Our laboratory complies with ASTM E329 and ISO17025, including provisions for personnel. Our company is regularly inspected by many organizations including AMRL, CCRL, Illinois DOT and IAS (ICC). We participate in proficiency testing with other laboratories nationwide in soils, concrete, aggregates, asphalt and other materials to ensure the quality of our work in the laboratory and in the field. Currently, 80% of our field technicians are certified by the American Welding Society and/or the International Code Council, allowing us to be one of only a few laboratories in the area able to supply the demand for Special Inspectors. Our supervisors are also accredited to these same high standards to ensure that proper supervision is provided.
