Flatness FF is measurement of waviness or bumpiness of floor, it relates to the rate of change the floor elevation over 300 mm interval. FF is mostly affected by the finishing operation.

Levelness FL is measurement of floor tilt, it relates to general floor slope of 2 points which are 3000 mm apart, which defines the relative conformity of the floor surface to the horizontal plane. FL is mostly affected by the forming and strike-off.

ASTM E-1155 Standard details the test method for determining F-numbers, which consist of Flatness FF & Levelness FL.

Dipstick is an inclinometer that uses highly accurate accelerometers to measure changes in elevation of floor & give rapid interpretation and graphical output of F-numbers calculation. It can carry out high precision measurement, up to 0.025mm in accuracy.

For building owner, consultant, and concrete floor contractor who wish to know the flatness and levelness of their floor, we have Dipstick & operator to measure floor profile accurately in Jakarta & other parts of Indonesia.

We can instantly provide the FF & FL values and floor profiles that show all the “ humps & bumps� in the floor – right on the job site. These F-numbers will inform whether the floor finishing meets the specs, and where the problems are in case the floor doesn’ t meet the specs. In addition, we also will produce the Project Summary Report for the entire test surface, according to ASTM E-1155.
