MATERIALS TESTING

Quality monitoring can be the most critical dimension in a construction project.  To ensure that design criteria are met, unknown conditions are detected and potentially costly setbacks and dangers are avoided, SJB provides a system of controls through testing and inspection procedures that are essential to the stability and performance of the project.

SJB is a member of the American Council of Independent Laboratories (ACIL) and is inspected by the Cement and Concrete Reference Laboratory (CCRL) and the Army Corps of Engineers.  Our technicians maintain numerous certifications including ICC (concrete masonry, and fireproofing ), NICET Level I-IV, ACI Field Technician Grade I and Grade II Construction Inspector, Certified Welding Inspector (CWI) and Concrete Laboratory Technician Grades I and II.  In addition, each technician has been properly trained and certified in the operation of nuclear density gauges.
