PND's trained geotechnical engineering and testing staff is also capable of performing the following:

  • Cone penetrometer tests
  • Dynamic cone penetrometer tests
  • Downhole vane shear tests
  • Ground-penetrating radar and electrical resistivity tomography surveys
  • Subsurface ground temperature profiling
