We participate in the AASHTO Materials Reference Laboratory program to actively gauge our performance. We also participate in ASTM’s Cement and Concrete Reference Laboratory program.
Our technicians have received on the job training, certification and accreditation from the American Concrete Institute (ACI) and the National Institute for Certification in Engineering Technologies (NICET). We follow the American Society for Testing and Materials (ASTM) procedures, including current developments within the construction industry.
