I was wondering, on what intervals, do you guys put a seam in your mortared flagstone patios and mortared walls. Concrete always get joints put in every 10-15 feet. Do you seam you concrete base at all and what do you do on the flagstone if anything. On the walls, I see others seam them with a rubber 'caulk' about every 20'.
