Providing Advanced Testing + Forensic Capabilities For Construction Materials

Thorough testing and analysis of construction materials is sometimes needed before, during and after construction to ensure a structure’s integrity and safety. Our accredited and independent Materials Laboratory houses state-of-the-art equipment for standardized and specialty testing as well as applied research. The laboratory provides chemical and physical testing and petrography for aggregates, cement, mortar, concrete and other construction materials.
