Wish I would have heard this suggestion a few years ago. PVC sleeves are a great idea. We used metal pipe for the sleeves, and rust has become an issue.vc said:If you are building from scratch, find PVC pipe that is just large enough that the post will fit in, use the PVC pipe to place sleeves in the concrete so you can remove the post when needed. I preffer the PVC since it won't rust, Sch. 40 or above.
The outfit we get steers from just built one, see below.
