How GPR Concrete Scanning Works

Using the latest Ground Penetrating Radar (GPR) technology and techniques, Australian Underground Search can locate hidden features within the concrete.



We use GPR to determine post tension cables depth and location, then map these concrete reinforcements to ensure they are not damaged when cutting or drilling is necessary on the slab. This technology can also calculate the depth of the cables as needed.


In addition, GPR can be used to locate rebar, conduits, underground storage tanks, utilities and even unmarked graves in both soil and concrete. This provides critical information on not just support structures but utilities and other obstructions.

The Information You Need 

Moving forward on your project without having accurate sub-surface data may jeopardise machinery, compromise structural integrity or pose risks to operators. Our experienced team can interpret any detected anomalies to determine what is located within concrete structures.


Using GPR technology we can scan for steel reinforcement, post-tension cables, live power, sewer and water pipes, metallic and non-metallic pipes, phone, data and fibre-optic cables.


An example of the sub-surface data that can be provided includes:

  • thickness of the slab
  • reinforcement location and pattern
  • size of reinforcement
  • position of footings or beams
