Geoelectrical profiling

The electric resistivity profiling method uses the same type of arrays as in the vertical electric sounding (VES), just that in this case the interest is concentrated on several levels of depth. There for, there are arrays conceived with fixed distances between the electrodes so the measuring technology becomes simple and fast, the number of operators is smaller, the costs are smaller and the results can be visible immediately.


Geoelectrical profiling is ideal when we need to survey for shallow depth ground properties but on long distances. It is successfully used in determining soil contamination (for pipe protection, in agriculture, etc.), determining depth to bedrock, discontinuities in mechanic properties of rocks (useful in designing pipe and cable diggings), and tracking of pollutants. The method has new applicability in engineering geophysics.

Applications of geoelectrical profiling method:

  • Aquifer description
  • Bedrock depth
  • Mapping geological boundaries
  • Identification of fractures and fissures
  • Identification of fractures in the bedrock
  • Mapping of sand and gravel deposits
  • Sol / Layer unconsolidated
  • Mineral Exploration
  • Geological mapping
  • Mapping groundwater depth
  • Mapping spots brine
  • Groundwater Contamination
  • Inorganic pollutants leak detection
  • Leaking landfill
  • Maps of saline soils
  • Intrusion of salt water
  • Characterization of buried waste
  • Identification and mapping of leaks in tanks
  • Delimitation disposition pits / trenches
  • Identify wells
  • Old settlements
  • Old battle fields
  • Cemeteries
  • Historic structures
  • Historical complex
  • Observation posts
  • Archaeological battlefields
  • Measurements taken before and after dredging
  • Depth mapping rocks
  • Rock fracture detection
  • Tunnels , bridges or pipe route
  • Sedimentation studies
