Ground Penetrating Radar Systems, Inc. – GPRS – of Wisconsin was contacted by a law firm to investigate the rebar in 20 columns of a barn in Madison, WI. The barn had partially collapsed due to misplacement of rebar within the columns on one side of the barn. The columns that collapsed exposed the rebar and the rebar placement did not meet the specifications for the structure. The columns that collapsed were then repaired to meet the standards required. The client requested that GPRS, Inc. scan the rest of the columns and mark the rebar to confirm the rebar was placed correctly to ensure no more repairs would be required and that the workers and the cattle were safe.
In addition, GPRS was able to use our sister company, True Point Laser Scanning (TPLS) to scan all the columns and the rest of the structure to fully evaluate the building. GPRS has access to 2 GHz Palm antennas which are much smaller than a typical GPR antenna and allow us to scan in much tighter spaces or in areas with limited scanning surfaces. The Palm antenna was perfect for scanning these columns due to their shape and smaller size.
Ground penetrating radar is a great tool to scan areas of post tension cables, rebar, and conduits, including PVC pipes and can also be used to locate underground utilities prior to digging or excavating.
