Ground Penetrating Radar (GPR) is a geophysical locating method that uses radio waves to capture images below the surface of the ground in an innovative way. It is a non-intrusive method of surveying the sub-surface to investigate underground utilities such as concrete, asphalt, metals, pipes, cables, or masonry. This nondestructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum and detects the reflected signals from subsurface structures.

GPR can have applications in a variety of applications, including rock, soil, ice, fresh water, pavements, and structures. In the right conditions, technicians can use GPR to detect subsurface objects.

Significant applications include:

GPR can be used to detect the following wide range of materials:

  • Gas Lines
  • PVC (non-metallic)
  • Plastic Lines
  • Electric Lines
  • Conduit
  • Rebar/Metal
  • Communication Lines
  • Storm Lines
  • Sewer Lines
  • Voids or Air Pockets
  • Groundwater
  • Bedrock
