Gents, I am in the middle of planning a large garage conversion to living space. 2/3 of the garage is parking space and 1/3 office space. The 2/3 part is split in half with declining slabs ending in floor drains. Can I use self leveling concrete to bring this section of the floor to level? I'd have to cap the drains but shouldn't be an issue and if this is an option I believe I could do it with a few dozen bags of Quikrete self leveling concrete. Thoughts?
