Anyone ever install vinyl fence on top of a CMU or masonry wall? I'm thinking 3' of exposed 1/2" rebar on the two opposite interior corners of each post, then fill half way with concrete? This is going to be PITA. I'm stumped on this one. There are 6x6's just sitting on the ground holding up the patio which is just blowing out of the timbers. I have this damn fence to deal with (this is a condominium, so they all look like this). Building a wall in front of the fence would look stupid, without the wall I'm going to see failure with the patio. What do you think of this?
