Concrete Scanning to Locate Post Tension Cables on Rooftop

Ground Penetrating Radar Systems (GPRS) was requested on site by a general contractor to perform a Ground Penetrating Radar (GPR) scan. The purpose of this scanning project was to locate all of the post tension cables within a concrete slab. Multiple areas were scanned on the roof to ensure that the contractor would not hit any post tension cables during the anchor drilling process. All of the cables that were located in areas of concern were marked with their depth and location. Ground Penetrating Radar Systems is the best way to determine the exact locations of reinforcement and conduits prior to cutting/ drilling through concrete. If the contractor would not have had called GPRS: The Experts In GPR, they would have hit multiple cables in area shown below. Thanks to GPRS, LLC., all of the anchors were drilled and placed without any cables being hit.
