Laboratory Testing: Soil and Aggregates

Paterson has numerous laboratory technicians capable of completing low to high complexity of soil and aggregate testing. Paterson ensures quality testing is completed on each sample with an emphasis on turnaround timeline.  We are certified to undertake Ministry of Transportation (MTO-LS Standards), City of Ottawa and other municipalities/counties, American Society of Testing Materials (ASTM) and American Association of State and Highway Transportation Officials (AASHTO) testing relative to the following service sectors.  With testing facilities in both Ottawa and North Bay Ontario, concrete laboratory certified to CSA Level 1 criteria in accordance to CSA A283, and asphalt laboratories certified by CCIL (Canadian Council of Independent Laboratories) Categories A, B, C, D and E.
