I'm erecting a new picket/paling fence, it's about 10m long and 1m high.
Question is how big should the post hole be ? I'm going down 50cm ie a
third of overall post length but how much concrete do I need around the 10cm
x 10cm post ?
But then few will agree with me.
We never use concrete for posts. Dig hole, large rock in bottom then
back fill with soil, tamping down as you go and keep throwing in and
wedging in stones also.
Haven't had one fail yet and the posts don't appear to rot as quick.
I agree completely ! Use a hole borer if possible, go down about
70/80 cm for the end posts , pack any spaces with sand, grit, small
May not be as solid as concrete but less likely to snap, and if you
have to replace the posts ,its alot more straightforward.
royall at which net
I put a fence up of 4x4 post to take 5'6" panels. used a post hole borer as
there were rather a lot to put up. got about 1/2 a ton of sand and chippings
in to make concrete to go around the post. Boy was I supprised when I only
needed to mix up one wheel barrow of muck. The post fitted so snug that we
just tamped a bit around the sides or used it to bottom fill a hole where we
got to adventurous with the borer! Well I will know next time!
You are looing to pack the gap between the post and the undisturbed
hard soil. You can do this with almost anything, concrete, stones, the
soil that came out.
I guess the exact choice depends upon the soil type, and what mood you
