Important notice

GeoExpert AG has dissolved its field equipment for seismic data acquisition as of 1 September
2023 and will no longer offer this service.

Due to his advanced age, Walter Frei (founder and main shareholder) has decided to pass on his
experience from over 400 practical seismic surveys during his six years in the oil industry and the
subsequent 35 years as Managing Director of GeoExpert AG.
Walter Frei now offers his know-how in technical and administrative project planning and
management, in the acquisition and processing of engineering seismic data and in their geological
interpretation as a proven expert.

The pioneering hybrid seismic method introduced to the market by GeoExpert AG in 2000 has
been continuously improved since then. The inclusion of this method in the loose cooperation
with GEO ALPS Consulting SA, based in CH-6834 Morbio-Inferiore, which exists since 2018, thus
enhances its range of services in the following fields of engineering geology:

  • General geotechnical clarification of ground stability and cavity detection
    (non-invasive dynamic derivation of rock mechanical moduli, e.g. Young’s E-modulus sections)
  • Hydrogeology / groundwater prospection
  • Natural hazards / slope instabilities
  • Mapping of structures with geothermal potential at intermediate depths (up to 2500 m)
  • Environmental issues / landfill investigations

As a freelancer for GEO ALPS Consulting SA, Walter Frei (w.frei@geo-alps.com) offers his many
years of experience in high-resolution seismic data acquisition and processing.
