When materials fail, structures fail. WJE's materials scientists provide comprehensive consulting services for the evaluation of construction materials—both new and old. A full range of services in petrography, microscopy, analytical chemistry, organic and inorganic chemistry, and physical testing of materials are offered in WJE’s Janney Technical Center in Northbrook, Illinois, and branch office laboratory facilities in Austin, Texas, and Cleveland, Ohio.

The combination of comprehensive materials sciences expertise with engineering and architectural capabilities uniquely positions and qualifies WJE to deliver innovative yet sound solutions to construction materials problems. Using state-of-the-art evaluation methods, many of which were pioneered at WJE, the firm's materials scientists have a long history of performing foundational construction materials-related research and have solved thousands of construction materials problems, answering such questions as “Why did it fail?,” “How long will it last?,” and “How can it be fixed?”
