior to core drilling, they called GPRS, Inc. to locate the rebar. GPRS marked them directly onto the surface. GPRS used ground penetrating radar for the concrete scanning to precisely locate the reinforcing steel. Since the results are immediate GPRS was able to complete the concrete scanning accurately and quickly.
