Ground Penetrating Radar

Ground Penetrating Radar (also known as Ground Radar, Ground Probing Radar, GPR and Surface Penetrating Radar) provides a non-intrusive and non-destructive method of surveying the Subsurface and Concrete Imaging. It is a highly cost effective non-disruptive technique, offering a rapid means of obtaining subsurface information from a variety of materials including soil, concrete and asphalt.

Ground Penetrating Radar is a geophysical technique originally developed for mapping geological features, but it is now increasingly used for Civil Engineering applications. GPR is particularily useful for:

  • Concrete Imaging (including rebar mapping)
  • Concrete floor slab surveys
  • Utility Surveys
  • Building investigation
  • Chimney flue location
  • Void detection
  • Underground tank location

Sandberg LLP offers a comprehensive Ground Penetrating Radar site survey service, including data processing, analysis, interpretation and reporting.

Floor Slab Surveys

GPR ND concrete floor slab survey

Ground Penetrating Radar (GPR) offers a very cost effective way of assessing concrete floor slabs. Where as built records are not available GPR can be used to determine the floor slab construction...
