Thanks for your concern. Except for the top 5", that ground is solid very hard clay. The pier will not move, having already leaned hard on it, it didn't budge. A 6ft high pier will not have a center of gravity 6ft above ground. It would be 3ft, and with the additional weight and footprint of the base you can figure the center is just about where the floor will be. We have no such thing as a frost line, so going deeper was not necessary. The hole is 22" deep, and 18" wide at the bottom. The picture posted is not the final hole. And the tube was set only 3" into the concrete. And that isn't rebar, it's fence post, and very strong, designed to set into the ground, with lots of knobby surface for the concrete to hang onto. This isn't the first concrete post we have done, just the first for a mount pier.
And after all that, should it develop problems, well I guess I'll redo it. But I doubt that will happen.
