GPRS Performs Radar Scans at Maryland State Emergency Center

Maryland State Emergency CenterA contractor contacted the GPRS office of Baltimore, Maryland because they were looking to trench for a new cafeteria. They needed to know that there would be no obstructions running through the slab where they would be cutting. GPRS was able to scan the entire area and map out three conduits in the area, and one was found to have live power as well. The contractor was very pleased because we were able to perform the “x-ray” within adequate time and save him the hassle of hitting any electrical and slowing down his project.

To x-ray concrete by using GPR(concrete scanning) in the Baltimore, Columbia, or Towson area, contact Michael Bell at or 410.419.3608.

Ground Penetrating Radar Scan Performed to Locate Rebar and Post Tension in San Francisco Bay Area, CA

Ground Penetrating Radar Systems, Inc. – GPRS – of Northern California was contacted by a general contractor to scan core drilling locations for plumbing and electrical at a hotel in East Bay area, CA.  The contractor was not allowed to damage rebar during core drilling and especially did not want to drill through one of the numerous post tension cables that were embedded in the slab.  GPRS was able to locate and mark the upper and lower layers of rebar onto the surface of the concrete so that the core could be performed without cutting through post tension or rebar.  Unlike conventional X-Ray, GPR is not limited to a specific size of area at each location.  We were able to scan at least a 2’x2’ area at each location so that the contractor would have safe options for drilling.

Ground Penetrating Radar is a great tool to scan areas for post tension cables, rebar, and conduits, including PVC pipes and can also be used to locate underground utilities prior to digging or excavating.  Please contact Ground Penetrating Radar Systems – GPRS to learn how we can assist with your project. To locate rebar, post tension cables, voids, conduits, pipes or utilities in concrete or underground please contact us today.  GPRS has offices throughout the entire state of California and performs GPR surveys throughout the entire state, including cities like San Francisco, Oakland, San Jose, Sacramento, Stockton, Monterrey, Fresno and Bakersfield.  Please contact Tom Solich at (925)332-6472 or to learn more about ground penetrating radar and how GPRS can assist in your projects.

Conduit and Beam Mapping at Future Jimmy Johns

Ground Penetrating Radar Systems was contacted by a contractor to locate possible utilities and beam locations in a concrete is a future location of a Jimmy Johns in Downtown Atlanta.  The contractor was asked to core 12 locations for the future installation of equipment.  To determine the best location, GPRS was contacted to map out a large area around the core sites.

Ground Penetrating Radar Systems used a GSSI 1600 MHz antenna and Radio Detection Wand for this application to locate the utilities and beams. All findings were marked directly on the concrete at customers request for easy interpretation.  GPR was ideal for this application due to the ability to mark all findings in real time.  GPR is also ideal as it 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 Georgia please contact Patrick Moulin at 770-713-7697 or at

GPR Used to Locate Anomalies in St. Petersburg, FL

In January of 2014, Ground Penetrating Radar Systems, Inc. (GPRS) was contacted by a contractor in order to locate any anomalies such as gas lines, sewer lines, electrical lines, water lines, communications lines and fiber optic lines on the campus of the VA Hospital in St. Petersburg, FL. The contractor needed to make certain of where anomalies were running in order to tie into an existing water line in certain areas. The company contacted GPRS of Tampa, Florida in order to know where the lines were located in order to avoid hitting any of them.

Justin Rasanow of GPRS was contacted in order to perform the survey at this location. Using our 400MHz antenna radar equipment, we were able to map out all of the anomalies which were running through the areas of concern as well as provide depths to the tops of the anomalies found. The contractor was pleased with our results and felt relieved that they were able to work in the areas knowing where the anomalies were located.

Below is a photo taken on-site which depicts anomalies running through an area of concern. Each line (a total of 4 separate lines in this photo) represents one anomaly. The water line they are tying into is shown in blue. The red line indicates an electrical line, while the two white lines represent an “unknown” anomaly. We scanned this area of concern using our 400MHz antenna.

Clearing Cores for Downs Electric Through the Use of Ground Penetrating Radar

 Downs Electric contacted Ground Penetrating Radar Systems of Omaha to scan concrete at the Travel Transport Building in Omaha, NE. The slab was poured over corrugated steel and so the shallow and deep parts of the pan were marked along with crossing rebar and as shown in the picture below. This made possible cuts and cores that would minimize damage to the structure and the cost to Downs Electric.

The GPRS technician used the GSSI 1600MHz antenna and RD8000 to analyze and locate anomalies in concrete on the site. GPR can also be used to locate utilities and underground storage tanks (USTs).  GPR is a safe alternative to X-ray and does not cause disruption or safety hazard to other workers or tenants. For more information about GPRS’s capabilities and availability please contact Project Manager Dane Short at 402-332-6257 or
