Ground Penetrating Radar

Non-destructive testing of build structures is carried out mainly with high resolution Ground Penetrating Radar (GPR) antennas.

GPR can see into concrete pavements, tarmacadam roads, railway ballast, brick buildings and precast slabs to discover the steel mesh and grid structure inside – and detect possible faults and failure points.

GPR structural testing technology can be used on any concrete structure:

    • Balconies
    • Beams
    • Bridges
    • Ceilings
    • Columns
    • Pavement
    • Piles
    • Roads
    • Roofs
    • Slabs
    • Tunnels
    • Walls

GPR structural testing is non-destructive, and allows the detection of concealed objects – like reinforcement steel, post tensioning, cables, conduits and voids – without the need to break the concrete out, and reducing risk when concrete cutting or drilling is needed.

Trust Minerex Geophysics to gain full visibility of your concrete structures and deliver reliable information – enabling you to reduce risks and better manage your project site.


A concrete structural test is essential during construction to:

  • Reduce accident and injury risks,
  • Simplify concrete drilling, cutting, and coring,
  • Minimize damage to utilities, rebar, post-tension cables, pipes, and conduits,
  • Preserve structural integrity of concrete,
  • Avoid the cost of mid-project repairs.

Do I Need A Concrete Scan?

The answer is Yes, if:

  • You plan on cutting, coring or drilling existing concrete during construction.
  • You suspect a failure or weakness of an existing built concrete structure on your site or project.
