The concrete floor in my basement is very uneven with hills and valleys. There are no cracks in it whatsoever and the floor is likely original to the house so about 60 years old. My goal is not to make the floor level, however, make it plumb. There are differences of 1-2" in some areas and some pits (maybe the size of a baseball but only an inch or so deep). I do not desire to remove the entire concrete pad, but wondered if there is an economical way to pour a thin pad over top. Self levelling mixes are expensive and most don't allow for over 1/2" difference. I was wondering if portland and sand mix with concrete bonding agent and slow cure time would work for my application. I would appreciate any advice.
