Ground Penetrating Radar


Maverick Offers Concrete Imaging Services
Gound Penetrating Radar(GPR) Benefits
  • no health hazards
  • no radiation (compare to x-ray)
  • also locates materials such as PVC, not just metallic structures
  • access required to only one side of the slab (compare to x-ray)
  • quick and portable
  • on-site analysis and reporting
  • computer reporting including photos and color maps available

3D and Depth slice Surveys

The ground penetrating radar(GPR) systems used by Maverick allow us to explore a small area, with a high level of detail. The onboard computer processors are then able to calculate very accurate 3D maps of the concrete subsurface.

These maps will generally include rebar patterns, post-tension cables, conduits, voids, and the bottom of the slab. The required information tends to be more accessible, and is optimized for coring applications, where high detail, high resolution data is often required.

Left: A single depth slice can be pulled from our brand new 1.6GHz concrete imaging system. This image shows a portion of a rebar, as well as two conduits, located at a slightly shallower depth which are clearly visible, in white.

This data can be transferred to a PC for additional analysis, and a truer 3D rendering.

Right: The results of analysis on a PC, a 3D rendering can be created with very little interpretation involved. The 3D renderings, combined with the depth slices produced on-board allow Maverick Inspection to provide an easy to read final product.

Search and Find Surveys

While the grid map surveys in concrete are optimized for coring applications, or for scanning areas that are relatively small in size, the "Sidescan" surveys are optimized for larger areas. The sidescan mode relies on the technician’s interpretation of the data, but allows the machine to operate over much larger areas in a much shorter timeframe.

Such projects as saw cutting, perimeter scanning, or multiple cores in the same area are perfect candidates for our sidescan mode, enabling us to map rebar, conduit, post-tension cables, and slab depth estimates over a much larger area, where onsite reporting is all that is required. Experience counts, and Maverick Inspection is able to send technicians with hundreds of hours of field work under their belts.


In this image, we used a search and find mode because of the proximity to an obstacle. Our technician was able to obtain all of the necessary information to accurately map out the fixtures in the concrete subsurface.

This was one of over 20 areas scanned with our Ground Penetrating Radar during a single workday.

  • slab thickness estimates
  • rebar pattern identification and locations
  • detect post-tension cables
  • locate metallic and non-metallic pipes and conduits
  • detect voids and concrete heterogeneity
  • measure slab-on-grade
  • locate pipes and cables under slab-on-grade
