Ground Penetrating Radar Systems, LLC.
A Testimony to Calling Before

GPRS was called out to investigate a concrete slab for possible conduits AFTER almost all power had been cut to garage doors, alarm systems, and security gate keypads. This particular concrete slab was an elevated slab with an underground parking garage beneath it. The contractor was only resurfacing the concrete for a courtyard patio and assumed that all the conduits to the garage doors and other security systems were surface mounted in the garage below.

But boy, they wrong this time.... Almost all of the conduits were actually within the slab and branching off in all sorts of different directions. To avoid costly and time-consuming fixes call GPRS BEFORE any and all excavation.

Before Scanning

“Time is a primary currency traded on any given construction project. At Ground Penetrating Radar Systems, our everyday efficiency in operations allows us to respond to the immediate needs of our customers, often within 24 hours or less.” (

Scan before you plan! This ensures worker safety and saves valuable time by targeting specific areas of concern. GPRS can also provide GPS reports overlaid on Google Earth or overlay information on pre-existing CAD files for future building plans. This is all done in a safe, time efficient, non-destructive manner.

After Scanning

GPRS assists by giving a real-time depth view of subsurface hazards such as reinforcing, utilities, conduit, underground storage tanks, voids, etc. This reduces the likelihood of subsurface obstruction strikes during core drilling, saw cutting, trenching, soil boring, directional drilling, anchoring, and other sub-surface applications.

Ground Penetrating Radar Systems uses the GSSI (Geophysical Survey Systems, Inc.) Sir-4000 technology in locating. GPRS also uses the RD-8100 Locator to locate live power and radio frequency (RF) signals underground. We can also detect utilities in or under concrete via induction or conduction with an exposed or known surface utility line.
