Materials Testing

Shelby’s experienced engineering and technical staff can provide laboratory and field testing of construction materials and quality assurance/quality control (QA/QC) testing during construction on projects ranging from simple one-time visits (such as a single concrete test) to long term, complicated projects (such as the redevelopment of a historic structure).

Field Testing

  • density testing of soil and granular materials
  • testing of fresh and hardened concrete
  • foundation installation monitoring
  • subgrade assessments
  • frost inspections
  • rebar inspections
  • asphalt and concrete coring
  • Impact hammer (Schmidt hammer) testing
  • Soil and groundwater sampling
  • dynamic cone penetrometer (DCP) testing
  • gravel crusher control

Laboratory Testing

Our laboratory is well equipped to conduct construction materials testing on soil, aggregates, asphalt, and concrete to relevant CSA, ASTM or AASHTO CCIL standards.

  • Compressive and flexural strength of concrete
  • Compressive strength of mortar, grout or shotcrete
  • Moisture-density relationships of soils and aggregates (Standard Proctor or Modified Proctor)
  • Gyratory compaction analysis of ACP samples (Superpave)
  • Asphalt content determination
  • visual classification of soil and aggregates
  • Atterberg limit testing (plasticity testing)
  • grain-size analysis (sieve analysis and hydrometer)
  • Specific gravity determination
  • organic content
  • unconfined compressive strength
  • California Bearing Ratio (CBR) determination

Specialty Testing

In addition to routine testing services, Shelby offers several more specialized testing services

  • Floor Flatness Testing (to ASTM E1155)
  • Relative Humidity Testing (to ASTM F2170)
  • Radon Testing by Canadian National Radon Proficiency Program (C-NRPP) certified Radon Professionals for both radon measurement and radon mitigation
  • Pull-off testing to determine bond strength of toppings, overlays or floor tiles
