Concrete floor leveling?
I plan to have someone install an Armstrong engineered floor, glued. The problem is my floor is not level and the 2 installers I've talked to say they do not level the floor but inject an epoxy glue in the hollow areas after the floor is installed. I'm not real keen on drilling holes in my new floor and was wondering if this is a standard practice.
Is it that hard and expensive to level the dips in a concrete floor?
