Re-Fencing using Concrete Spurs

24 Elm Rd Garden. Repairing end garden Fence on Marianne's side. Gone rotten, but using concrete spurs to reinforce Wood posts. Panels totally gone, posts just about Ok. Reinforcing posts with concrete spurs. Use coach screws to attach spurs to wood post. Need to first break away previous concrete block on side of post to which you attach spur. Re-concrete spurs in. Equipment; breaker, coach screws, socket rachet, concrete spurs, bag of Post-Crete per post (it works !!). Sets hard in 10 mins, so need to support post during this time somehow
