Penhall Technologies can help you locate rebar, pipes, post and pre tension cables, conduits and many other subsurface hazards that may be hidden in concrete. Our expertly trained analysts can also detect voids within or underneath concrete slabs. As a safety leader in the industry, contractors, engineers, and government agencies have come to trust Penhall first for safe and precise scanning services.
Ground penetrating radar used to scan for embedded objects in concrete
Penhall was asked to use ground penetrating radar to examine an area for embedded objects at a site in Reno, NV. The scanning was administered to ensure that it was safe to perform an electrical saw cutting. The cutting was for a concrete trench that measured 6′ x 3″ x 2″.
Rooftop scanning on elevated slab to locate post tension cables and existing conduit
For a client in Reno, NV, Penhall completed some GPR scanning, where we inspected several locations for obstructions, such as rebar, post tension, conduit, or utilities. All 12 locations were located on an elevated concrete slab that was 6” thick. After scanning, it was safe do perform core drilling.
Identify hazards within concrete before cutting and resurfacing
Over 60% of a slab was inspected using ground penetrating radar to locate conduits and post-tension cables for a client in Reno, NV. The identification of these hazards was necessary prior to the concrete cutting and resurfacing of the parking structure.
Concrete scanning used to identify patterns of tension cables and rebar
For this project, Penhall completed a concrete scanning job in Sparks, NV. We used ground penetrating radar to scan an area that measured 2.5′ x2.5′. The client wanted us to identify the existing post tension cables and rebar in the concrete.
