The partial area of a large office building was going to be renovated which required removal of the existing concrete slab-on-grade. To perform slab removal process safely, the facility manager wanted to know if there were buried utility pipes or other objects under the slab.

Concrete Science, Inc. conducted a radar survey to detect buried objects, if any. The survey was carried out on the slab at 5-ft. intervals by moving the antenna in a straight line and monitoring the response on a monitor. The survey revealed that there were grade beams under the slab every 20-ft. No other significant objects were detected.
