GPR Concrete Scanning at Stadium - Tampa, FL

Ground Penetrating Radar Systems (GPRS) of Tampa, FL was requested on-site by a general contractor to perform a Ground Penetrating Radar (GPR) scan at Steinbrenner Field in Tampa, FL. The purpose of our scanning was to locate all of the rebar and/or post-tension (PT) cables within the concrete which secured the stadium’s seating.

The contractor working at the stadium had plans to core drill through the concrete so that they could run electrical lines from an electrical room to a new kitchen that was to be built under the surface of the stands. However, the contractor was worried about hitting post-tension cables, and other unknown anomalies which may have been in the 10” concrete slab within having the area scanned first.

During the first part of the project, we scanned the top of portion of the concrete slabs. The results of this scan determined that there were several which areas contained post-tension cables (3” from the surface of the slab). This area also contained a foam layer, in the middle of the concrete slab. All of the anomalies within this part of the concrete slab were clearly marked onto the surface, so that the contractor could safely drill.

After scanning the top side of the slab, we also scanned from below the slab to make sure there was not any post-tension cables on the other side of the middle foam layer. We scanned multiple locations while scanning this portion of the project, and all of the locations of the anomalies were located, and marked onto the surface.

The general contractor was able to safely drill the planned 3” holes into the concrete slab after we were finished with the scan. Ground Penetrating Radar Systems is the best way to ensure the locations of rebar, post-tension cables and other anomalies in concrete prior to any type of excavation such as saw cutting, trenching or core drilling. For this project, in total, roughly (15) different 24x24” areas were scanned. Only (2) of the total locations that we scanned were within stadium seating.

The other locations scanned for this project were in the slab in which the new kitchen was going to be built upon. As this part of the scanning project was completed, all of the findings were clearly marked on the surface. We also went back through these areas, and put a clear-coat spray on our marks to make sure that our findings would not be worn away / erased from foot traffic, and other work that was going on at the location.

The photo to the right depicts Justin Rasanow, our Tampa Area Manager, scanning the portion of the stadium where stadium seating was going to be install. In this picture, Justin is using our 1600MHz antenna to scan the concrete slab. Along with the 1600MHz antenna we also used our RD-7000 (not pictured), which is a device that detects live power, and RF signals below the surface. This device is used in locating electrical or telephone lines embedded in concrete.

Following the completion of the large project, the contractor was pleased that they were able to core drill all of their locations without hitting any post-tension cables or other anomalies.
