Meticulous at Every Step

Detailed. Committed. Ready. Our dedicated staff of engineers and technicians promote communication with the Contractor and a defined level of quality control.

Our staff utilizes construction procedures and standards of the American Society of Testing Materials, the American Concrete Institute, applicable State Transportation Departments, and other agencies as appropriate.

Laboratory Testing in Multiple Locations

Our full-service material testing laboratories are located in Hannibal, MO, and Burlington, IA. We are validated by the U.S. Army Corps of Engineers to perform material test methods, which include aggregate tests; bituminous tests; concrete tests; masonry, mortar, and grout tests; rock tests; soil tests; and spray fire-resistive material tests. Our Quincy and Galesburg locations also have laboratory facilities and field testing capabilities.
