Geophysical

Whether planning new construction or evaluating subsurface features, costs and risks may be reduced by using the Ninyo & Moore Geophysical Services Team.  Geophysical surveys help guide the placement of expensive excavations and testing programs, and provide supplemental information from locations between borings and excavations and may result in cost savings. Developing geophysical survey results prior to design and construction activities can also help avoid costly contractor change orders.

Geophysical surveys can be used to:

  • Characterize geology
  • Evaluate depth to bedrock
  • Evaluate rippability
  • Evaluate shear wave velocity
  • Evaluate soil corrosivity
  • Locate faults
  • Locate rebar in concrete
  • Locate voids
  • Map shallow stratigraphic units
  • Map underground utilities
  • Map landfill boundaries
  • Monitor ground vibration
  • Locate buried storage tanks
  • Locate underground pipes
  • Locate previously excavated areas
  • Locate buried drums
  • Locate buried ferromagnetic objects
  • Locate buried non-ferrous objects
  • Delineate drilling-mud pits
  • Map landfill leachate plumes
