Spread 1 - Drilling PND provides an American Association of State Highway and Transportation Officials and American Society for Testing and Materials (AASHTO-ASTM) accredited Soils-Material Lab to characterize soil and rock in support of its designs. The Soils-Material Lab also includes a 230-square-foot temperature controlled “Cold Room” for processing and testing permafrost soils at in-situ Arctic temperatures. The lab is equipped to perform a full range of index tests and many advanced secondary testing protocols. PND’s Soils-Material Lab supports its geotechnical design work. PND prides itself on drilling methods, together with its drilling partners, to extract the highest quality samples possible.

The lab routinely performs the following ASTM and non-ASTM index texts:
  • Sieve analysis w/ wash
  • Hydrometer
  • Specific gravity
  • Moisture content
  • Visual classification
  • Atterberg limits
  • Unit weight
  • Modified proctor
  • Point load tests on rock
  • Soil salinity
  • Soil thermal conductivity
  • Soil electrical resistivity
