What Is an Urban Geophysical Survey? Methods, Uses, and Applications | multiVIEW Locates Inc.

Urban subsurface conditions are complex—and understanding them requires more than a single tool. At multiVIEW Locates Inc., #geophysicalsurveys are designed around the project, not the equipment. Each survey is carefully planned to match site conditions, survey objectives, and the level of detail required to support confident decision-making. Our geophysical services support environmental and archaeological investigations, as well as a wide range of other subsurface studies in urban and developed environments. We apply multiple, complementary geophysical methods, including: Frequency-Domain Electromagnetics (FDEM) to identify changes in soil conductivity and resistivity. These variations often reflect differences between native and foreign soils and may be associated with moisture changes, fill materials, or impacted ground conditions. Time-Domain Electromagnetics (TDEM) when conductive targets are a priority. This method is commonly used to locate underground storage tanks and other buried metallic features, while also supporting broader investigations involving conductive subsurface conditions. Ground Penetrating Radar (GPR) for high-resolution imaging of subsurface materials. GPR detects contrasts in subsurface properties and is especially effective for soil evaluation, identifying foreign materials, mapping bedrock depth, and defining subsurface structure. Seismic methods, where required, by measuring shear wave velocity. Seismic data provides insight into soil stiffness and strength while helping define bedrock topography and subsurface layering. By integrating these technologies, multiVIEW delivers a clear, reliable understanding of subsurface conditions—supporting informed planning, design, and investigation decisions across a wide range of urban projects.
