In Bunbury’s coastal and alluvial setting, geophysics provides non-intrusive subsurface intelligence where the Swan Coastal Plain meets lateritic and limestone formations. Our methods address local challenges such as variable groundwater, karstic cavities, and soft sediments that directly influence foundation design under Australian Standard AS 1726. High-resolution [Ground Penetrating Radar](ground-penetrating-radar) maps shallow utilities, rebar, and voids, while [shear wave velocity](shear-wave-velocity) profiling via MASW delivers VS30 values critical for seismic site classification consistent with AS 1170.4.
These surveys support residential subdivisions, commercial developments, and infrastructure upgrades where borehole data alone is insufficient. Complementing the above, [HVSR microtremor survey](hvsr-microtremor-survey) rapidly evaluates natural period and resonance risk across larger footprints. Whether for pre-purchase due diligence or detailed design, our integrated approach reduces uncertainty and targets intrusive investigation where it matters most.
