This technique has been successfully applied by Douglas Partners in a wide variety of environments. Typical applications include:
- Layer mapping
- Depth to bedrock
- Landfill Investigations
- Void mapping
- Groundwater and contamination investigations
Mapping the continuity and thickness of a clay layer along a proposed highway route was considered necessary to help assess the likelihood of future subsidence. The models showed a strong correlation with nearby boreholes.
Mapping a landfill pit boundary was required for a proposed development. Resistivity contrasts between the landfill material and the underlying geology made delineation of the landfill boundary and thickness possible.
Vertical Electrical Soundings
Vertical Electrical Soundings provide a 1D electrical profile of the subsurface, commonly used in earthing design for lightning protection, electrical substations, power lines and pipelines.
