Southern Maine's trusted topsoil & aggregate supplier for 84 years.
Three generations of Dubois have been mining, screening, and hauling out of York County since 1942. Today we run our own pit in Lyman and deliver screened loam, crushed stone, gravel, sand, and mulch to homeowners, landscapers, and contractors across southern Maine — clean material, honest loads, on-time trucks.
Aggregate solutions for every need.
Locally mined aggregate for the jobs southern Maine is built on.
From road base and building pads to drainage stone, rip-rap, and structural fill, we produce a complete line of locally-mined aggregate materials. Our crushed stone and gravel are screened to spec for site work, foundations, driveways, and erosion control, and loaded by the ton or by the truckload out of our Lyman pit.
Excellence starts at the pit.
Crushed stone is our backbone. We run our own screening and crushing plant, grade our own aggregate, and load our own trucks.
