Materials Testing & Inspection

​We take pride in being on-site when needed most and in providing timely, concise and accurate reports for field and laboratory materials testing. To ensure material quality and construction procedures comply with project specs and design standards, today's building codes and highway standards call for our on-site inspection and laboratory testing of soils, concrete, asphalt, steel, masonry, and other construction materials.

All of our technicians are certified by state agencies and technical organizations in aggregate, concrete, bituminous, and masonry materials testing. With our high level of experience and training, we're proud to be Michigan's go-to materials testing experts. D&A's in-house lab capabilities include soil gradation/classification; permeability; moisture-density relationship; concrete and asphalt mix-design; asphalt extraction, gradation, and marshall density; concrete compressive and flexural strength; and a full range of testing on masonry materials.
