Aggregate Geophysics: NGA provides geophysical services to the aggregate industry, assisting quarry operators in defining resources and planning operations prior to excavation. We can help you map and delineate sand & gravel deposits, optimize drilling locations, create volume estimates and determine depth-to-bedrock and rock rippability. Surface geophysical techniques are non-invasive, cost effective, and can be conducted prior to, or as part of the permitting process.
