"shelf basement" or "michigan basement"
i posted this a couple days ago in the foundation forum and only got one response. i thought i would try to post here and see if there was more action.
i recently reviewed a shelf foundation in a residence built in 1900 where part of a foundation wall had collapsed due to flooding.
there were no stones or rock visible in the debris, only earth and the thick cementitious slurry top coat.
does anyone have experience or knowledge of this type of foundation system? also, is a "michigan basement" the same thing?
i found one resource that described a "michigan basement" as a thick wall of rock & gravel retrieved from the basement dig, then covered in a cementitious slurry as a waterproofing measure. i wondered if that was the same as a "shelf basement" and if anyone had additional resources on the construction method.
