Locating Rebar and Conduits

Cutting and coring experts and other construction professionals often need a reliable way to non-destructively locate targets within concrete structures prior to drilling, cutting or coring.  GPR is the most versatile tool available for these professionals due to accuracy, ease-of-use and safety.  

With GSSI’s high-resolution antennas, even small targets are located in real-time and can
be seen to depths of 18 inches or more.  Only single sided access is required to perform
GPR surveys, and thousands of square feet can be inspected in one day.  This method is
also extremely safe and does not require evacuating areas as with radiography (X-ray), which shuts down other trades working within the vicinity.  X-ray can not find non-metallic utilities buried within concrete like GPR technology can, and measuring depth of targets with X-ray can be difficult.

Concrete NDT Applications for GPR

Concrete Professionals Use GPR For:

  • Concrete inspection – locating metallic and non-metallic targets in walls, ceilings
    and floors (rebar, tension cables, conduits, PVC pipes, and more)
  • Structure inspection – bridges, towers, tunnels, balconies, garages, decks,
    columns, slabs, monuments
  • Condition assessment – map concrete condition for rehab planning
  • Measure slab thickness
  • Void location
