Tetra Tech maintains a state-of-the-art materials practice that brings a high level of expertise and materials support to every project.

We provide construction materials engineering, inspection, testing, quality control, and quality assurance services to local government and provincial public works departments (roads, bridges, and schools), the land development industry (residential, commercial, industrial, and recreational), and the resource and mining industries (wind projects, substations, transmission lines, refineries, and dams). Tetra Tech has introduced innovative equipment and engineering methods that have advanced materials technology.

We provide construction monitoring and laboratory testing for aggregates and soils, asphalt, and concrete. Other specialty services include:

  • Soil permeability testing for liner construction and design
  • Post-construction concrete evaluation and analysis
    • Forensic failure analysis for Portland cement concrete structures, including slab-on-grade slabs, concrete pavements, bridge structures, and buildings
    • Sidewalk failure investigations
    • Corrosion half-cell potential for reinforced concrete structures
    • Moisture potential of concrete slab before flooring installation
  • Parking lot evaluations
  • Pavement condition investigations
  • Floor flatness testing
  • Full cold-room facilities for frozen materials testing: strength, creep, thaw consolidation, thermal conductivity, and frost heave
