Here’s a question for everyone. I’m installing a new T-base for my crank-up US 
Tower so that I can use the raising fixture and stop climbing it when it’s 
retracted. (getting too old for that) and I’ve got the holes prepared and am 
wondering about the anchoring material to use.
I’ve drilled the holes 2.5” in diameter to account for the nuts at the base of 
the anchor bolts, which I’ve had to cut off because I couldn’t go deep enough. 
So now I have 2.5” diameter holes to install 1-1/8” anchor bolts in.

My obvious choices are anchoring epoxy, which is expensive at over $20 per 
tube, Quikrete anchoring cement, and I just discovered something called 
Rockite- for anchoring and patching.  I’m hoping that any of these choices will 
work. I’d like to save a few $$ and use the Quikrete which will be much easier 
to use (mix like concrete and pour into the holes). It has a pull-out strength 
of 14,100 psi  after 24 hours and 21,000 psi after 28 days.

Anyone have experience with any of these products. I’d like to do my pour today 
if possible.

Thanks in advance.
