Hi The front gate to my property needs replacing as does the posts. The are an odd size (old / 4 3/4"). The are set in the path on the main road so can't really break it up and reset it.
So can I remove existing post by drilling out etc then setting a 100x100mm post in the exist hole (with shims to hold) and backfill with wet concrete? I can't think what else to do!
thanks in advance
