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
