GPR used to locate Post Tension and Rebar in Tucson, AZ.

Ground Penetrating Radar Systems, Inc. of Phoenix, AZ. was contacted by a general contractor to locate some PT cables and rebar at a new condo complex that is under construction. They had an issue with all of the balconies, where they were sagging a little bit and need to insert some through bolts to help support them. GPRS was quick to respond to this project to help on the contractor in a timely manner. GPRS was able to identify all obstructions in these tight areas so they could drill cleanly all the way through the slab to add these additional anchors to help support the slab. The picture below indicates our markings on the slab where we identified PT and rebar. All of this was accomplished by using a palm antenna along with the SIR 3000. By having GPRS on site for the scanning, it allowed the contractors schedule to stay on time with this project and kept them from hitting any items in the concrete slab.

Ground Penetrating Radar is ideal on a busy construction site as well as a place of occupancy. GPR does not require evacuation of the area as does traditional x-ray concrete imaging. GPR emits no radiation and is completely safe to be around. Traditional x-ray is mostly done after hours; GPR can be done during normal business hours. All data findings are marked directly on the surface at the customer’s request for the easiest interpretation of the scanning provided, with GPR there is no wait for developing films as with traditional x-ray. Only one side of the slab is needed for scanning so time and resources are much more ideal for tight schedules of projects. Ground Penetrating Radar is the new way to x-ray!
