Garage door infill–new foundation or??
Looked at a job where the owner would like me to remove a 9′ garage door and stud in a wall with a door and window. The garage slab and the apron were poured mono, 6″ thick, and are nicely done and without cracks. Of course I could cut out a slice of the existing concrete and trench in a new, proper footing and stemwall. The owner wonders if I could simply build the new wall on top of the apron. The building inspector said he would accept that. The entire load of lumber, siding, and rock for this much work wouldn’t even make my 1/2-ton truck sag.
I’m assuming that I’d pour a 6″ high piece of stemwall on the apron to keep my wood framing and siding that far off the slab. Sound OK? Sound like a disaster? It doesn’t sound quite right to me… a little unorthodox… but it sure would be easy!

Isn't that why they make 4" ceement blocks? (4x6x16)
Dave,

Run a 15# electric hammer with a buffing head over the existing 'crete under the stemwall and paint it with adhesive before you pour, or grout if using CMUs.
FYI a buffing head looks like a meat tenderizer.

Stemwall sounds good to me, but it brings up a question I've been meaning to post anyway....to wit, what's best practice when pouring a cold joint like that for waterproofing the "seam"...anyone want to try their hand at this....
Make the customer happy and do as he asks. Anchor down a beefy P.T. 4x4, bedded in some urethane sealant, and build atop that.
Outta there in a day, check in pocket. Sounds like a deal to me.
Outta there in a day... I wish... it's about a month's work if not more for everything they want.
if its poured mono then there is a footing aready there, just build on top.
