The Face Company, in conjunction with ACI Committee 117, developed<br \/>\nthe basis for the system through the use of a patented continuous Profileograph machine. For a<br \/>\ntypical random traffic industrial or other similar floor slab there are two F-Numbers used to<br \/>\nevaluate the floor flatness and levelness, FF and FL; respectively. FF (flatness) is most affected by<br \/>\nthe finishing operation. FL (levelness) is most affected by forming and strike-off.
