NORCAL provides non-invasive geophysical surveys from the ground surface as well as geophysical logging in boreholes to provide images or models of subsurface conditions. Our geophysical services include carefully defining specific survey objectives, designing a cost-effective approach to meet those objectives, acquiring high quality geophysical data using state-of-the-art instrumentation, analyzing the resulting geophysical data using leading edge computer processing and inversion techniques and providing our interpretation of the results. We routinely provide our services to geologists, geotechnical engineers, hydrologists, environmental engineers, archeologists, land planners, government agencies, and property owners throughout the United States and in several foreign countries. The information we provide is often a critical component in the planning, design and implementation of studies involving:
- Vital Infrastructure such as tunnels, roads, pipelines, powerplants, landfills, water supplies, airports, dams, and levees.
- Earth Resources such as groundwater, quarry rock, sand and gravel, and other earth materials.
- Geologic Conditions such as buried stream channels, faults, landslides, sinkholes and other voids, rock conditions, and groundwater movement.
- Underground Objects such as buried drums, underground tanks and utilities, buried debris, historical and archeological features, and forensic evidence.
