Geophysics

Non-destructive investigation methods to image the subsurface over large areas, complement geotechnical boreholes and reduce uncertainty.

Why this service?

See below the surface, without digging.

Geophysics quickly covers large areas and guides boreholes to where they are truly useful: less uncertainty, lower costs.

Services offered

  • 01Electrical resistivity imaging (ERT tomography)
  • 02Vertical electrical soundings (VES)
  • 03Soil resistivity for earthing systems (solar plants, substations, buildings)
  • 04Seismic refraction and surface waves (MASW): ground stiffness and layer thickness
  • 05Ground-penetrating radar (GPR): cavities, utilities and shallow interfaces
  • 06Electrical and magnetic methods for mineral exploration and groundwater search
Methods & standards

Recognised methods, reliable data.

Recognised geophysical survey methods, systematically calibrated against available geotechnical boreholes or wells.

Frequently asked questions

Have a question?

Why combine geophysics and boreholes?

Geophysics images large areas; boreholes calibrate it at precise points. Together, they give a reliable picture of the subsurface.

Why measure soil resistivity for a solar power plant?

It is used to design the earthing of electrical installations: panels, substations and buildings.
