Spread 1 - Drilling PND provides an AASHTO-ASTM Accredited Soils-Material Lab characterize soil and rock in support of our 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 our geotechnical design work; therefore the importance of high-quality work is understood by those involved in both the sampling and testing processes. PND prides itself on drilling methods, together with our 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 Resistvity
