A neighbour of mine use to brush more sand into the driveway blocks at intervals, he also used weedkiller mixed into the sand to stop weeds growing. If this was not done then weeds would grow, making it necessary more often to weed, then brush in more sand. This idea of his did allow less frequent maintenance of what is a very large driveway.
