Geophysics
Geophysical Surveys for Improved Ground Understanding and Risk Reduction
Engineering geophysics extends ground understanding between boreholes and test pits and is a key tool in developing reliable ground models across large or complex sites. At WML, geophysical surveys are planned and interpreted by geotechnical engineers to ensure results directly support investigation planning, foundation design, void detection, remediation, and infrastructure development.
We use geophysics to reduce uncertainty between intrusive investigation points and to improve confidence in subsurface interpretation. This includes applications across foundation design, mining environments, tailings and embankment projects, and infrastructure investigations where broader ground coverage is required.
What We Offer
Ground Penetration and Void Detection
We apply ground penetrating radar and LiDAR-based methods to assist in detecting buried features, mapping void geometry, and supporting remediation design in complex environments.
Resistivity and Subsurface Imaging
Electrical methods are used to map subsurface variability, identify voids and historical workings, interpret seepage pathways, and support earthing design requirements.
Seismic Methods and Ground Profiling
We use seismic techniques to determine ground properties including shear wave velocity, dynamic stiffness, depth to rock, and weathering profiles. This supports foundation design and excavation assessment.
Experts for Western Australian Environments
We apply geophysical methods across a wide range of Western Australian projects, from mining and tailings investigations through to major infrastructure developments. Our experience in WA ground conditions allows us to tailor survey methods to site constraints and project requirements.
Geophysics is most effective when integrated with drilling, CPT, and laboratory testing. We routinely combine these datasets to build robust ground models that support practical engineering decisions across all project stages.
We also streamline delivery by combining geotechnical, geological, and geophysical scopes into a single mobilisation, reducing cost and improving project efficiency.
