What does a geophysical survey tell you?

A geophysical survey measures contrasts in subsurface physical properties to help interpret buried features, geological boundaries and site conditions. Ambient’s geophysical offering combines methods such as ground-penetrating radar (GPR), electrical resistivity imaging (ERI), seismic, electromagnetic and magnetic surveys with the wider investigation.

Match the method to the target

  • Question Define the feature, depth range and investigation objective.
  • Method Review geology, access, interference and survey coverage.
  • Interpretation Relate the findings to borings, samples or other site information.

Geological & geotechnical questions

Sinkhole and karst evaluation, top-of-rock and void delineation, clay mapping, hydrogeologic evaluation and excavation conditions.

Environmental investigations

Investigate tanks, piping, buried debris and waste, landfill boundaries and patterns relevant to soil or groundwater assessment.

Structures & specialist surveys

Foundation and pile studies, borehole logging, concrete or pavement evaluation, marine surveys and aerial site mapping.

GPR, electromagnetic and magnetic methods

These methods can help locate buried features, utilities, tanks and metal debris. Target material, depth, soil conditions and site interference affect which method is suitable and how results are interpreted.

Resistivity and seismic methods

Electrical resistivity imaging investigates resistivity contrasts in soils and groundwater settings. Seismic methods investigate subsurface layering and dynamic properties. The survey professional selects the configuration and complementary verification.

Structural and non-destructive investigations

The published service range includes foundation evaluations, pile integrity testing, borehole logging, pavement and concrete thickness, rebar condition, deep-foundation or seawall length, and buried-foundation or reinforcement mapping.

Marine and aerial site information

Specialist applications include marine or lake bathymetry, sub-bottom profiling and submerged-object investigation, plus drone-based orthophoto, infrared and LiDAR site information. Confirm the method and deliverables needed for the project.

Geophysical interpretation / subsurface context

Connect the survey result with the site investigation

The published MASW example illustrates how a geophysical profile can identify a subsurface contrast for further evaluation. It is an interpreted survey result; investigation objectives, geology and supporting site information determine what the project team can conclude.

01 Define the target Start with the feature or condition the investigation must evaluate.
02 Combine evidence Coordinate survey results with available boring, sampling and site information.
03 Agree the outputs Set survey limits, interpretation needs and reporting format before fieldwork.

Prepare for mobilization

Scope the target, coverage and deliverable

A useful request describes the subsurface question as well as the area to survey.

  • Survey area and access

    Site plan, accessible boundaries, surface conditions, structures, traffic, known utilities and interference sources.

  • Investigation objective

    Target features, estimated depths, geology, available records and proposed follow-up borings or verification.

  • Data and reporting

    Required maps, profiles, interpretation, coordinate references, delivery format and schedule. Confirm specialist marine, aerial or structural requirements during scoping.
