Kleinfelder laboratories perform common and advanced tests that assist owners, engineers, designers, and builders with timely information pertaining to the quality and characteristics of various materials used in construction.

We test soil, aggregate, rock, bituminous materials, concrete, masonry and steel; either independently or in support of our geotechnical, construction observation, and materials engineering services.

Located in multiple locations across the U.S., our laboratories meet national and international industry standards for quality and are accredited by the likes of the American Association of  State Highway Transportation Officials, the United States Army Corps of Engineers and State Departments of Transportation.
