This 75 x 75mm concrete repair spur is designed to stabilise a wooden fence post that has failed near ground level while the rest of the fence bay remains worth keeping. It is approximately 40 inches long with a 75 x 75mm square section, giving a relatively compact repair support that can be installed beside the existing timber post.
The 75mm spur is the slimmer repair option. It can be appropriate where the post dimensions and fence load do not require the larger 100 x 100mm repair spur, and where minimising the size of the concrete support beside the existing fence is useful. Match the spur to the actual repair rather than assuming both sizes are interchangeable.
Installation involves setting the concrete spur beside the damaged timber post and fastening the two together once the spur is securely fixed. This allows the concrete component to support the weakened area without dismantling an otherwise serviceable panel and rail arrangement. If the timber is badly split well above ground level, loose throughout its length or unable to hold suitable fixings, replacing the post may be more appropriate than reinforcing it.
Concrete is well suited to this repair role because the section at or below ground level will not suffer timber rot. Bolts are not included, so suitable fixings need to be selected separately; the ironmongery range may be useful when planning the hardware required for the repair. Do not rely on a small or corroded fixing to transfer the fence load into the spur.
Before digging, check for services and make sure there is enough room beside the existing post to install the spur without damaging the neighbouring panel or boundary. Where concrete or post mix is needed around the repair support, use an appropriate option from the cement products range. If several posts have failed or the fence structure is broadly deteriorated, compare replacement options in the wooden fence posts range rather than repairing each post individually.
