Providing Advanced Testing + Forensic Capabilities For Construction Materials

Thorough testing and analysis on construction materials is sometimes needed before, during and after construction to ensure a structure’s integrity and safety. Our accredited and independent Materials Laboratory houses state-of-the-art equipment for standardized and specialty testing and applied research. The laboratory provides chemical and physical testing and petrography for aggregates, cement, mortar, concrete and other construction materials.


We conduct standardized and specialized testing of the chemical and physical properties of Portland cement, supplementary cementitious materials and other finely divided materials providing information concerning:

  • Strength
  • Soundness
  • False Set
  • Composition
  • Time of Set
  • Sulfate Resistance
  • ASR Mitigation
  • Absorption
  • Shrinkage
  • Fineness


We conduct standard and specialty testing for concrete construction materials providing information concerning:

  • Freeze Thaw
  • Salt Scaling Resistance

Petrographic Services

Petrographic methods combine visual analyses using stereo, petrographic and scanning electron microscopes to examine and evaluate the optical properties and microstructural characteristics of the materials

The information from a petrographic analysis is regularly used to identify causes of distress and deterioration in materials, as well as predict future performance of the materials, and can aid in the evaluation of several issues, which include, but are not limited to:

  • Surface Scaling
  • Delamination
  • Improper Finishing or Curing Techniques
  • Discoloration of Staining
  • Cause of Cracking Distress
  • Freeze-Thaw Deterioration
  • Corrosion of Reinforcing Steel
  • Aggregate Popouts
  • Long Strength Results
  • Cement-Aggregate Reactions
  • Chemical Attack
  • Mix Design Verification
  • Coating Failures
  • Fire-and-Heat Related Damage
