General Contractor in Utah is Able to Avoid Extremely High Voltage Conduits by Using GPRS

Ground Penetrating Radar Systems was contacted by a general contractor to locate conduits in a duct bank. The contractor was going to hammer drill through the duct bank to replace known conduits but was worried about unknown, extremely high voltage conduits running through the concrete. GPRS was able to come on site and successfully locate two conduits that would have been hit and possibly hurt the driller if Ground Penetrating Radar Systems did not come on site to locate them.

Ground Penetrating Radar Systems used a GSSI 1600 MHz antenna for this application to locate the conduits. All findings were marked directly on the concrete at customers request for easy interpretation. GPR was ideal for this application due to the active work site in the surrounding areas. GPR emits no radiation and is safe for others to work in the area near the scan location.

For a similar scan on your job site in Utah, Idaho, or Montana please contact Adam Kubicki at 801-599-2115 or at Sonar has also been used in Toole, Provo, Ogden, Boise, Park City, Helena, and many other cities throughout the mountain states. X-ray can also be used to locate underground utilities.

Gas Lines Located Prior to Cathodic Protection Installed on UST in Kentucky

GPRS was contacted by an environmental contractor for work at a gas station in western Kentucky. Cathodic protection was to be installed on existing underground storage tanks. Prior to installing the cathodic protection, the contractor asked GPRS to locate any electric or other utilities in the nearby area.

The locating was completed using the RD 7000 to locate live power, and the 400 MHz antenna to locate other utilities. Existing electric was located around the perimeter of the UST’s and running from the gas pumps to the building. The gas lines running from the tank to the pumps were also located. By locating these utilities, the contractor was able to establish a plan of where they could safely drill. The work was completed in a safe manner.

GPRS Provides Google Earth Map Layout of Utilities Prior to Excavation in Memphis, TN

Ground Penetrating Radar Systems’ Memphis, Tennessee office worked with a local general contractor to locate utilities prior to excavation at a manufacturing facility in Memphis, Tennessee. GPRS marked location and depth of the property’s electrical service lines, site lighting, water lines, and natural gas lines. The contractor also utilized a Google Earth image mapping service provided by GPRS. The Google Earth image helped the contractor plan accordingly in the preliminary stages of construction.


GPRS uses non-destructive testing equipment to locate utilities, piping, power-lines, and underground storage tanks that are unable to be seen. Using GPRS is a safe, cost effective way to make sure you can safely drill or dig and not destroy any underground utilities or determine if USTs do or do not exist on a property.

Duct Bank Located for GC in Tampa Hospital Prior to Cutting into Concrete

Ground Penetrating Radar Systems, Inc. (GPRS) was contacted by a contractor in order to locate an electrical duct bank at a hospital in Tampa, FL. The contractor needed to make certain where this electrical duct bank was located so that they could tie into an existing conduit. The company contacted GPRS of Tampa, Florida to locate where the conduit as well as determining how deep it was; they planned to break concrete to get to the lines.

Justin Rasanow of GPRS was contacted to perform the survey at this location. Using our 400MHz antenna radar equipment and RD-7000, he was able to map out where the duct bank was located and the depth of the conduit. The contractor was pleased with our results and felt relieved that they could demo the area without damaging the existing conduit.

Soil Borings Cleared Between Cell Phone Towers in Sunland Park, TX for Environmental Company

Ground Penetrating Radar Systems Project Manager, Joseph R. Granados of El Paso Texas was contacted recently to clear soil borings between two cell phone towers in the Sunland Park area of El Paso. The environmental company completing the soil testing wanted to make sure that all drilling and boring locations could be completed as safely as possible. Utilizing GPRS minimizes the risk of striking a utility. GPRS used ground penetrating radar to locate and map out the utilities before any drilling began. Each location was scanned for utilities such as water lines, electrical lines, telecommunication, fiber lines, and gas lines. All of the telecommunication lines were mapped on site, pin flagged, and painted on the surface (with depth) to signify the location of the utility beneath the surface. Once the client was clear on the location and depth of the utilities, work could commence safely. The drilling company was able to drill each location without disrupting any live-utilities, or injuring any of their employees, thanks to the locate work completed by GPRS.
