Earth Resistance (ER)

Measures the difficulty of passing an electric current through the ground. Effective for detecting features with different moisture content from the surrounding soil, such as foundation remains and ditches.

This technique measures the difficulty of passing an electric current through the ground. Effective for detecting features with different moisture content from the surrounding soil, such as foundation remains and ditches. We deploy a multiplex probe system, which can easily be configured to collect data at different probe separations to provide different depths of investigation according to the requirements of your project.

Our techniques

Learn more about the techniques that we use.

Aerial Reconnaissance

Incorporating aerial imaging during ‘walkover’ surveys extends the visual range of the surveyor, allowing reconnaissance to be carried out more safely and efficiently, with vastly more informative visual outputs.

Ground Penetrating Radar (GPR)

Measures the travel time of reflected high-frequency electromagnetic radiation. Effective for detecting abrupt interface changes and voids, for example foundation remains, graves, burial chambers and cellars.

Electromagnetic Conductivity (EM)

Measures the ease of which current flow can be induced in material. Effective for detecting conductive features, such as geomorphology and subsurface landforms, ditches and earthworks.
