My basement floor has buckled up in two different places. It has probably raised about 2"- 3" in an area of about 2sq.feet. I have considered some type of floor leveling compound, but then I would be raising the entire floor level. This buckling was a pre-existing condition when I bought the house 8yrs. ago. The floor has not moved anymore since then. Are there any alternatives? Can I just cut out the high spots with a concrete saw and fill in, or will that effect anything else? Can someone help?
