A national aggregate network with regional coverage.
A short orientation to help you decide whether a Martin Marietta location is the right call for your project.
Martin Marietta is one of the larger producers of construction aggregates in the United States, operating a network of quarries, sand & gravel pits, and ready-mix and asphalt plants. Its aggregates business supplies crushed stone, sand, and gravel for highway, infrastructure, commercial, and residential construction.
The network's footprint is concentrated across the American South, the Carolinas, Texas, the Mountain West, and the Mid-Atlantic, with additional operations in the Midwest and Great Plains. Hello Gravel lists 163 confirmed Martin Marietta locations across 28 states; coverage in any given metro varies by quarry geology and local demand.
Locations across the network typically stock the standard range of construction aggregates — crushed limestone, decomposed granite, washed and unwashed sand, pea gravel, and recycled aggregate — with material specifications meeting state DOT base, sub-base, and rip-rap grades. Specialty products such as basalt, scoria, and ballast stone appear at quarries where the local geology supports them.
Suppliers on Hello Gravel publish a direct phone number to the location's dispatch line. Pricing is quoted per ton with delivery surcharges varying by ZIP; most quarries and plants prefer to quote over the phone rather than publish public price sheets.
