I work for a family-run business that owns three quarries north of the Raleigh/Durham area (Carolina Sunrock LLC). One of these quarries is a traprock quarry (diabase basalt) located in Butner, NC. This particular quarry is the only traprock quarry in the southeast. We also have a granite gneiss quarry in Woodsdale, NC and another granite quarry in Kittrell, NC. I would be happy to accommodate for any orders of our aggregates, including rock dust. For quotes on material, please send your inquiries to my email address: firstname.lastname@example.org. Depending on size, we can send material by mail (UPS, US Mail, etc), truckload, or even railroad...we are rail-served out of Butner, and will be rail-served out of the other two quarries in the coming years.
I look forward to any feedback
