Construction Materials Testing

Our team of certified technicians provide testing of soils, concrete, aggregate, asphalt, and masonry. We perform laboratory testing in support of field testing, including Proctor, gradation, specific gravity, moisture content, organic content, pH value, shrinkage and crumb dispersion, and making and breaking of concrete test cylinders. Our laboratory is certified by AASHTO R-18 AMRL and CCRL, and all testing is performed per the current ASTM or AASHTO procedures. Our team of professionals is certified by the American Concrete Institute (ACI), the International Code Council (ICC), the National Institute for Certification of Engineering Technologies (NICET), and the American Welding Society (AWS).
