After performing the scan, the proposed path for the fiber line have several utilities in the way (electric, communications, sanitary, water and gas)

(A large void was directly in the middle where the customer wanted to bring in the fiber to the building)

Recently, Ground Penetrating Radar Systems (GPRS) was requested to perform a Ground Penetrating Radar (GPR) survey. A nation wireless carrier is planning on performing a directional boring to an existing cellular tower. After performing the scan, the proposed path for the fiber line have several utilities in the way (electric, communications, sanitary, water and gas) The secondary path for the fiber lines also had some obstructions. A large void was directly in the middle where the customer wanted to bring in the fiber to the building. After talking to the property owner, it was verified what was located was an old coal shaft.

As a supplement to GPR, we also used radio detection to help identify live power, communication and other utilities that may have a power signal on them. Once the utilities in the path were identified they were marked directly on the surface so the customer will know where the utilities are. After all the utilities were located on this project, the customer brought in a trencher to install drain tiles. Because GPRS was onsite to help identify any anomalies that may be present, the customer was able to drill on the site without striking and existing utilities that may be present.

We used a GSSI (Geophysical Survey Systems, Inc.) Ground Penetrating Radar Unit with one specific antenna. For portions of this project involving concrete scanning, a 1600 MHz antenna was used with the GPR. This antenna allows data collection to a maximum depth of approximately eighteen inches, depending on the condition of the concrete slab.

With the use of this equipment and the experience of GPR, we were able to help the customer understand the slabs thickness. There are many applications where ground penetrating radar may be applicable. GPRS also specializes in concrete scanning for post tension cables, scanning for conduits in a concrete slab prior to core drilling or just helping identify the structural properties that may be present in an existing concrete wall or slab.

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.
