Soils & Aggregates Laboratory Services

Soils and aggregates (gravels) are used in structural foundations or as constituents in concrete and asphalt. A variety of tests are performed to determine the suitability of the soil and aggregates used in construction. The testing of soil and aggregates is part of our core services and we offer a comprehensive list of tests that includes the following (but not limited to):


  • Aggregate Freeze / Thaw
  • Alkali Reactivity
  • Bulk Density
  • California Bearing Ratio
  • Chemical Composition
  • Clay Clumps
  • Deleterious Materials
  • Durability of Coarse Aggregates
  • FA Angularity
  • Fracture Count
  • Freeze-Thaw Salt Scaling
  • Hydraulic Conductivity
  • Hydrometer
  • Infiltration Test
  • Linear Traverse


  • Los Angeles Abrasion
  • Micro Deval
  • Moisture
  • Organic Content
  • Organic Impurities
  • Permeability
  • Petrographic Analysis
  • pH
  • Plastic Index (Atterberg)
  • Porosity
  • Quartz Equivalency
  • Resistivity
  • Sand Equivalent
  • Specific Gravity & Absorption
  • Splitting Tensile
  • Sulphate Soundness

Mobile Laboratory Services

Metro Testing + Engineering can provide on-site technical support for materials testing with the use of our fleet of mobile laboratories and trailers making them cost-effective and ideal for remote locations or long-term projects. Our mobile laboratories are compliant to CCiL Certification and operate under the same requirements as our fixed laboratory facilities so the test results can be relied upon with the same level of confidence. Our mobile laboratories have been used in large infrastructure projects such as airports, hydroelectric dams, remote highways, and major capital industrial development.
