terrain conductivity data can be acquired rapidly with high data density


Various geophysical methods are utilized according to the specific conditions being tested. Variables include the nature of the target, ambient subsurface conditions, surface settings, access and permitting. Our acquisition, processing and interpretation capabilities include: 

  • Ground Penetrating Radar
  • Seismic Refraction
  • Seismic Reflection
  • Shear Wave Seismic
  • Surface Wave Seismic
  • Parallel Seismic
  • Gravity 
  • Magnetic Gradiometry
  • Resistivity
  • Electrical Conductivity
  • Borehole: Shear Wave, P-Wave, Radar, Temperature, Gamma Ray, Fluid Flow
  • Bathymetric Surveys
Our professional staff has applied various geophysical methods to a variety of applications
  • regional hydrogeologic characterization for resource development & litigations support
  • karst mapping and void detection for dams, tunnels, roadways, buildings
  • historical burials and missing persons surveys
  • top-of-bedrock surveys for golf course developments, tunnel alignments, aquifer delineation
  • detection of coal mines, buried foundations, vaults, voids, conduits
  • archeological investigations
  • dam seepage, sub-slab erosion, entombed trestles, timber cribbing
  • confirmation of presence and depth of timber piling
  • delineation of contaminant plumes
  • lake bottom mapping to develop stage-storage curve
  • bedrock fault and fracture mapping
  • rebar and void mapping in Melan Arch bridges, floor slabs and masonary walls
  • pavement quality mapping of international airport taxiway
  • confirmation of presence/absence of structural steel and grouting
