| The above-ground part of the deck footings, made in sonotube, were not shedding water very well. They were flat or a little concave at the top, so I ground them to a nice curve with a 4" angle grinder and a dry serrated diamond wheel. Does not take long at all, diamond eats up pretty much everything. |
