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

Aerial Photography and Videography

Aerial views provide unique, breath-taking perspectives, capturing assets, sites and landscapes as images, videos or photospheres. Perfect for reconnaissance surveys, settings assessments or promotional campaigns.

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.

Earth Resistivity Tomography (ERT)

Multiple earth resistance profile measurements are fused to create 2D sections and 3D profiles of electrical resistivity through the ground, commonly used to determine the depth of known features.
