Ground Penetrating Radar (GPR) has been used in mineralogical and archaeological explorations since the early 1970's. GPR now sees widespread use for non-destructive examination of man-made structures as well as for locating and mapping underground utilities and other construction obstacles. Using high frequency antennas and computer driven signal analysis, Atlantic Subsurface Imaging can not only accurately image and locate components embedded in concrete such as conduits, rebar, and cables but also detect voids or zones of construction degradation under many man-made structures such as buildings, roads, and bridges. GPR is also ideal for accurately locating buried storage tanks and utility services in soils, concrete, or asphalt.

Uses of Ground Penetrating Radar include:

  • Analysis of bridge decks in order to map deck deterioration, identify rebar location and depth, obtain overlay thickness, determine concrete cover depth, and define areas of delamination
  • Non-destructive inspection of concrete and location of rebar, tension cables, conduits, pipes, and voids embedded in walls, floors, decks, slabs, tunnels, balconies, garages, and other concrete structures. These inspections are necessary prior to core drilling and saw cutting. Go to for more information.
  • Location of natural and man-made underground obstacles such as bedrock, buried utilities (metallic and non-metallic), debris, old foundations, drums, and storage tanks
  • Identification of problem soil conditions for new construction including buried construction waste, landfills, voids, soft soil, etc.
