Ground-Penetrating-Radar-Scan-Performed-in-Ventura-Southern-California.jpg

Ground Penetrating Radar Systems, LLC. - GPRS of California was contacted by a construction company to locate all utilities within their boring bath at an elementary school in Ventura, CA. They were to directional bore from an existing communication vault into the school property to provide time warner cable services. We used two methods to find utilities, first we used radio detection and found power lines and we also hooked on to tracer wires to find the gas that feeds into the school. We also used Ground Penetrating Radar to find the water lines and sewer lines. We were also able to provide depths for all findings and used spray paint to mark the ground where utilities were embedded.

Underground_Utility_Locate.jpg

Ground Penetrating Radar technology was recently used in Evansville, WY (Casper, Wyoming area) to assist the Envirocon Company in located underground utilities prior to excavation. The site was a former Chevron refinery and there was concern over what utilities may lay below the grade.

One call locates were called to the site prior to GPRS’ arrival to mark out utilities. The ground penetrating radar survey on this site was able to verify the location and depth of the prior locates. The Project Manager of Ground Penetrating Radar Systems Denver was also able to locate a pipe that was not marked out by any prior private utility locating company.

Locating utilities in Casper by using GPR is a great way to increase the chance that all impediments are discovered prior to any digging or excavation taking place. A radar scan can assist in locating pipes, conduits, gas lines, water lines, sewer pipes, trenches, duct banks, high voltage conduits and much more.

GPRS-of-Wisconsin-Locates-Private-Utilities.jpg

Ground Penetrating Radar Systems, LLC. – GPRS of Wisconsin was contacted by large contracting company to locate the fiber optic, electrical, and any other sub surface utilities or anomalies. This site was in Green Bay, Wisconsin. Where the utilities were to be located were around a large cell tower. There were many ground wires running in these areas, but our ground penetrating radar and radio detection equipment was able to locate the lines in search. GPRS, LLC. was informed there was only one fiber optic line running through the area, but GPRS, LLC. located two fiber optic lines. GPRS, LLC. also identified the electric line running through the area. This allowed for the excavators to dig safely and keep costs down. The locating of these utilities is a nominal fee in comparison to the thousands of dollars it would cost to repair all of the utility lines.

GPRS-Scans-Concrete-Wall-in-St-Louis-Missouri.jpg

A local contractor tried to bore a path into a building in order to run a new water line. Upon entry into the building, the bore head lost its wireless link with the bore beacon, and its point of entry could not be determined. GPRS scanned the entire wall and found the point where the bore head had penetrated a few inches. This verification set the job back on schedule and ensured against any potential facility damage.

GPRS_Scans_Concrete_To_Locate_Electrical_Conduit_Before_Core_Drilling_In_Central_Florida.jpg

Ground Penetrating Radar is a new technology that is extremely helpful to mark out reinforcing steel, conduit, post-tension cables, pre-stressed cables and other pertinent obstructions that lie within a concrete slab. GPR is applicable on elevated slab, slab on grade, and as you’ll see in this entry, cement walls. Ground Penetrating Radar Systems, LLC. is of the top GPR companies in its industry and has grown to provide GPR services nationwide.

GPRS Project Managers were recently contacted in Central Florida for concrete scanning at a large facility being constructed. Throughout the construction of the building there have been many changeovers. The scope of this job was to scan multiple walls on the ground floor to locate electrical conduit within the concrete wall before new holes were core drilled. It was essential that the conduit be located and not destroyed in the core drilling process. A GPR scan was performed to locate reinforcing steel and conduit prior to core drilling through the 12” thick wall.

Gas_Line_Location.jpg

Miami Dade College needed to update their records for utilities on site. The area that needed to be scanned, using ground penetrating radar, was their Kendall campus. Thus they contacted specialists in concrete scanning, GPRS. This is an ideal application for ground penetrating radar as utility detection and CAD file drawings are GPR specialties. GPRS, LLC. from Miami, FL took the call and mobilized to the site.

On site, GPRS was able to detect water lines and gas lines, as well as other utilities. They marked them on the ground with colored spray paint and flagged them with depth estimates. GPRS then collaborated with Rene, with Kaufman Lynn to update the CAD files. Glenn Zebrowski of GPRS updated the schools files. The project was a success and why radar is “The New Way to X-Ray”.

A contractor needed to drill penetrations through an elevated slab with post-tension cables and embedded electrical conduits to install electrical lines. The area that needed to be scanned, using ground penetrating radar, was located in a condominium master bedroom on the 3rd floor. Thus they contacted specialists in concrete scanning, GPRS. This is an ideal application for ground penetrating radar as conduits and post-tension cable locating are GPR specialties. GPRS, LLC. in South Florida took the call and mobilized to the site.

On site, GPRS was able to identify all the obstructions quickly and accurately. Ron Anderson clearly marked all post-tension cables and conduits directly on the slab. GPRS then collaborated with the contractor, as to the best places to drill to avoid striking a conduit or a post-tension cable. The project was a success and why radar is “The New Way to X-Ray”.

Ground Penetrating Radar Systems was recently called to locate piles beneath a concrete slab on grade at NASA in Hampton, Virginia. Scope of work was to scan a 30’ x 30’ area in the basement of a building to locate and map out underground piles so the engineers on site could core drill and test the composition and structure of the existing piles. They were not sure if the piles were concrete or possibly made of a wood material. There were several piles that were said to be in the area according to old drawings from the building. We also were asked to map out the rebar in the slab so they could get a clean core sample when they went to drill by the piles. Ground Penetrating Radar is an effective and efficient way of locating material in a concrete slab and underground. It also allows us to provide a depth to how deep the material is.

Ground Penetrating Radar is an excellent option to locate radiant heat tubes in a concrete slab. A homeowner in Norwell, MA had a situation where they needed to place anchor bolts in a concrete slab to secure a car lift inside the garage. The homeowner contacted Ground Penetrating Radar Systems of Massachusetts to mark out the path of the radiant heat tubes. GPRS mobilized to the site the same day to perform the GPR investigation. GPRS marked their findings directly on the garage floor surface so it was clear where the radiant heat tubes were running. They also marked the depth of how deep the radiant heat tubes were in the concrete slab. The homeowner was able to insert the anchor bolts without compromising the radiant heat & costing him a lot more money to break up the floor.

Concrete_Slab_Scanning_At_Construction_Site_In_Miami_Florida.jpg

A general contractor needed to core drill holes in the concrete to install new plumbing lines in a new construction site in Miami. The area that needed to be scanned, using ground penetrating radar, was a new construction project and was known to have critical structural steel in the concrete. Thus they contacted the specialists in rebar locating, Ron Anderson of GPRS. This application, rebar locating, is a common job for GPR. GPRS, LLC. in South Florida took the call and mobilized to the site.

On site, GPRS was able to identify the structural rebar, quickly and accurately. They marked them on the surface of the ground and provided a report explaining the results. GPRS then collaborated with the general contractor, as to the depth and location of the structural rebar. The advantage to radar compared to X-Ray is that radar can locate the structural rebar from the surface of the ground, without dangerous radiation. The project was a success and why radar is “The New Way to X-Ray”.
