As different terms are used in different parts of the country, I have to 
ask, what's a "stem wall". I wonder if that's the same thing we call a 
"rat wall".  It's more or less and extension of the floor slab about 16 
or 18" deep without an actual foundation.

There are two ways in. Through the outside wall or the foundation.  I 
have a full basement under the house and the shop is on a slab.  
Although I originally brought the conduit in through the basement wall, 
when we redid the weep tile and basement walls I changed to run the 
conduit up to a NEMA box on the outside of the wall.  The bulkhead 
grounding plate is in the steel NEMA box with a 4" conduit going through 
the end plate for the floor joists. I could have as easily mounted the 
box higher and went directly through the wall, but this way is neater.  
In the shop the conduit come up the wall and then through about 3' above 
the floor.

The conduit can be laid and the concrete poured over it, but that means 
a permanent location for the conduit.

http://www.rogerhalstead.com/ham_files/cablebox.htm shows the original 
runs and the present incarnation of getting the cables to the tower from 
both the house and shop including some of the installation details..

I'm not so sure about being able to offer wisdom. <:-))

73 and good luck,

Also, there are alot of critters and I want to make sure that we don't have any uninvited guests.   My XYL isn't all that fussy but I want to take the opportunity to do a nice clean professional job.
