Geophysics

We use geophysics to locate and identify subsurface features. These are non-invasive techniques, meaning there is minimal impact to the study site, with little or no drilling involved. That also means saving time and money on any project.

Geophysical services:

  • Subsurface Utilities (SUE), Utility location and mapping
  • Underground Storage Tanks (UST) location and mapping
  • Pre-drilling structural member locations (post-tension, rebar, concrete scanning, etc)
  • General subsurface and subfloor explorations
  • Water well and septic tank locations
  • Depth-to- bedrock maps

Technologies offered:

  • Seismic Refraction Tomography
    • Shallow seismic refraction tomography gives insight into subsurface materials
      • Ripability of subsurface rock
      • Depth to bedrock mapping
  • Ground Penetrating Radar (GPR)
    • Mala Geosciences’ Shielded antennas, most commonly used for locating and mapping subsurface utilities or archaeology sites:
      • 160 MHz HDR
      • 250 MHz RAMAC
      • 500 MHz RAMAC
      • 1200 MHz HF (for concrete scanning and rebar location)
    • Mala Geosciences’ Unshielded antennas, used primarily for environmental and geological investigations:
      • 50 MHz
      • 100 MHz
      • 200 MHz
  • Magnetometers
    • Geometrics Fluxgate magnetometer
      • used for mapping terrestrial magnetic features, such as buried landfills, etc
    • Schonstedt Heli-Flux Magnetic Locators
      • used for finding small-scale magnetic features, such as well casings or property corners
  • Terrain Conductivity
    • Geophex GEM2 terrain conductivity meter
      • for mapping terrestrial or freshwater features
  • Echosounder
    • Seafloor Systems Hydrolite Single Beam Echosounder
      • for hydrographic surveying inshore and nearshore, water depths between 1′ and 200′
