1997
Diamond Materials, LLC. was founded in 1997 in Wilmington, DE as a heavy highway and site development company. The company purchased by the Pierson’s in early 2000 spent the next decade with the goal of becoming a more vertically integrated company and quickly earned the reputation as one of the premiere heavy highway and site development contractors in the tri-state area. Based on a culture instilled by the Pierson family of a strong work ethic and integrity, our work environment has thrived and empowered all employees to excel with opportunities for growth and development.
Our culture coupled with our unwavering attention to safety, quality and detail, with the use of leading-edge technology and sophisticated machinery, gives us a unique ability to provide our customers with superior end results.
