Geophysical surveys enable underground structures and anomalies to be charted in a non-destructive way. The advantage of geophysics is that large areas can be covered in relatively short time frames thus leading to an optimized geotechnical campaign.

Providing geophysical services covering the three environments; land, intertidal and offshore environments enables G-tec to provide our Clients with one data set and model for their whole project.

Each of the environments mentioned above have their own set of specific investigative methodologies and challenges. G-tec has the ability to manage these as follows.


Land Geophysics:

  • Unexploded Ordnance (UXO) detection (EM and Magnetometry)
  • Refraction Seismics
  • Reflection Seismics
  • Borehole Siesmics
  • Electrical tomography

Marine Geophysics:

  • Magwing; Unexploded Ordnance (UXO) Clearance
  • 2D Reflection Seismics, single- and multichannel
  • UTSR: Refraction Seismics
  • Hydrography: Multibeam Echosounder and SideScanSonar
