How to feed supply lines through Stem wall?

[bren5270]

Hey all,

Im in the process of setting up the rough-in electrical and plumbing lines for my lofted garage. Just finished the block wall, haven't started the slab yet. Trying to figure out the best way of doing this...

Aside from the obvious drilling a hole through the block and putting a 1/2" larger sleeve in, does anyone have any recommendations for the best way to feed supply lines through a cinder block foundation wall then going UP through a slab?

Are you supposed to just put a 90deg and have it pass through the slab in a corner of the garage after it goes through the stem wall??

I attached a pic, need to feed in in through about that blue highlighted block, then up to the second story some how.
Any recommendations?

IF you want to come up through the slab it's not going to be an easy process. Usually builders put conduit in place before the block wall is placed and before the slab is poured.

The only way I can think of to do it after the fact would be to break out a section of the slab and patch/re-pour.

You don't have your location posted - if you are in an area where you don't have to worry about freezing, I'd be very tempted to avoid going through the stem wall entirely and come up and over.

I assume your electric would run underground outside garage. Direct burial wire into conduit with an LB or elbow with top that removes, than drill wood garage wall. Conduit to breaker box.

If you live in a freeze area and use an outside rise be sure to include a slip joint before
it attaches to the wall.

Oops forgot to mention that I haven't poured the slab yet. Also, I live in NC near the coast but we do get freezes from time to time.

If an underground feed use a 1.5 inch "sweep" 90 degree through the slab with a vertical extension to get the high end above the block level.
Planning it so the breaker box will straight above the pipe will make things easier later.
I came up through the block cells but inside the stick wall to the surface mounted box.

Can you do that? wouldn't it mean the line would go right through the sillplate? I was thinking of doing it but wasn't sure if that was actually allowed.

The blocks are 8 inches thick, split face.
The walls are 2 x 4 stick built.
That gives me a aver 4 inch "shelf" on the top, inside edge, of the block.

You would still have room with 6 inch block.

But I have seen 1.5 pipe through a 2x4 sill plate.
