I need to install a small privacy fence for my wife. I want to put in 4 4x4 posts so I can attach a short privacy fence.
I purchased some 10" 6ft concrete tubes, since the ground is very dry-packed. When you dig, it kinda collapses back into the hole. Is it okay to put posts inside of a concrete tube form? Also can I just make the posts only go 2ft down, and 4ft above ground? Additionally, I'm not sure if I should put gravel at the bottom of the concrete, or just straight poor it. I'm in SoCal, and we have very dry dirt. Once you break it up, it doesn't stay compacted unless it gets wet, then it turns into mud. So I figured I'd need those tubes to keep things from collapsing inward. Also I was told to use high strength concrete, but those are 60lb bags and they're crazy heavy. Can I get away with 50lb bags? If I get quick-set, does that mean I have minutes to work? submitted by /u/compubomb [link] [comments]
