Concrete and Rebar Investigation

At Subscan we utilise the latest ground penetrating radar (GPR) technology to locate and measure structural reinforcement within elements of building structures.  These can include floor slabs, reinforced concrete and concrete beams.  Furthermore, it can detect voids within unusual structures, such as bridges.

Core sampling is a more traditional method, but it adds unnecessary cost, damage, and risk to a project.  By utilizing our scanning technology, we reduce the need for invasive techniques and provide a quick, easy service that minimises any disruption to businesses or the environment.

By understanding the location of reinforcement, the risk of striking the steelwork or any hidden objects during construction is reduced.  This will prevent injuries on site, equipment damage, or the deterioration of existing concrete structures.


  1. A wide range of non-invasive survey applications are possible, both internally and externally.
  2. Minimises any disruption to businesses or the environment.
  3. The method is less invasive than drilling and sampling cores to understand structure performance.
  4. Up to 800mm scan penetration depth provides high scan quality.
