Laboratory Testing

Providing support for our geotechnical engineering and construction monitoring divisions, Triad maintains complete laboratory facilities where tests are conducted by experienced technicians under the supervision of professional engineers. Our laboratory technicians hold many applicable state agency certifications. Materials tested include soil, concrete, aggregate, asphalt, rock and sprayed-on fireproofing. Our testing labs routinely participate in national quality control programs administered by AMRL and CCRL which follow AASHTO and ASTM testing procedures.
