Just a note on the joints themselves, these are randomly cut generally about a sixteenth to 3/16th of an inch deep.  We cut through the overlay material down into the original substrate.  So each one of these stones are individual pieces, it is not like an icing on the cake, so to speak but they are now fabricated and actually individual pieces in and of themselves, which provides again for better longevity in that you don’t have a big sheet or coating over the concrete but you have these individual stones.
