Stucco + concrete wall

[blackswaN]

This might sound a bit insane, but could this work?? The idea is to put up fine mesh, do a scratch coat and a 2" stucco layer, then either
(A) fill the form with 3/8" concrete a few feet at a time, or
(B) pour a lightweight styrofoam mix while leaving space to back-pour 3/8" concrete for columns and bond beams.

All reinforced with rebar and proper cure times. I'd like it to pass code, just wondering if this could be a faster way to build or if its a total no-go.

In theory it might work, but it all depends on what you're planning this for. I wouldn't call it insane, but I would call it unconventional and I would say you might want to check with local laws and regulations, just in case. If it doesn't work or there's a problem or something like that, you might want to go for ICF or shotcrete-on-foam panels, which shouldn't be as big of an issue.

Interesting concept! But passing code might be tricky, especially with structural integrity and fire rating concerns. A structural engineer's input could help you with it

Thanks for the insight! I'm planning this for a backyard retaining wall , mainly for landscaping and durability. Do you think the stucco over concrete method could hold up well long-term in a wetter climate, or would you recommend sticking with ICF or shotcrete? Also, any typical local regulations I should watch out for when trying unconventional methods?
