The Construction Materials and Geotechnical Testing Laboratories at our Dayton and Toledo, Ohio locations perform physical and chemical testing on a wide variety of construction materials: soil, aggregate, rock, coal refuse, waste streams, concrete, masonry, asphalt, roofing, and other construction materials.

Testing also is performed in the laboratories at our Lexington, Kentucky and Springfield, Illinois locations.

Stringent quality assurance and quality control procedures provide results our geotechnical engineers can rely on as they consider recommendations for your site. And that means peace of mind for you.
