Weird foundation walls - Planning to finish basement
Hey all,

We bought our first house and it was build in 1950. I am planing on finishing half of the basement to expand the amount of livable room we have.

Anyhow, the bottoms of the foundation walls in the basement are not square. There is a picture attached so you can see what I mean. There is cinderblock under what seems like a coat of extra concrete.

I want to frame out standard walls for drywall using 2x4s but I don't want to lose space starting the new wall so far from the foundation wall.

Should I dig out the curved concrete at the bottom to make it square?

Or use furring strips on the walls and have the drywall hang down over that bottom portion of the foundation wall?

Thanks in advance for any insight anyone is willing to provide.

That section of concrete could be concealing oil lines or a steam boiler return line. Check to see if there are any pipes in the vicinity before demo.
My 1938 house had the return lines covered just like that.

You will do as you want to do, but I'd leave it be and lose the 3-4"s. Potential for issues once you start disturbing that part of the wall. Sort of the let sleeping dogs lie philosophy.

Possible old wall water leak problem, added weep holes to the bottom of the cider block wall and in the concrete floor right at the base of the walls, then covered with concrete.

You could distrub it and see, or as suggested leave the sleeping dog lie, up to you. Curiousity may kill this cat.
