The tool we deploy in the field depends on the objectives required in the office. Electrical Resistivity Tomography (ERT) - pictured in the mud pit - is a great tool where depth of impacts is required. Bedrock mapping, near-surface soil types, differentiating sands from clays, ERT provides a robust and simple method for imaging to depths of 30 m. Examples of other tools we employ...
Ground penetrating radar, refraction surveys, electromagnetic and electrical resistivity tomography.
