Georisorse Italia started Geophysical Prospecting in 1983, carrying out studies, planning, data acquisition, data processing and specific interpretation to obtain the required information. All activities are carried out using the methodologies and technologies of STATE OF THE ART..

Over the years, Georisorse Italia has carried out some 2,000 projects in Italy and abroad, producing research projects in water prospecting, archaeological studies, studies geotechnical engineering for the construction of motorways, tunnels, railways, subways, bar-ra-gees and pipelines. protection against pollution, preservation of environmental resources, slope stability and seismic assessments

VS30ÉVALUATIONPARAMÈTRE Consistent with the new Italian standards for construction

work, NTC2008, it is mandatory to set the value of parameter Vs30 to fix

the CATEGORY of the FIELD FOUNDATION This parameter must be verified in situ using specific seismic

survey techniques in holes or on the surface and with active or passive measures.

GEORISORSE ITALIA IS QUALIFIED to perform such an activity and can provide

both experienced staff and the necessary equipment.
