    A Test You May Not Want to Skip

     · Floor Flatness is a measurement of how close a section of concrete is to planar, or more simply whether the concrete slab has bumps of waves as you move across the slab. Floor Levelness is how close a section of concrete is to its intended slope (usually 0). Think about two different types of roadways.
