GPRS Rises Above Obstacles to Determine a Safe Location to Core Drill for New Conduit

Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by an electrical company to locate rebar in a wall prior to core drilling for (1) 2” conduit. The area on the wall was limited due to the metal studs that were in place; we referred to using our Palm antenna rather than our 1600MHz antenna since it is suited for tightly spaced areas. We found that the wall was 14” thick and had 2 layers of rebar; we were able to easily map out a 1’x3’ area and provide the client with multiple coring options where they could drill without damaging the structural integrity of the wall.

GPR mapping is a great tool to scan areas of post tension cables, rebar, and conduits; it can also be used to locate underground utilities prior to digging or excavating. GPRS has offices throughout the entire state of California and performs GPR projects throughout the entire state, including cities like Ventura, Santa Barbara, Thousand Oaks, San Luis Obispo, Bakersfield, Lancaster and the greater Los Angeles area.

Conduits & Rebar Successfully Located in Concrete Slab Prior to Drilling Holes

Ground Penetrating Radar Systems, Inc. was contacted by a general contractor to locate conduits and rebar in a concrete slab at a waste water treatment plant. The contractor did not want to hit any rebar or electrical conduits during core drilling. All rebar and conduits were marked out in areas of concern and the general contractor was able to safely drill holes without hitting any rebar or conduits. The pictures below show electrical conduits (red paint) and rebar (black marker dashed lines) marked out on site where core drilling took place. Calling GPRS, Inc. prior to saw cutting, digging, drilling or excavating is the best way to ensure that the locations of reinforcement and conduits are identified and will not be damaged during the process.

Engineering Firm Requires Services of GPRS to Locate Utilities at Local Railyard

Ground Penetrating Radar Systems’ Indianapolis office worked with an Engineering firm in Avon, IN to locate underground utilities at a railyard. GPRS marked the location of sewer, water, product, and electric lines using GPR. Locating utilities inside the project area was crucial to project planning and execution. All utilities were marked clearly on the surface and communicated to the client.

Other services we offer are: Post-Tension Cable Location, Conduit Mapping, Rebar Mapping, Void Location and more. For any GPR and utility locating needs in Indiana call Josh Dotson at 317.504.1068 or email at indianapolis@gp-radar.com.

Permanent Record of Findings Provided on Active Medivac Helipad for Live & Abandoned Utilities

GPRS was requested on site at a hospital for a GPR survey prior to construction of a new helipad. This was an interesting project because it required working near medivac choppers that were coming in and out all day. GPRS mapped out all utilities both abandoned and live with our 400 MHz antenna then used GPS coordinates to create a CAD drawing that provided the client with a permanent record which they can refer to long after the marks are gone to insure that they could still identify the location of all utilities.

Utilities Located in the Famous Tourist District in Sedona, AZ

Ground Penetrating Radar Systems, Inc. – GPRS – of Arizona was contacted by the city of Sedona, Arizona to locate all underground utilities within the city’s main street at their famous tourist district along North State Route 89A. All utilities, such as power, communication (fiber optic and conduit), sewer lines, water, gas, and any other conduits were to be located to allow for a complete overhaul of the city’s busiest roadway.

GPRS, Inc. arrived on site and used both ground penetrating radar and radio detection / signal induction technologies to locate all utilities in the roadway. This enabled the general contractor to safely excavate the roadway while eliminating costly repairs by avoiding breakages of any underground utilities.

GPR mapping is a great tool to scan areas of post tension cables, rebar, and conduits, including PVC pipes. GPR can also be used to locate underground utilities such as water, gas, electrical, communication, sewer, and other objects prior to digging or excavating.

GPRS, Inc. has completed several similar projects in Phoenix, Tucson, Yuma, Flagstaff, Prescott, Kingman, and throughout the entire state of Arizona.

Voids and Conduits Detected Prior to Crane Placement on Factory Floor

GPRS of Central Texas was contacted to locate conduit and voids in Texas factory floor prior to moving heavy machinery. The areas where the voids and conduit were detected were marked clearly on the surface allowing the crane to be placed on solid concrete.

It’s an unfortunate and altogether avoidable tragedy when factories and other industrial facilities experience having heavy equipment (such as cranes) fall through the floor because of a sub-surface void. Employing ground penetrating radar in the hands of a trained and experienced technician can save time, money, and can keep your crew working safely.

Water Line Leak Requires Immediate Response to Locate Shut Off Valve

Water Line Leak Requires Immediate Response to Locate Shut Off ValveGround Penetrating Radar Systems, Inc. (GPRS) was contacted by a contractor to locate existing water lines and buried water valves in the parking lot of a warehouse in Tampa, FL. Justin Rasanow of GPRS used the 400MHz antenna and was able to successfully map out all of the water lines which were running through the areas of concern as well as provide intersections where other lines ran off of the main line. These intersections were believed to be where the buried valves would be located. The contractor was pleased with our results and felt relieved that they could move forward with excavating specific areas to locate the buried valves without conducting unnecessary demolition. GPRS has highly trained technicians in every major city and can often respond quickly to an emergency situation.
