Any suggestions on a product and technique to level out low patches on a basement floor. Two instances - the original floor had some patches. Also, I had the basement waterproofed two years ago and the cement shrank when drying.
Does anyone think that it is okay to sink nails into the new concrete that was poured when the basement waterproofing was done? I was told to put a sole plate on top against the ceiling and wedge the floor sole plate in but not to attach it with any nails or bolts.
