We need to replace a short section (about 100') of boundary fence using 5 or 6" treated pine posts and I have seen foam used to secure them into the ground.
My questions are:
1. Is expanding foam as good as the makers claim.
2. What sort of space do I need between the post and soil, I have an 8" auger on my post hole digger which would only leave a 1" space, is this enough or would I need more (or 1.5" gap on a 5" post).
3. Would I be better off just using quick set concrete mix.
4. What are the differences between a 5 and 6" post.
I am looking at the fastest but don't want to compromise on strength, normally I would use a contractor but as there are a lot of trees on the boundary he cannot get his tractor in and would have to hire a dingo, my BX2370 will fit in and will save me the dingo hire fee.
This is going to be a wire fence with a sight wire on top, I can wire myself, the corner posts are in good condition and I can use these again.
