Geophysical Investigations

Geotec S.p.A. uses surface and downhole geophysical surveys in civil engineering showing particular expertise in data acquisition and processing.

Geotec carries out:

  • Seismic refraction surveys with body waves
  • MASW surveys – Multi-channel Analysis of Surface Waves
  • Downhole seismic surveys
  • Crosshole seismic surveys
  • Microtremor analysis using the Nakamura HVSR method (Horizontal-to-Vertical Spectral Ratio)

These surveys allow us to:

  • Define a seismo-stratigraphic profile of the investigated area
  • Determine soil physical properties and dynamic properties
  • Define a seismo-stratigraphic profile of the investigated area
  • Determine the Vs30 parameter for site classification according to new Technical Construction Norms in Italy (NTC 2008).
