In the antique and reclaimed granite business old curbstones are one of the most widely available and reclaimed materials. It is most often used again as curbstone or as landscape steps.
A very functional and I think a great looking application for reclaimed granite curbing is a pavement.
This photo shows a path along the side of my own house that mixes 1.5 to 3 foot pieces of junior or slope curbing with antique granite cobblestones laid on their side.
The photo below shows a driveway that uses uniform lengths of granite curb in a running bond pattern that runs vertical to the street.
Whatever look or style you find attractive Stone Farm can help you source the right material for your job.
