.....I would put some plywood in there if I could, but the rebar cage is set
and there's no way now. I'm not worried about pouring concrete into the
hole with water in there, I know that it will be displaced. I only wondered
if continually pumping it out between now and Monday would lessen the odds
of cave in. Back in Kentucky (where I'm originally from) this would be no
problem in that clay, but here in Florida with the sandy soil it wouldn't
take much to soften it at the bottom and cause a cave in.
