Blair:
Instead of the weatherhead (expensive), you can use two pieces of PVC
elbow joined together to make a 180 degree turn at the top of the conduit.
You'll need a straight joint to connect the two together. Pull the coax
through and downward, then plug up the hole with fiberglass (fibreglass in
VE-land) insulation.

The electrical device you are referring to is called a "weatherhead".

Thank to everyone who replied to my query. You have asuaged my fears and
will proceed with embedding my feedline conduit in the tower foundation. I
will likely cap the schedule 80 conduit with a termination similar to that
which is used for overhead electrical utility lines feeding a meter base. I
can't recall the actual name for this cap at the moment, but you get the
idea.
Regards, Blair.

Good afternoon, All.
I have not found a satisfactory answer to whether or not a 2 or 3" schedule
40 PVC conduit, installed ~3' below grade and into a 5' x 5' x 4' deep
steel-reinforced free standing tower foundation will derate or harm the
slab's overall integrity. I am preparing for my new tower (to be installed
next spring) and would like to bring the cable feeds up inside the tower
base thereby eliminating tripping hazards and other aesthetic concerns.
Thanks in advance,
