This GPR scan took place on an elevated concrete slab at the new Toyota Headquarters in Plano, TX. The customer needed to install 150 brackets for reinforcement of the glazing of the building. The concrete slab was reinforced with post tensioned (PT) cables which can cause serious injury or damage if struck during drilling. The PT cables needed to be clearly marked before the customer could drill holes for the anchors.
David Hagenmayer with Ground Penetrating Radar Systems, Inc., was contracted to scan the area requested and mark out all PT cables and obstructions in the concrete. David was able to determine the precise locations of the existing lines. The client was then able to safely and effectively drill.

Ground Penetrating Radar Systems was recently contacted to locate and map all utilities at Carolina Hospital System’s Florence, SC campus prior to directional boring.
The equipment used in the scan was a 400MHz antenna capable of identifying objects at a depths of up to 6’-7’, a SIR-3000 processing system and RD7000.
While on site, GPRS technician James Ross, scanned 4 locations totaling approximately 2 acres to identify any anomalies that would indicate electrical conduits, water mains, gas lines, and any other pertinent utilities moving through the anticipated path. After further investigation at the suspected site we were able to determine that there were utilities running through the proposed path. Not only could we identify these obstructions, but we also provided accurate depths to each utility.

Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by a directional drilling company to locate utilities in a parking area prior to running a new cable line. The scope of work consisted of a 100 LF path that crossed several main utilities that provide service to the local apartment complex nearby. We scanned 15’ on either side of the center of the path and marked all the findings on the surface with chalk paint as requested. Among the findings were water, gas, electric and sewer.
GPR mapping is a great tool to scan for post tension cables, rebar, and conduits; it can also be used to locate underground utilities prior to digging or excavating. GPRS has offices throughout the entire state of California and performs projects in cities like; Ventura, Santa Barbara, Thousand Oaks, San Luis Obispo, Bakersfield, Lancaster and the greater Los Angeles area.

Ground Penetrating Radar Systems, Inc. – GPRS – of Arizona was contacted by a large mining company to locate all underground electrical utilities in a large renovation / upgrade project outside of Camp Verde, Arizona. There were known electrical lines present and it was essential that their locations were properly documented to prevent injury, damage, and costly repairs or interruptions to mine operations.
This project was a particular challenge to the contractor who needed to find a private utility locator who could respond promptly to their remote and rural location. GPRS was able to respond within 24 hours from the client’s first contact. GPRS specializes in quick response in rural or metro areas throughout the state of Arizona.
GPRS, Inc. arrived on site and used both ground penetrating radar and radio detection / signal induction technologies to locate the utilities on site, marking them all in real time with paint and producing immediate results. GPRS’ quick response and clear markings communicated each utility’s location and prevented any damage to the underground utilities – preventing risk as well as any detrimental impact to critical mining and safety operations. This enabled the general contractor to continue to safely excavate with confidence, while eliminating costly repairs and safety issues.
GPRS has done many projects such as this in Phoenix, Tucson, Yuma, Flagstaff, Prescott, Kingman, and throughout the entire state of Arizona and performs GPR surveys throughout the United States. Contact Nate Holscher (Regional Manager) at 480.227.8614 or

a large industrial site in Chesterfield, VA, because the existing as-built plans were inaccurate. GPRS Project Manager Josiah Donaldson verified the location, depth, and direction of several utilities on site that allowed the engineers to design and build around them. In addition, a CAD file was generated along with an aerial image overlay to give the customer accurate existing records of utilities.
GPRS of Virginia provides concrete scanning as well as utility locating to identify underground storage tanks, utilities, and subsurface anomalies. For projects in Richmond, Williamsburg, or Virginia Beach, VA contact Josiah Donaldson at email@example.com or call 804-393-8744 or 757-319-1903.
Ground Penetrating Radar Systems (GPRS) was requested on site by a general contractor to perform a Ground Penetrating Radar (GPR) scan at The Rock and Roll Hall of Fame. The purpose was to locate all rebar and columns to clear locations for core drilling through the concrete floor. All findings were marked out in the areas of concern and the general contractor was able to safely core drill and avoid all rebar and columns. Ground Penetrating Radar Systems is the best way to ensure the locations of reinforcement and conduits prior to saw cutting/drilling through concrete. The pictures below show rebar and columns taped out on the surface.

Recently a local airport hired a utility company to install communication lines to feed their new terminal being constructed. The utility company has a long history of using Ground Penetrating Radar Systems for locating utilities in preparation for directional boring and trenching. The utility company had several miles of trenches to be cleared and GPRS was up to the task.
GPRS used a 400MHz antenna and RD7000 (Radio Detection) to map out the precise locations of all communication, water, sewer, gas and electrical lines. Ground penetrating radar is an effective and efficient tool for accomplishing these goals and GPRS had the area mapped on the surface of the ground in less than two weeks. After explaining the findings to the on-site contact, a full report was provided to the client for their records. This ensured that the client would have the findings on record for future projects. The clients were more than pleased with the results and the trenches were dug without incident.
