DEPENDABLE GEOTECHNICAL LABORATORY TESTING IN Markham
Fisher Geotechnical Laboratory team partners with independent professionals and the general public across the province to help analyze geotechnical samples and provide support with sample collection. If you require support with the investigation, identification, or collection of samples, please contact us directly.
Our geotechnical services are divided into three categories:
SOIL AND AGGREGATES: SOIL CLASSIFICATION, GRADATION,
PROCTOR, AND PLASTICITY
Soil Tests are typically about soil classification and include sieve analysis, hydrometer, plasticity (Atterberg), and specific gravity tests. The result is used to predict the mechanical and chemical behaviour of the soil sample. The test of the percentage of organic content in the soil is also available for organic soil samples.
Aggregate tests include sieve analysis, proctor test, and percentage of crushed asphalt coated and flat and elongated particles. In reports, results are compared with OPSS regulations of sample material. The Proctor test result is the reference

number for backfill and engineering fill tests on site.
CONCRETE, MORTAR, AND GROUT: SLUMP, AIR CONTENT, AND COMPRESSIVE STRENGTH
Concerns with fresh concrete include uniformity, workability, and consolidation. For fresh concrete, tests typically include slump, air content, and temperature. Once the concrete is self-consolidated, the slump test is changed to the slump flow test.
Quality concrete needs a proper mix of materials and environmental and workmanship conditions. Tests play a certain role in ensuring that materials used in a structure meet the specification requirement. The compressive strength test is the most important for hardened concrete, mortar, and grout samples.
ASPHALT: HOT MIX FULL MARSHALL, EXTRACTION, AND GRADATION
Quality asphalt mixtures need a proper combination of material and workmanship. No amount of proper workmanship can compensate for poor material quality. Tests are necessary to determine if the materials meet the project specifications. A Full Marshall test for hot mix asphalt includes extraction, gradation, asphalt cement content, bulk relative density, maximum relative density, and Marshall flow test.
