| Description | CTLGroup originated over a century ago as the cement and concrete technology Research and Development Laboratories of Portland Cement Association (PCA) in 1916. Although we started as R&D, we were started by engineers and scientists. How have we changed? In some ways, we haven’t. We are still thought leaders and problem solvers. We are also 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. |
