Reply to comment by --Ty-- in Securing wall to basement concrete floor by S7onez

Ya I figured so which is why I didn’t want to nail/anchor it.

I was told 2” from the the builder and that the 2 post in the middle of the floor that support a beam have thicker footings underneath

It wouldn't be part of the foundation then. So there is a big difference between floors and foundations. Foundations carry the load of the structure. If you just have a 2 inch slab and it's not connected to the walls it's not part of the foundation. You'd best go down to the planning office and get your blueprints and then go to whoever approves building permits and ask them what steps you need to do to follow code. This isn't something you want to wing or guess at.

I could be wrong on this, but I don't think a 2" foundation can legally exist. Especially not in an occupied space.

What do you usually pour or are you use to seeing?

I think typically 4" or more

Yeah. Even for small structures like a garden shed, or a slab for a barbeque, it's always 4" min, and for an actual home, it's 6" min.

There are foundations that don't need a thick pour, like a raft foundation, where the actual footings can be 10" thick, but then the rest of the area is covered in just one or two inches, basically just to keep the dust and dirt down, but those types of foundations wouldn't be used for a basement that's meant to be occupied. At most, it would just be a crawlspace.
