I have 6 fence posts that have been set in the brick of a retaining wall. The posts are rotten below the brick level.
Any ideas on how to replace the 100 mm posts. I suspect when I take them out it will leave a nice slot about 105mm wide to get new posts in but it will wobble and bit and there is not enough room to get concrete in.
I thought about poring a resin around them but this won't allow draining and they will probably rot quickly. I could use 75 mm posts to give room for some concrete but it won't match the others (although it is at the side of the house and I won't see it so not too bothered). Don't really want to have to rebuild the wall around new posts either.
Unfortunately some of the wall is a little crumbling so a metal post mount on top of the wall might not hold.
Any suggestions please?
