I am replacing some Rohn 25 with 45 and find that the concrete pad isn't
quite level. The old 25 plate seemed just fine, but the new 45 plate
definitely has a gap on one side of about a quarter inch when I get the
first section level with the temporary 1/4" EHS guys.
I have ordered the smallest amount of non-shrink grout (quikrete) I
could find, which was 20 pounds. I'm sure that will be more than enough!
Here's my question. I am going to get the first 30 feet of tower
installed with a permanent set of guy wires. Is this the time when I
should apply the grout? If so, do I just keep shoving the grout in from
the sides until I've filled in the gap as well as I can? I suppose a
thin wood or metal strip could be used to really shove it in there
tightly. I guess the idea is to distribute the downward pressure of the
plate as evenly as possible and avoid any undue stress on the plate itself.
Once the grout is in there, it seems to me that there won't be any way
for the drain holes to function properly, so I assume I need to drill a
small weep hole in each of the legs as close to the base as I can get. I
was thinking maybe an 1/8 of an inch diameter would be plenty since the
tops of each leg are covered and the only water accumulation would be
from condensation.
Thanks in advance for your advice.
