GPRS Locates Utilities in Charlotte, NC

GPRS Locates Both Private and Public Utilities in Charlotte, North Carolina

GPRS, Inc. was requested on site to perform a ground penetrating radar (GPR) scan on a commercial property in Charlotte, NC. The purpose of this scan was to help identify the location of any utilities or anomalies on site prior to excavation. The customer had requested a public locate for utilities, however based on the location of their project, a private utility locate was needed to help identify any possible utilities in the area. GPRS was able to identify the location of the existing utilities and mark any other anomalies that may have been in the way prior to excavating. All the utilities that were located with GPR were able to be identified with approximate depths. GPRS was able to save the customer valuable time and help prevent any possible damage to unknown utilities.

For this specific project, we used a GSSI ground penetrating radar unit with one specific antenna. Ground penetrating radar can be used to identify buried or hidden components within a structure or beneath a surface. This non-destructive method uses antennas of varying strengths to transmit a signal into a surface. As the signal encounters different components within that surface, it is bounced back to a receiver at the surface to locate utilities and other buried items. Average GPR penetration in the Carolina market is about 4-6’ depending on GPR antenna. GPRS also used radio detection on this project as a supplement to the GPR. Radio detection detects live power and RF signals underground, allowing us to locate electrical or communication lines. Radio detection also allows us to detect utilities via induction or conduction with an exposed or known surface of the conductive utility. With multiple tools available to use, each specific scenario is addressed accordingly to ensure we maximize our findings onsite. With the use of this equipment and the experience of GPR, GPRS was able to help the customer avoid any conflict before excavating, digging or completing a directional bore for the new utilities being installed. GPRS was able to help the customer identify areas with potential hazards at the most affordable cost.

There are many applications where ground penetrating radar may be applicable. For instance, GPRS also specializes in concrete scanning. When scanning concrete, GPR can be used to help identify reinforcement in a slab, approximate concrete thickness or verifying any potential hazards in the slab prior to core drilling or saw cutting.
