Driveway Guides. Granite Driveways | Durable, Heavy and Very Expensive! Granite driveways, much like slate driveways, are among the most expensive, most luxurious in the world, requiring skilled laborers and heavy machinery to properly construct.
These prices can double for a roadway-quality driveway (geotextile fabric covered with three layers of compacted gravel, each about 3-4 thick), or $450-$1,800 for 12'x25' and $11,000-$60,000 or more for a driveway 12' wide and a quarter-mile long.
