Our Unique Foundation and Promising Future


CTLGroup originated a century ago as the cement and concrete technology Research and Development Laboratories of Portland Cement Association (PCA) in 1916. How have we changed? In some ways, we haven’t.  We are still thought leaders and problem solvers. We are still engineers, architects, scientists, and consultants. As the world around us has changed, we have evolved with it to continue to meet the needs of our clients.


In the 1960s, present-day CTLGroup began providing consulting services for applied research projects, continuing to expand its engineering consulting services through the 1980s. In 1987, CTLGroup was incorporated as Construction Technology Laboratories, Inc., a wholly-owned subsidiary of PCA, and in 2005 began doing business as CTLGroup.

Our accumulated knowledge from our unique beginning has allowed us to offer new areas of practice and specialization which we have been able to pass on to our clients in the form of added services, technical expertise, and expanded practice areas.

CTLGroup is an internationally recognized expert consulting engineering and materials science firm, providing engineering, architecture, and scientific testing to our clients across the globe. Our engineering expertise is complemented by one of the largest and most comprehensive private materials and structural testing laboratories in the world. The CTLGroup experts can address problems from the materials and structural perspectives to deliver an integrated solution.
