Electrical Resistivity

Electrical resistivity survey is a long established method for mapping buried foundations, burial cairns, and walled enclosures.

These remains produce visible contrasts above the background resistivity of the undisturbed soil, and can be easily mapped using an array of electrical probes and appropriate data collection strategy.

The technique uses an array of electrical probes to inject an electrical current into the ground and measure resistance to the flow of that current as it passes through the underlying soil.

TARGET provides high resolution electrical resistivity survey to map the anomalies and associated remains within the study area. This is achieved using a modular system permitting wider electrode spacing for investigation of remains at depths from 0-1.4m.
