Ground Penetrating Radar (GPR) is the latest technology for locating embedded objects

Ground Penetrating Radar (GPR) is the latest technology for locating embedded objects in concrete which include but are not limited to rebar, conduits (both plastic and metal) and post tension cables.

Aug. 8, 2012 - PRLog -- EXARO Technologies Corporation specializes in GPR services along with all facets of underground utility locating in the bay area and Southern California which is an asset because when it comes to locating objects imbedded in concrete one single tool cannot do the job as well a multiple tools can.

EXARO was formed and incorporated in the State of California on March 2005.  With headquarters in Northern California in Bay Area Burlingame and a Southern office in Santa Ana the EXARO team has worked throughout the State of California.  EXARO is sought after because of its reputation on delivering excellence with a sense of urgency at competitive pricing; basically the best value for the money.

EXARO is the only union company specializing in Ground Penetrating Radar in the Bay Area and the State of California.  Hence, the daily cost of operations is higher then non-union contractors so in order to stay competitive EXARO focuses on delivering quality and productivity.  When it comes to GPR services an hourly or daily rate has no significance without the productivity and quality components.  A miss-marked service conduit or post tension cable can be catastrophic and costly to a project.  Having to re-drill due to miss-marked rebar has an impact on project productivity.  While the ground penetrating radar technology has its limitations and accuracy tolerances the experience and skills of the operator are critical for quality results and productivity; this is where EXARO Technologies Corporation fits the challenge. So what other technologies does EXARO use to locate embedded objects in concrete?

There is another technology available to locate embedded objects in conduit, x-ray.  X-ray continues to fall behind as gpr continues to take a larger market share.  There are several reasons for this.  First is the x-ray is far more expensive then gpr scanning.  X-ray also requires access to both sides of the subject to be investigated so that the x-ray can be taken.  Then there is a lag in time for obtaining the results; the x-rays have to be developed whereas with GPR the results real time; available immediately.  Also, some agencies don't want the use of x-ray on their properties because of the associated radiation.  This is not an issue with GPR because the technology here is transmission of electromagnetic waves from the antenna on the GPR unit to the surface under investigation.

The demand for investigation of embedded objects in concrete continues to grow significantly in California partly due to the fact that it is an earthquake prone State.  Therefore, preservation of the integrity of existing concrete re-enforcement is critical.  In addition over the past 20 years there have been and continue to be a large number of seismic strengthening projects for buildings and other infrastructure.  Many of these projects strengthening design require drilling and doweling into the existing concrete; hence locating the embedded objects is important.
