Please can someone advise on the correct hole sizes and amount of postcrete to be used for fixing 8' concrete fence posts as I am somewhat confused. Work starts tomorrow (22nd June) so an early response would be appreciated.
My current plan is to use a petrol driven auger to drill 8" round holes to a depth of 21" and to fix the posts using Postcrete. The DIY shop said use one bag per hole but another website indicates that this will only take about 1/2 bag for each hole of these dimensions and my concern is whether this is sufficient. What I don\\\'t really understand is whether its the hole that is supporting the post and the Postcrete is simply filling the gap or vice versa.
Many thanks
