Setting posts for fencing
Could someone out there tell me how to set fence posts with the soil/cement method where the mixture is tamped repeatedly. I would like to know what the proportion of soil to cement should be and how hard to tamp. I have had a go at this before with a heavy crowbar but it was a lot of work and the post moved anyway later. Does the soil have to be dry orpartially wet? Saw a guy put in a few posts in about an hour, he didn't seem to be exerting himself much and only did what looked like minimal tamping.
Any responses (constructive) are appreciated.
