GPRS Jacksonville Locates Voids at Port and Utilities along Riverwalk

Ground Penetrating Radar Systems’ Jacksonville Florida office was recently contacted to locate utilities near downtown Jacksonville.  The client was working on a property near the Riverwalk area and was installing new communication lines.  They wanted to avoid damaging any utilities running to the number of restaurants and condo buildings along the south side of the St. Johns River so GPRS was contracted to complete private utility locates. The proposed trench and directional bore path was scanned using GPR and radio detection devices. All utilities were painted and flagged directly on the ground surfaces.  Following the investigation all of the findings were collected using a GPS Trimble device to collect the locations of each of the items. Water, gas, electrical, conduit, communication, fiber optics, natural gas and other unknown utilities were all found in the area. Each location was collected and placed into an aerial map and later inserted into a CAD file.

The client was able to use the markings in the field and the mapping services following the investigation to safely and timely install the new utilities and avoid damaging any live utilities already in operation.  If you would like a similar locate completed or a quote for your project requiring GPR, please visit the “contact us” page at  In the image below you can see GPRS technician Adam Yunker scanning with his 400 MHz antenna along the Riverwalk area in downtown Jacksonville.
