Geophysics

Ninyo & Moore offers a wide-array of specialty services to provide crucial data for engineering and construction projects. The use of geophysical services can reduce or eliminate the need for costly excavations, core holes, and bore holes, and can provide data coverage for large areas, reducing unknown factors and lowering project risks and costs.

Our state-of-the-art geophysical exploration can tailor a survey, utilizing the methods listed below, and has contributed cost savings to numerous high profile private and public sector projects, including dams, roadways, bridges, airports, mines, military facilities, and other projects.
