GPR / Concrete Scanning


Using the latest in Ground Penetrating Radar (GPR) technology to accurately locate rebar, post-tension cables, conduits any other embedded targets in concrete structures, our technicians can make sure that no damage is caused to any vital structural reinforcement. Our specialty is structural post-tensioned concrete. Our staff has been certified by the Post-Tensioning Institute, which gives us an “in-depth” knowledge of how post-tensioned cables behave inside complex structural concrete edifices.

GPR technology allows our personnel to work quickly, efficiently, and accurately in real-time. Unlike X-ray technology, our Concrete Imaging equipment can locate targets and their depths safely, without the need to vacate the jobsite. GPR is not radioactive and we can work safely around other construction trade workers on the jobsite.

Ground Penetrating Radar  Vs X-RAY

For the last few decades X-RAY technology was the predominant technique used to locate and identify targets embedded in concrete. Concrete Scanning using Ground Penetrating Radar (GPR) has overtaken X-RAY technology as the most efficient process to be used when trying to locate rebar, post-tension cables, conduits, etc. in concrete prior to concrete cutting or any other destructive procedures. However, Concrete X-RAY technology is still useful in some rare cases. Our staff has more than 15 years of ASNT Level III X-RAY NDT experience and we have managed numerous complex Concrete X-ray inspections.Concrete X-Ray Services in California

Our technicians will oversee Concrete X-ray projects from beginning to end, escorting and assisting the X-ray crew in in all stages of the inspection process. Our staff will insure that all safety measures are taken to avoid harmful radioactive exposure, as well as direct the X-ray crew to the specific locations that need to be inspected. Our technicians will collect and interpret all X-ray film produced and deliver to our customers clear inspection results in order to avoid damaging any embedded targets during concrete cutting.
