Cementing in fence posts

[andyboyo]

Hi all im erecting a 30 metre fence on the weekend so just a few quick questions.

how many bags of cement/sand will i need for 30 posts?

should i get ' all in ' sand and stone bags?

what ratio should i use for the mix?

cheers lads!

30 posts ... Are you drilling for oil

dot use cement and sand, use bags of post mix and hardcore. One bag per post, plus a few extra on top should do you.

Have a look down the list of threads as the topics been done to death recently!

All the fencers I know use a dry mix of 1 bag of all-in ballast for each post making a mix of 1 part cement to 6 parts ballast. Dampen the mix but DON'T get it wet.
You put the post in the hole then shovel in the damp mix and tamp it down with a fence post until it is firm.. When you've got them all level you go round with a hose and wet the mix. It will set overnight.

Don't try using wet concrete as your posts will tilt at all angles.

Postcrete is good, pour it in then add water.
