Sewer line under the slab or embedded in it? (1950's house, MN)
I'm doing some remodel work in my basement and need to set some tapcons but I want to make sure I don't hit the sewer line. I have a rough idea of what it runs so I can be careful in that area, but I was wondering if anyone knows what the building practices were back in the 1950's. Would the sewer line be pretty well under the slab or would they have just poured right on top of it, encasing it in the slab?
