Underground Utilities Located in Warsaw, VA

The Richmond office of GPRS was recently subcontracted by Warsaw County Public Works to locate an underground water main so that could be used to provide water for a new site development project in the coming months. The scope of work was to locate the underground water main in an open field and provide a depth. After locating the line using GPR, it was confirmed by the county using the excavator and a test probe.

Ground Penetrating Radar Scan Performed in Metler, Southern CA

Ground Penetrating Radar Systems, Inc. – GPRS – of California was contacted by a telecommunications company to locate underground utilities in a large agricultural field just south of Bakersfield, CA. There is a large area where workers have machinery and a large telecommunication pole was to be placed there. The proposed drill was to be 30 feet deep with a diameter of 6 feet. GPR was used to scan the area to locate utilities. We also use Radio Detection for finding live power and communications signals and connecting to metal pipes and tracer wires. GPRS was able to locate 2 water and electrical lines. The pipes were painted on the surface and were provided with a depth.

Geophysical mapping is a great tool to scan areas of post tension cables, rebar, and conduits, including PVC pipes and can also be used to locate underground utilities prior to digging or excavating.

GPRS Locates Utilities in Fueling Terminal – Jacksonville, FL

Ground Penetrating Radar Systems was contracted recently to complete a utility locate within a fueling terminal prior to installing a new pipe rack. Even though the project was simple, creating a pipe rack for approximately 100 linear feet to support a storm drain pipe, the project could easily have been complicated if a utility was struck during the digging process. The foundations for the pipe rack were to be augured out and concrete poured in. It was necessary to locate the electrical conduit, water lines, control lines and other underground utilities prior to drilling for the foundations, as a disruption of these services could cause a major shut down for the terminal. Following the investigation the contractor was able to install all foundations safely, with minimal risk in regards to endangering his employees or the facility in which they worked.

In the image below you can see GPRS technician Adam Yunker scanning with the 400 MHz antenna to locate underground utilities near an existing pipe bridge.

Locating Underground Storage Tank at the Residential Home in Decatur, GA

Recently, GPRS was contacted to locate an underground storage tank (UST) and any other possible utilities within the backyard of a residential property. Plans for this property needed the location of the abandoned oil tank to be determined for any future work to proceed on the property.

With the 400 MHz antenna, GPRS technicians were able to scan a predetermined area and provide clear locations for soil borings. Using the 400 MHz antenna, the length, width and depth of the UST was able to be marked on the ground using spray paint. The 400 MHz antenna will typically reach depths from 8-12’. An SIR-3000 computer system is what displays the data for interpretation. Although this project did not require documentation showing the results of the survey, GPRS is capable of providing a written report to accompany the on-site markings.

In the pictures below you can see the UST clearly marked. With the mobility of the push cart we were able to scan the area in a quick and thorough fashion. The second photo is a probable septic tank that was not known to be on site and was added to be cored and sampled for the environmental studies.

If you would like a quote for a scan to possibly find a UST, please visit the “contact us” page at to contact your local GPRS representative.


Void Detection in Chicago, IL

GPRS was contacted by Roehrborn Development of Winnetka, IL to detect possible voids under an apartment building in Chicago, IL. The customer was renovating a kitchen in one of the apartments on the lower level and noticed the floor sinking towards the exterior wall. By using GPR, the technician on site, Brian Cox, was able to locate where the voids were. This enabled the customer to know where it would be effective to pump the slurry into the ground and prevent further sinking of the floor.
