Since its founding more than 60 years ago, the companies of Maple Grove have evolved from the quintessential small business — a small road construction company— to the tri-state area's premier provider of industrial minerals, construction aggregate materials, asphalt paving materials and services, and liquid asphalt storage. Our priority is not to be the biggest, but to be the most qualified resource in our market. Customers have found it a given to count on our exceptional capacity, our person to person availability, the unerring quality of the aggregate products and construction services we deliver, and the flexibility we exercise in meeting their unique challenges.
