A repair spur is intended for a wooden post that has failed around ground level while enough sound timber remains above to accept the repair fixings. If the post is badly split higher up, loose throughout its length or unable to hold suitable fixings, replacement may be more appropriate.
A concrete repair spur is most appropriate where a wooden fence post has failed around ground level but the remaining post and surrounding fence are still serviceable.
Our 75 x 75mm Concrete Repair Spur and 100 x 100mm Concrete Repair Spur are installed beside the existing timber post. The remaining sound section of the post is then fastened to the concrete support, allowing the weakened ground-line area to be reinforced without automatically dismantling the whole fence bay.
The condition of the timber above the failed section is therefore important. Our product guidance states that replacement may be more appropriate where the wooden post is badly split well above ground level, loose throughout its length or no longer sound enough to hold the fixings connecting it to the spur.
The same applies where deterioration is no longer an isolated problem. If several posts have failed or the wider fence structure is substantially deteriorated, repeatedly reinforcing individual posts may make less sense than reviewing the wooden fence posts and other components as a complete replacement project.
A repair spur is therefore a targeted repair for a suitable existing post, not a way of making severely deteriorated timber serviceable regardless of its condition. Check how much sound post remains before deciding between reinforcement and replacement.
