Electrical Resistivity Tomography for Rapid and Non-Invasive Soil Characterization – Selected Application Examples

This presentation will introduce the electrical resistivity tomography (ERT) method. It will discuss its advantages, limitations, and measurement procedures, as well as present selected case studies described in the literature, including studies conducted in the vicinity of development projects in Warsaw. The presentation will also include the authors’ own research results from an urban environment, whose aim was to investigate the geological structure to a depth of approximately 90 m below ground level. It will be demonstrated that the ERT method enables the rapid acquisition of high-quality data, particularly useful in the case of subsoil requiring precise differentiation between sandy and clayey layers, characterized by a distinct resistivity contrast. For this reason, this technique is widely used in modern geotechnical engineering, allowing trenchless designs to be adapted to actual soil and groundwater conditions as early as the initial stages of a project.
