A contractor out of Sturtevant, WI called Ground Penetrating Radar Systems to locate the rebar within the airport where they were going to be installing anchors into the slab on the second floor and did not want to hit any reinforcing or conduits. With the proper training, we were able to determine that this particular slab was a Waffle slab. The design they had laid out they were going to hit the stems in the waffle slab. With the proper training, we were able to located the stems, reinforcing and pre-tension cables in the waffle slab. While we were out there they had 6-4” holes that needed to be drilled. GPRS scanned those holes and marked out the stems, reinforcing and for these areas. With the proper training, we were able determine that one of the 4” core holes were going to be drilled into a main support beam. GPRS was able to determine the difference between a main support beam and a stem in the waffle slab. GPRS has the training and knowledge to be able to distinguish the difference between the rebar and the conduits prior to drilling. GPRS was able to mark directly on the surface with the depth and location of the reinforcing steel in real time. All of our project managers have completed the OSHA 10 training and are currently involved in an ongoing safety training course. Safety is a priority to us at Ground Penetrating Radar Systems and our thirteen year track record proves it.

Ground Penetrating Radar is a great tool to locate post tension cables, rebar, conduits. Ground Penetrating Radar is also a safe and non-destructive way to determine slab thickness and slab type. Ground Penetrating Radar Systems of Virginia scans concrete multiple times a week.
