Ground Penetrating Radar 

Ground Penetrating Radar (GPR) is one of the most efficient geophysical techniques, able to cover large areas in a relatively small amount of time.

Our highly experienced team uses highly-efficient GPR systems and analysing data.

At Cook Costello, we have two GPR systems, a 250 MHz and a 1000 MHz which is ideal to locate a large variety of subsurface targets. The GPR method works by emitting radar pulses into a material (soil, rock, concrete etc) that reflects off the different layers below the surface and then travels back up where it will be registered by the GPR receiver above ground. These reflections are produced when there is a contrast in the properties between the layers of the ground or the material being investigated.

Strong reflections are generally air, water or metallic objects; this makes GPR ideal for finding underground voids, utilities like power, or fibre cables, and buried man-made objects. Whether a target can be found or not will depend on its shape, size and depth. GPR operates at different frequencies, the higher the frequency, the higher the resolution but the lower the penetration and vice versa.

Our GPR systems can locate a variety of targets, such as:

  • Utilities
  • Identifying geological layers
  • Underground Storage Tanks (UST)
  • Unmarked graves
  • Concrete scanning
  • Subsurface voids
