30m close board fence

[tomboyse]

I am installing a 30m fence, which will consist of close board at 2x2m with intermediate posts. Please can somebody tell me the approximate size of hole and post mix needed for each post as i'm worried that with the shear lenght of it, it will need to be deep to avoid collapse.

hi, just make sure the posts are in the ground at least 2 foot and keep the hole around 30-40cm across shouldn't be a problem whatever length your fence is or if your using timber or concrete posts.
