Tried a new way to set a corner post in heavy clay and it worked way better than I thought
I was putting up a fence in a backyard in Springfield last week, and the soil was that thick, sticky clay that just sucks. I usually dig down the full 36 inches, drop the post in, and pack gravel around it. This time, I saw a video where a guy mixed a bag of quick-set concrete with the clay he dug out, made a slurry, and poured that around the post base before adding his gravel. I figured it was worth a shot. I did it on one corner post, let it set overnight, and came back the next day. That post was rock solid, no wiggle at all, and it saved me from having to haul away a bunch of extra wet clay. The other posts I did the old way already feel a bit looser by comparison. I think the mix really bonds with the native soil and locks things in. Has anyone else tried a trick like this for bad ground?
