CONRAC, Hartsfield Jackson Atlanta
International Airport - Atlanta, GA

To reduce congestion around the Atlanta International Airport, a new system known as CONRAC is being developed for access to the rental car facilities.  As part of the construction process, the builders desired to perform random tests on some of the concrete for the overpass roadway.  Jeff Dehart of Ground Penetrating Radar Systems was able to perform the required testing on short notice.  He used Ground Penetrating Radar to locate the reinforcing steel in the concrete.  He also used GPR to locate any possible voids in or under the concrete.  Ground Penetrating Radar uses electromagnetic pulses to penetrate concrete and dirt, locating reinforcing steel, voids, and objects like utilities and USTs.  GPR operates much like ground penetrating sonar.

Jeff Dehart runs GPRS operations in the Atlanta, Georgia area.  He can be reached at (404)593-9227 or by e-mail at jeff.dehart@gprsinc.com.  Concrete scanning for the purposes of identifying the location of rebar and post-tensioning is the most frequent service performed by the GPR technicians at GPRS.
