Resistivity

Resistivity field work

Fender’s resistivity surveys apply a low voltage to the ground via electrodes to measure variations in the composition of the subsurface.  Acquired data is processed to produce cross-sections of the subsurface which depict soil layer thicknesses and interfaces as well as other physical properties at depth.  This data can be employed in the planning of geotechnical projects.  Resistivity surveys are utilised to:

  • Locate abandoned mineshafts and mine infrastructure
  • Measure water table depth and delineate bedrock
  • Delineate landfill sites and leachate contamination
  • Detect sinkholes and voids
  • Mapping buried waterways
  • Identify potential fracture zones
