There is probably less force supporting a round pole in a round hole than a
rebar tower base, so I think you would be much safer using the manufacture's
recommendation of concrete. Also, you have a large hole and Polecrete
hardens in minutes, can you mix it and pour it that quickly?

Finally got the hole done today for the HG-52-SS tower going up here. I am
up on the side of a hill and the antenna is to be a two element quad. The
hole is 5 feet deep and is in solid rock. Not shale or scattered rocks,
solid. No dirt whatsoever. It is essentially a five foot hole drilled just
slightly over the diameter of the factory one inch rebar welded base for
the tower. With rock under the tower, it is going nowhere from a
compression point. With the base five feet into solid rock, it cannot ever
tip over.
Has anyone ever used polecrete? I have access to it and it is now used to
set roadside billboards, light poles, telephone/power poles, etc. and I'm
considering that instead of regular concrete because this hole is a stable
as any possibly ever could be. The factory base is almost five feet tall,
is made of one inch rebar that is welded and it touches the sides of the
rock hole at all three sides, already preventing any lateral movement. I
seriously doubt that if I simply repacked the rock dust back and wet it
that the base would ever move. I am looking at the polecrete as a serious
possibility as the fill.
Again, it's a solid rock hole, factory one inch rebar base, and will only
have a quad on it. Any help would be much appreciated.
