Finding Decomposed Granite in the Marietta/Atlanta Area

Locating a reliable source for thoroughly decomposed, well-screened granite can be frustrating when local suppliers don’t carry it—even though the region sits on abundant granite deposits. The most direct route is to contact operating quarries in the area; many produce decomposed granite as a by-product of crushing operations and may sell it in bulk or by the truckload.

Start with these steps:

• Search for “granite quarry” or “stone quarry” plus “Marietta GA” or “Cobb County GA.”
• Call the quarry office and ask specifically for “decomposed granite fines” or “granite screenings” that have been screened to ¼-inch minus or finer.
• Request a sample or visit the stockpile to verify the material is well-weathered, not just fresh crusher fines.
• Inquire about delivery options; most quarries load dump trucks directly.

If quarry minimums are too large for your project, check with landscape supply yards that source from local quarries—they often re-screen and bag the material for smaller orders. Online marketplaces (Craigslist, Facebook Marketplace) sometimes list local haulers with smaller loads.

Because you’re “sitting on mountains of it,” a nearby quarry is almost certainly your most cost-effective and consistent source.
