Locating Conduits Prior to Saw Cutting of Concrete Slab - Charlotte, NC

Ground Penetrating Radar Systems (GPRS) was requested on to perform a Ground Penetrating Radar (GPR) scan. The purpose of this scan was help identify the location of any existing conduits in the slab prior to saw cutting the concrete slab with a saw. The customer stated that they knew existing conduits may have been in the area because they had already saw cut some of the concrete before having it scanned and hit a price of conduit that resulted in loss of power in the complex. They figured it may be a good idea to have the concrete scanned just in case more conduits were present. As you can see, once I arrived onsite I was able to scan the concrete in the area where they had planned on cutting the rest of the concrete and revealed multiple conduits that were right in the path of the saw cutting they were planning to do.

We used a GSSI (Geophysical Survey Systems, LLC.) Ground Penetrating Radar Unit with one specific antenna. The antenna used on this project was a 1600 MHz antenna along with Radio Detection. This antenna is useful in many different applications. This specific application was slab on grade with around a 4” concrete slab. For this application we also used Radio Detection. This device detects live power and RF signals underground, allowing us to locate electrical or telephone lines even if they are below the minimum size requirements to be detected by GPR. It also allows us to detect utilities via induction or conduction with an exposed or known surface of the conductive utility.

With the use of this equipment and the experience of GPR, we were able to help the customer avoid any conflict before saw cutting anymore of the concrete slab. As you can see, we were to help the customer identify areas with potential hazards and save them from any more potential danger of cutting through any conduits that may have live power on them. There are many applications where ground penetrating radar may be applicable. GPRS also specializes in private utility locating. Many private companies and business will not be able to use a free locating service to help identify their utilities. These same customers may prefer a more skilled company that has GPR capabilities to help identify utilities for better accuracy and thoroughness as well, this is when they would rely on GPRS to perform these services.

If you feel you may have a project that you could use our services on or may be able to benefit from GPR, you can reach out to me directly with my contact information below. More information about our services that we offer can be found on our website as well:
