But I would guess (I'm not a stone mason, not related to one, never been
stoned, etc....) that stone is a lot more solid than sand, portland
cement and gravel that haven't been mixed correctly or cured properly.
But without more details or seeing it, who can say?

But what if the concrete was indeed mixed incorrectly? IMO, it will be
crumbly

for the entire 4' length through the ground. It won't be a solid
supporting mass at all.


You mean like the stone foundations supporting 250 year old houses here in
New England? Not a drop of cement, just packed stone.
