Proving that ground is fit-for-purpose

Proving ground to be competent for planned engineering uses can help to prevent subsequent, dramatic remedial measures. Zetica provides rapid non-invasive surface and borehole geophysical methods to characterise materials and detect unpredictable features before these become costly, time-consuming problems.



  • Locate voids and sinkholes
  • Locate mineshafts and adits
  • Map bedrock depths
  • Map bedrock rippability
  • Map fractures and identify weak zones in bedrock
  • Locate shallow sand and gravel deposits
  • Map groundwater surface and flow paths
  • Determine unknown depth of foundations
  • Evaluate structures – bridges, weirs
  • Evaluate pavement - roads, runways
  • Detect buried hazards on brownfield sites
