Ground Penetrating Radar Systems of Salt Lake City, UT was contacted by US Signs of Denton, Texas to assist on a sign install on a concrete roof in Midvale City, Utah. The sign was to be anchored to the roof on a building in the Union Park Center and there was concern the anchor bolts would damage the Post-Tension Cables in the concrete. There was only access to one side of the concrete and in the floor below was an active office so traditional concrete x-ray in Utah could not be used. GPR technology was up to the challenge as it only needs access to one side of a concrete surface and does not emit any harmful x-ray radiation.
GPRS of Utah mobilized to the site and performed the non-destructive GPR concrete scan. The on-site technician was able to identify the post-tensioning tendons within the concrete. The PT-Cable locations were marked on the surface so that when drilling the anchor bolts no steel was hit in the process. There were multiple areas of banded cable that were discovered and those areas were marked out with instructions stating “DO NOT CORE”.
GPRS Regional Director Jason Schaff can be contacted at 801.599.2115 or Jason.Schaff@GP-Radar.com. Ground Penetrating Radar Systems is able to locate rebar, post-tension, conduits, gas lines and much more within concrete structures. GPR is safe, reliable and less expensive than concrete x-ray.
