The team sees projects through from start to finish, checking compliance, and overall project issues. If challenges do surface, the team has reliable response mechanisms to assist clients with resolutions. Clients stay informed about testing results with readably available electronic delivery.
The construction materials testing group’s credentials, backed by our ongoing commitment to client service and satisfaction, make us a Mid-continental leader in the areas of concrete, asphalt, steel, soils and other construction materials testing. Our field representatives hold certificates from ACI, NICET, ASNT and AWS. Our St. Louis, Collinsville, Overland Park and Memphis testing laboratories are AASHTO/AMRL-CCRL and Army Corps of Engineers approved, our St. Louis lab is MoDOT approved and Collinsville is IDOT approved for aggregate and concrete testing.

The CMT group has played an integral role in the successful completion of many landmark construction projects and is recognized for providing quality, reliable service to contractors, owners, engineers and architects in Missouri, Illinois, Kansas and Tennessee. The St. Louis CMT group surpassed 5,000 days without a lost time accident on July 10, 2014, a monumental safety achievement.
