Fondasol Géophysiques et Mesures

Our activities

Geophysical measurements

The Geophysics Unit employs the majority of the geophysical techniques used in geotechnics. We operate in France and abroad for public (EDF, RFF, Départemental Councils, Regional Councils, town councils, etc.) and private (consulting engineers, industries, architects, etc.) customers.

Principal problems addressed

  • MASW method (Niger)MASW method (Niger)
    Definition of geological models,
  • Determination of dynamic parameters (Vs30, Young’s modulus, etc.)
  • Determination of rippability limits and associated earthworks methods,
  • Looking for natural or man-made cavities, networks, buried objects, subsoil anomalies,
  • Investigation and characterization of the integrity of structures,
  • Determination of the length of foundations,
  • Detection of metal reinforcing,
  • Looking for leaks in dykes, dams,
  • Archæological research.
