GPR Used To Locate Buried Utilities

Englewood, CO

Ground Penetrating Radar Systems, Inc. of Denver, CO was contacted to locate buried utilities at the Denver Broncos Training Facility. They needed Ground Penetrating Radar and Radio Detection to locate buried utilities prior to excavating trenches for new utilities and concrete sidewalks. GPRS went out to scan and locate buried utilities using all methods available.


GPRS used a GSSI 400 MHz Antenna and RD-7000 to locate buried utilities. All findings were marked directly on the surface at the customer’s request for easy interpretation with pin flags and orange high visibility paint. GPR was needed for this job to inform the customer where they could excavate safely to place new utilities in trenches. Ground Penetrating Radar was successful for an accurate layout of all found buried utilities. Radio Detection was successful in tracing out buried utilities as well.

GPRS Locates Utilities, Tanks, and Potential Unmarked Graves

Northern Virginia

A cemetery lot requested Ground Penetrating Radar to scan the areas of concern for utilities, a tank, and possible unmarked graves.

The information on the location of these items would then be used for planning of future installations. GPRS, using Ground Penetrating Radar, identified the utilities and tank and marked on the ground areas of concern for unmarked graves.

Ground Penetrating Radar Systems of DC/Virginia has the capability and man power to finish large projects in a timely manner to ensure your project finishes on time. This was all done in a safe, timely, and non-destructive way. Ground Penetrating Radar is the new way to x-ray.

Ground Penetrating Radar Scan Performed at a Bank

Ventura, CA

image001 This image shows the scanned area; all conduits were labeled with the depth and direction they were heading.

Ground Penetrating Radar Systems, Inc. – GPRS – of California was contacted by a construction company to locate conduit and utilities in the slab prior to saw cutting. We were asked to scan 3’ on both sides of a 20’ long saw cutting path. We marked all findings on the slab with crayon, tape and marker. We also provided depths and a thorough explanation of all findings. We found that in the area we scanned, several conduits were running on angles and varied in depths of 2”-8” deep.

Due to the bank’s business hours, our client asked us to perform our GPR service in the evening/night hours as they are only allowed access during the bank’s closed hours. We used our 1600 MHz antenna and Radio Detection to locate all conduits and utilities.

Ground Penetrating Radar 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. Contact GPRS to learn how we can assist with your next project be it locating rebar, post tension cables, voids, conduits, pipes or utilities in concrete or underground.

This image shows a screenshot of the data we received; the red arrow points to a conduit we found at roughly 7” deep and the depth on the bottom right. The yellow arrows point to the rebar at roughly 2” deep. The green arrow points to the bottom of the slab which is roughly 5” thick.

Rebar Located in Wall Using Non-Hazardous Concrete X-ray

Shawnee, OK


Ground Penetrating Radar Systems – GPRS – was recently contacted by a general contractor to locate the rebar within the concrete walls prior to core-drilling for drain lines.

The work consisted of marking the reinforcing steel within the 10’x10’ area. Wade Vickers – GPRS Oklahoma – performed the concrete scanning and marked the findings directly onto the surface using orange paint.

Ground Penetrating Radar is a non-hazardous form of concrete x-ray that shows the data in real time. Due to the results being instantaneous, they may be easily communicated and understood.

Utility and Void Locating at an Existing Building

Chicago, IL

Several investors have bought an existing building and are making plans to turn it into a processing center.

The current equipment has been removed from the building and the new equipment will soon be moved in.

In order to get the new equipment into the building, large cranes are being used in several locations around the building. A local contractor has been contracted to retrofit the building for the processing center.

This contractor contacted GPRS to use Ground Penetrating Radar and Radio Detection to find any utilities or voids in the areas that the cranes are going to sit.

Technician Michael Flis was able to use the Radio Detection wand and the 400 MHz radar to find electric, water, sewer, and fire protection water lines in the area where the cranes are to be set. All lines were marked out in paint on the ground so when the cranes arrive it can be set in an area that will not cause damage to any of the utilities.

The blue markings in this photo indicate water lines that are the fire protection system. The green markings in this photo indicate storm sewer lines, and the orange markings are anomalies that could be seen with GPR but couldn’t be definitely determined what they were. The blue markings indicate water lines that are the fire protection system. Green markings are storm sewer lines.

GPR Utilized to Scan a Concrete Floor Prior to Saw Cutting inside a Hospital

Oakland, MI

Oakland, MI

Prior to saw cutting, core drilling or anchoring into a concrete structure, it’s important to have as much information as possible of what is buried beneath the surface. You can access the information needed by utilizing the proper Ground Penetrating Radar (GPR) & Radio Detection (RD) technology.

A HVAC contractor had a project inside a hospital in Oakland, Michigan where they needed to saw cut an existing concrete floor. In order to install new duct work through the existing floor, the contractor needed to know the reinforcing steel pattern in order to maintain the structural integrity of the existing elevated slab. Additionally, existing conduits needed to be located if they were present in the concrete.

Ground Penetrating Radar Systems (GPRS) of Michigan was contacted to scan the concrete floor. GPRS utilized the latest in GPR and RD technology to locate the existing reinforcing steel and any existing conduits. GPRS marked the pattern of the reinforcing steel on the concrete surface with permanent marker and/or painters tape and then communicated the markings to the onsite Superintendent. Conduits were not observed within the concrete.

GPR is an important tool to help ensure the safety of all workers involved in a project.
