Hello to everyone on the list!
I just completed my foundation for the installation of a new UST HDX-555 tower
and had a question on the dimensions and/or clearances of the re-bar cage to
the top of the concrete pad that will sit above the grade. My question is that
of how much clearance should I have from the top of the cage to the top of the
concrete pad that will be formed above the grade? My installation has it set
now at approximately 2" and there wasn't a spec on the drawings I received from
UST. The total height of the pad above the ground is approximaely 7.5". I am
worried that when I start pouring the concrete, I don't want the cage to lift
out and "pop" out the top of the pad. I read a few web pages a few months back
about just that type of thing happening and wanted to get further clarification
before pouring the foundation.
Thanks,
73, de Ken, N2SMT
