While most engineers normally operate in large dimensions, CTLGroup’s scientists and engineers can solve problems to the nanoscale. Our clients contract us to solve very complex failures, determine product defects, assist in developing new products or to provide routine third-party product verification.  Our scientist and engineers vary in disciplines from geology, civil engineering, material science, metallurgy, organic and inorganic chemistry.  Our personnel are highly trained, with 30% holding Ph.D. degrees. Our institutional experience with construction materials spans well over 100 years.
