Stoop with no Foundation Wall
Stoop with no Foundation Wall
(OP)
I'm in the Midwest and we typically detail stoops with foundation walls that are extensions of the building foundation wall. I'm currently working on a project with 1000's of feet of storefront where a door could be inserted anywhere along the storefront. We are trying to figure out a way to have a stoop without the additional 4ft tall foundation wall parallel to the building foundation wall. I will be doweling the stoop slab into the building foundation wall, I'm just worried that will act like a hinge. I've heard that on the east coast they use a detail similar to this with no stoop walls. Anybody have a suggestion?
Thanks!
Thanks!

Have the GC coordinate the joints in the slab placement as information becomes available.
I hope this helps.

1) Shallow frost protected apron slab with edge thickening (non-expansive soli).
2) Thin suspended slab with a grade beam and screw piles out front and void form below (expansive soils).
I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

I also like option 1 suggested by KootK so long as the subgrade is fill not susceptible to frost (verify composition with geotech?). I like the idea of extending the "non-frost fill" down to 4' and beyond the plan extents of thickened edge stoop slab by a few feet (give contractor a min dimension).
