Good day... I want to remove the top course of from a long concrete-block garden wall. can anyone suggest the easiest way to do that, so as to end up with a reasonably clean top edge, and with as little work as possible? Unfortunately, the wall was built rather well, with 3:1 or 4:1 mortar and
18" x 18" piers every ten feet or so. I'm imagining (probably fancifully) that there might be some kind of tungsten carbide tipped chainsaw tyoe weapon, or something that would cut all the way along and give a fairly clean cut. I'm guessing that using a bolster and a heavy lump hammer is going to be laborious and disheartening way to attempt it. Standing on the top of the wall knocking the top blocks off, one-by-obe with a sledge hammer was another idea, but it might tend to damage the course below the top one. Has anyone had to tackle this one before? How did you end up doing it?
Many thanks
