How to fix a leaning fence?

Helpneededhere

Hey everyone, thank you in advance for taking the time to read this. I have a fence that has started to lean a bit to the outside, I suspect it is because of the height difference between he ground and the garden, there is about 75cm of height difference between the foot path and the top of the soil). The wooden posts retaining the soil in have started to lean quite a bit as well so might be because of them resulting in weaker foundations for the fence. I want to fix the leaning of the fence so what steps should I take?

Hi @Helpneededhere.

A warm welcome to the Bunnings Workshop community and thank you for your question.

If the soil behind the retaining wall has eroded, which seems like a likely reason for the lean, then the concrete at the base of the post may have shifted which would explain the lean.

You might like to check out @dant's discussion: How to fix leaning Colorbond fence?

The solution in their case was to excavate around the base of the leaning posts, prop them so they were plumb and reconcrete around them.

This seems like the logical solution to your issue.

Allow me to tag @Jewelleryrescue and @TedBear for their thoughts.

Let me know what you think, and if you have further questions, please don't hesitate to ask.

Hi @Helpneededhere

@JacobZ is right the cheapest solution is to excavate around the post and re concrete the leaning post held in the correct upright position. this will require access to both sides of the fence and two bags of cement and aggregate pre mixed.

I suspect the installer didnt dig the full 600mm holes in the first place is why the lean exists now plus on a slope and staggard fence line a 2.4 meter post cannot be in the ground deep enough. On A slope the longer 3m colorbond posts should be used. Plus I dont see any cement top at ground level (as per installation guidelines ) so the posts not have cement to allow a shorter ground insertion.

Note to all readers Quick set cement is great for fast repairs but has been known to fail in later years don't use it where high strength needed.

A second method is to buy a third colorbond post $16 3M meter long and dig on your side of the fence and insert it into the ground 600mm (for a minimum)

A real cheap way is to put in a star peg into the ground( likes a tent peg holding a tent upright )and tie a rope to the fence top and pull it upright then hammer in a timber wedge in behind the colour bond post until it is upright will an additional 5 % lean (to allow for the post to slump a little after releasing the rope) The dirt and water will eventually fill in behind the post holding it upright.

Hope this helps
