When concrete mix designs and other building materials need an independent opinion, AET's Petrography Group can analyze materials produced or used for construction, transportation systems or product development.

We offer nationally recognized expertise in materials used for airfields, roadways, foundations and structures for commercial, industrial, agriculture or government use.
