Working in concrete poses hidden dangers. Whether it’s new construction or a renovation project, there is usually a need to cut or core a concrete slab. Encountering rebar, electrical conduit, post-tension cables, or other structural elements can be costly. It will wreak havoc on your schedule and create a safety hazard for your employees. Control Point Associates, Inc. can locate these hidden risks with our state-of-the-art Ground Penetrating Radar (GPR) technology.

news-concrete-scanning-ladder-radarGround Penetrating Radar is a non-invasive, non-destructive way to produce a cross-sectional view of objects embedded within concrete, as well as detecting voids and measuring slab thickness. Our technicians scan concrete structures in real-time, providing immediate results right in the field. The GPR signal is harmless, requiring no special permits or exclusion zones, unlike traditional x-ray methods.

Our GPR technology allows us to:
  • Locate rebar, pre-tension, and post-tension cables
  • Identify utility cables and conduits
  • Measure concrete slab thickness
  • Detect voids within or hidden below surfaces
  • Locate safe areas to core drill
  • Locate safe areas to sawcut slab or wall openings
  • Preserve the structural integrity of the concrete


High-resolution concrete scanning is the most reliable, non-destructive way to locate hazards within structures before cutting or coring. Control Point Associates, Inc. is able to scan many types of concrete structures, including suspended slabs, slabs-on-grade, columns, beams, and tilt walls. Contact us today to find out more, and gain peace of mind on your next project.
