What happens when an elevator gets shut down on a 9-story building renovation? Put up a temporary elevator on the outside…Buck Hoist. But before the buck hoist can be installed, it must be anchored. Before it gets anchored, the concrete needs to be scanned to keep the structure and the buck hoist secure.
GPRS was called on to scan for the buck hoist anchors during a renovation of a dorm building at UNC Charlotte. The areas for the anchors were successfully scanned, and the anchors for the buck hoist were installed without touching any rebar.
To complete this job safely, the general contractor drilled holes in the corner of each room, so that any worker in the room could use a temporary concrete wedge anchor connected to a self-retracting lifeline (yo-yo). This made transitioning from room to room quick, efficient, and safe.
The equipment used to scan was the 2GHz Palm GPR antenna. This antenna provides high-resolution images at depths up to 12-15 inches, depending on concrete conditions. The smaller profile allows scanning in tighter spaces than normal GPR concrete antennas. The 4000 SIR unit was used to receive the radar signal and display the signal on its screen. This equipment along with the experience of GPRS project managers lead to accurate and helpful findings.
Upon completion of the job, a job summary report is sent giving information on the work that was done: site specific information, findings, equipment used, and advice for safely proceeding with the job.

The beauty of scanning is that you don’t hit anything! It’s not all that often we have the chance to see the finished product installment after our work is done, but it sure is nice to see that everything was installed safe and smoothly.
For this particular project, Ground Penetrating Radar Systems (GPRS) was contacted by a general contractor for some night-time scans at an Ulta Beauty store. This store was unlike most because it was built on a suspended slab over a retention pond. Needless to say this required some clearing prior to coring.

Scan before you plan! This ensures worker safety and saves valuable time by targeting specific areas of concern. GPRS can also provide GPS reports overlaid on Google Earth or overlay information on pre-existing CAD files for future building plans. This is all done in a safe, time-efficient, non-destructive manner.

GPRS assists by giving a real-time depth view of subsurface hazards such as reinforcing, utilities, conduit, underground storage tanks, voids, etc. This reduces the likelihood of subsurface obstruction strikes during core drilling, saw cutting, trenching, soil boring, directional drilling, anchoring, and other sub-surface applications.
Ground Penetrating Radar Systems uses the GSSI (Geophysical Survey Systems, Inc.) Sir-4000 technology in locating. GPRS also uses the RD-8100 Locator to locate live power and radio frequency (RF) signals underground. We can also detect utilities in or under concrete via induction or conduction with an exposed or known surface utility line.

Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by a solar company in order to scan for reinforcing or conduits prior to anchoring. The proposed anchors were to be imbedded 4” deep and are meant to hold down an electrical transformer and other electrical equipment. We scanned an approximate 10’x5’ area on a 12” thick slab that consisted of 2 layers of 12” on center rebar at depths of 2” and 8” deep. Among the other findings were 8 conduits at approximately 5”-6” deep; we marked these findings on the slab with red paint.
GPR scanning is a great tool to use for post tension cables, rebar, and conduits; it can also be used to scan for 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. Please contact Alfredo Espinal at 805-729-5877 or email@example.com to learn more about ground penetrating radar and how GPRS can assist in your projects.

Ground Penetrating Radar Systems was contacted by a general contractor to locate the reinforcement inside the concrete foundation of an office building. The GC was getting pressured from the structural engineer to find out exactly how the reinforcement laid so they would cut as little as possible and therefore keeping as much of the structural integrity of the foundation as possible. The general contractor was attempting to drill two 18” holes through the foundation to push through piping for a new communications system inside the building. GPRS was able to come on site within 24hrs of the requested job and safely locate all of the reinforcement inside the concrete foundation despite the tight quarters inside the crawl space making it the shortest and smoothest path possible for the contractor to take.
Ground Penetrating Radar Systems used a GSSI 1600 MHz antenna for this application to locate the reinforcement. All findings were marked directly on the concrete at the customer’s 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. There are no pictures taken but a continuous scan making it faster to read a larger area throughout a slab while also allowing for hourly work instead of a per hole job.
For a similar scan on your job site please contact Adam Kubicki at 682-999-0046 or at email@example.com. GPR has been used to locate utilities in Dallas, Fort Worth, Plano, Addison, and Carrolton, Texas. GPR can also be used to locate your residential gas line, water line, sewer line, and other important utilities that can cause safety issues as well as financial. Ground Penetrating Radar Systems has been in business since 2001 and are the leading experts in GPR. With over 200+ technicians in the field around the nation, creating an environment each technician has access to that can provide a different outlook to every job creating a more accurate and safe reading of the data that is site specific.
Ground Penetrating Radar Systems, Inc. – GPRS – of Arizona was contacted by a local contractor to locate private utilities on a commercial site. The contractor was unable to complete the project without locating a high voltage 480 volt power line as well as an unknown sanitary / sewer / septic line.
Ground Penetrating Radar Systems, Inc. arrived on site and used both ground penetrating radar and radio detection / signal induction technologies to locate all utilities on site. This enabled the general contractor to continue to safely excavate with confidence, while eliminating costly repairs by avoiding utility line strikes and breakages.
Ground Penetrating Radar services are a great tool to scan areas for identifying underground utilities that are public or private. GPRS also scans for objects below concrete surfaces such as post tension cables, rebar, and conduits, including PVC pipes. Ground penetrating radar can also be used to locate all kinds of underground utilities such as water, gas, electrical, communication, sewer, and other objects prior to digging or excavating. GPRS can use ground penetrating radar technologies as well as signal induction techniques in order keep you fully informed about what objects lie below the surface. Safety is a primary concern. Don’t dig, excavate, or cut concrete without knowing what lies below the surface.
GPRS can respond in very quick time to accommodate the timeframe of your project and keep you from production delays while keeping you safe. Please contact Ground Penetrating Radar Systems – GPRS to learn how we can assist with your next project.
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.

Ground Penetrating Radar Systems, Inc. – GPRS – of Northern New Jersey was contacted by a general contractor to locate all pipes and live conduits within and under a slab on grade in order to install a new sanitary line within an educational hospital. The general contractor was planning on saw cutting the slab and digging down 3 feet in order to install a new sanitary line. To ensure safe cutting and digging the client requested all pipes and conduits within 3’ to be located. The entire trenching area was scanned and any obstruction was located and marked out in real time. Multiple live conduits were located both embedded in the slab and under the slab within the trenching area. The contractor was able to cut shortly after the scanning completed and the collaborative efforts and real time results helped keep the job on schedule.
