FF and FL Numbers - Floor Flatness and Levelness - Archtoolbox
See more on archtoolbox.comTraditionally, concrete floors were specified to have a deviation of less than 1/8" over 10-feet. This was measured by laying a 10-foot straightedge on the finished floor and measuring the greatest gap below the straightedge. This method worked quite well for decades. However, the method also proves to be unreliable and is …How to Determine if a Concrete Floor is Flat and Level
