Garage Slab w/Stemwall

[grissom]

I am considering building a 26x28 garage with a 9' sidewall and 8' high garage doors and I was told that I need a min. of 3" in a stemwall height in order for the garage door to properly work.

The one contractor I spoke with said the stemwall is done first then the slab is poured after, so its not a monolithic pour. Is this the correct way?

Thanks

its all very dependant on your area and weather, need more info

Its at about 2800' elevation in the Sierra Foothills with snow generally in the inches only, temps as low as the 20's during the winter

its easier the pour the stem wall after but it depend on how high the wall

Because of the property slope it be up to appx. 28" above grade

Based on the original post, I believe the limiting factor may actually be the garage door header. If he has a 9' sidewall and presumably a minimum double-2x12 header depending on the door size location and roof load, plus a double top plate, that gets you to 7'9-3/4". 3" stemwall gets you back to a full 8'.

BTW, where are you located Grissom?

Foundation footers first. Foundation (including stem walls) second. Floor slab last.

My exposed stemwalls site about 10" taller than the slab floor. I used 2" of foam insulation on the exposed stemwalls inside to give me a thermal break between the heated slab and the unheated walls. I trimmed them out in 1" pine so I would not have to look at them. They look pretty good.

I thought you said you weren't going to look at them and then you say they look pretty good. MAKE UP YOUR MIND
