Upstone Materials is a brand that has been in operation since 1948. Formerly known as Graymont, the company was founded by Ronald Graham and his brothers. Upstone Materials specializes in the production and supply of aggregates, asphalt, and ready-mix concrete.

With their numerous locations throughout northeast New York, they are the dominant supplier in several counties. The company has a strong commitment to safety, and their acquisition by Barrett Industries in 2017 further enhanced their safety policies and procedures. Upstone Materials prides itself on being a material supplier within its geographic footprint, rather than performing construction work.

This affiliation with Barrett Industries also provides opportunities for career growth within the larger Colas organization. Their high-quality materials are used in various construction projects, including roadways, landfills, retaining walls, bridges, and residential projects. They also cater to the needs of educational institutions, providing materials for the improvement and expansion of their facilities.

As a part of the Barrett/Colas family, Upstone Materials is dedicated to ensuring safe operations and continuous improvement for many years to come
