lowering basement floor?
I have a 1908 house in Minnesota with a ridiculously bumpy concrete slab in the basement. Some bumps are probably about 3 inches higher than other sections of the floor. The concrete is about 1-2 inches thick, has broken away and exposed dirt in some and some patches apparently were poured at different times. Very scary.
I’d like to rip out the existing surface, lower the 29X29-foot floor by excavation (doing the work myself, if possible), level it all off and pour a new, smooth concrete surface. In short, I’d like turn this dungeon into a finished space with 6-12 inches more head room.
Can I do this without causing any structural problems? Will lowering the floor pose risks to the existing walls or chimney?
Thanks for any advice.
Have you figured out how you're going to remove the concrete and soil out of the basement? Where are you going to dispose of the stuff?
When you install the new floor, make sure to install a water barrier, 3" or more of compacted gravel then 3" or more concrete.
As for disposal, I was thinking of renting a dumpster.
