Laboratory Soil Testing

Robinson Noble maintains an in-house laboratory equipped to evaluate the properties and characteristics of soil, completed in accordance with ASTM standards. Properly describing the soil allows our engineers to scientifically analyze the planned improvements with the underlying soil and groundwater conditions.

We commonly complete soil tests such as:

  • Sieve and hydrometer analysis

  • Moisture content

  • Density

  • Proctor tests

  • Atterberg limits

  • Sand equivalent

  • Specific gravity and absorption

  • Direct shear

  • Consolidation

  • Hydraulic conductivity/permeability
