Ground Penetrating Radar Scan performed at Parking Garage, Los Angeles, CA

Ground Penetrating Radar Systems, Inc. – GPRS – of Southern California was contacted by an engineering firm in order to scan for post tension cables on the third level of the parking structure. The purpose of the work was to repair post tension cables throughout all the levels of the structure due to many of the cables snapping or no longer sustained the proper amount of tension.  The client needed areas marked out prior to chipping through the 6” thick slab. We scanned (7) 10’x4’ areas on level E and marked all findings on the surface with spray paint. We marked all post tension cables with red paint, rebar was marked with blue paint and beams were marked with pink paint.

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