Known sources; confirm the quarry and selection for your order.
Ask the supplier about current availability, material range, fabrication and test data for your application. A listing or MSHA status does not establish supply readiness.
The producer directly identifies its private Heltonville quarry as the source of its buff limestone. The Norman contact address is not the quarry origin. ILI lists limestone blocks; MSHA identifies dimension limestone as the quarry’s secondary stone classification.
