The F-Number System is the new American Concrete Institute (# 117) and Canadian Standards Association (# A23.1) standard for the specification and measurement of concrete floor flatness and levelness. F-Numbers replace the familiar 1/8th inch in ten feet type specs that had proven unreliable, unmeasureable and unrealistic.
