Service basis
What this service supports
- Client need
- Subsurface uncertainty affecting foundations, slopes, groundwater targets, utilities, or project planning.
- Good fit when
- Non-invasive subsurface screening could help focus a wider investigation program.
- Conditions need to be compared between limited boreholes, exposures, wells, or other control points.
- A survey target has a plausible physical contrast and the site can support a suitable acquisition layout.
- What you gain
- Inferred subsurface contrasts that can guide boreholes, sampling, monitoring, or other confirmation work.
- Visible QA context and limitations so interpreted sections are not treated as direct geological observations.
- Useful inputs
- The survey target, decision to be supported, and desired investigation depth or scale.
- A site plan, coordinate reference, and available geology, borehole, well, or utility information.
- Access, ground-surface, cultural-noise, safety, and line-layout constraints.
- Approach
- ERT, MASW, GPR, VES, TEM, and survey design selected for the target and site conditions.
- Typical outputs
- Processed sections, QA notes, interpreted contrasts, and practical follow-up priorities.
- Professional limitation
- Geophysical responses are inferred conditions and require geological, borehole, sampling, pumping-test, or monitoring confirmation where applicable.
