GROUND SURVEYS

Geophysical surveying services from the ground

GRM Gravimetry

Strong geophysical expertise

GRM provides ground-based geophysical measurement services that provide information from the first metres of soil to kilometres down into the bedrock. 

The methods are used to investigate the physical properties of the soil chamber, such as electricalal and magnetic properties, density and elastic properties.

We have a high level of expertise throughout the research process, a high regard for safety, efficiency and experienced staff. In addition, the company offers a very wide range of geophysical services.

  • Measurement of conductivity

    Exploration for conductive mineralisation

    Configurations: moving loop, fixed loop, multi loop

    Transmitters: 4 - 75 kW
