It looks like I responded to the wrong message in my previous post.
I would do one of the following:
1. Move over 10' or so and dig a new hole. If you have the room you could
end up with two bases and two towers.
2. Dig out all around the existing base and remove it. Finish resizing the
now larger hole and pour the new base in the now properly sized hole.
I think that fooling around with the existing base is probably possible but
it would require quite a bit of work to do it right. The end result would
probably not be cost-effective. By the time you dig out enough around the
existing base to do any retrofitting right you will already have most of the
digging done (except for total depth) to just pour a new base.

Subject: [TowerTalk] Refitting existing concrete base
Question: Does anyone have knowledge or experience adding concrete to an
existing base to increase the mass and adding new anchor bolts? Bolts
would have to be drilled and epoxied in the resulting base??
I have a substantial base for an existing tower, ~ 2.7 yds of concrete. It's
in use with a guyed 60' GM aluminum tower.
I will replace this tower with a USTower 72' crankup that needs a 5x5x8 ft
cube of concrete with different & more anchor placements.
Current base is 5ft x 5ft x 6" pad on top of a 42"x6' deep cylinder of
concrete. All is tied together with rebar, one pour.
God Bless & 73!
