Maximum thickness of mortar bed joint. | DIYnot Forums

30mm with 6:1 or 3:1 mortar? Soft building sand or sharp sand? I suspect the crushing strength will have something to do with it. There is no such dimension for a single joint - joints are based on an average depth over several courses, and DPC joints are double. You would normally pick a corner up over several courses, not a monster joint.
