GROUND SURVEYS
Geophysical ground surveys for exploration
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 bedrock, such as electrical 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.
