concrete grinding: we have remodeled part of our house. we want to put water proof vinyl planks down. well when we took up the carpet we found parquet flooring. There are 4 areas in the hallway that when the house was leveled (before we owned it) the house leveling company poured the concrete level with the parquet flooring instead of the rest of the concrete. I have been told I must have those areas leveled before the flooring I want is to be put down. I can't find any one in my area, sofar, that is able to do this.
