Ground Penetrating Radar Systems, Inc., serving the entire state of Arizona and nationwide, was contacted by a major contractor to conduct an investigation of a residential high rise are where two water drains needed to be relocated. This required cutting through the concrete where it was critical to locate and avoid all post tension cable and rebar. Ground Penetrating Radar Systems, was required to immediately respond to the urgent nature of the job.

Post tension cable (PT cable) is typically tightened to 20,000 to 40,000 pounds per square inch when it lies beneath the concrete slab surface. It provides incredible strength and structural integrity to the slab. For that reason, it is imperative that all cables be located before any concrete cutting or concrete coring is begun. A broken and snapped cable can be quite dramatic causing great and expensive property damage, not to mention risk of injury of loss of life. GPRS was able to completely identify and locate each cable and accurately illustrate their presence in real time, completing the job within the hour. This gave the general contractor the critical information needed to move the drain while saying clear from each cable.

Ground Penetrating Radar was ideal on this site as it was a facility that had ongoing construction in progress with many people on site working. 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 near. Traditional "x-ray" is mostly done after hours whereas 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 film as with traditional x-ray. Only one side of the slab is needed for scanning, thus time and resources are efficiently save and ideal for tight project schedules or unforeseen emergencies. Ground Penetrating Radar is the new way to "x-ray"!
