Superflat Concrete Floor Specialist Contractor
We have suitable leveling equipment and specialists to construct concrete floors of various flatness to meet the different needs of usage according to ACI and ASTM Standards :
Type of Floor Overall FF/FL Numbers
Moderately Flat 25/20
Very Flat 45/35
Super Flat 60/40
We are also applicator for various floor hardeners, according the needs of owners.
We also have Floor Dipstick to measure the flatness of the floor and producing reports with overall and minimum FF/FL numbers, in accordance to ASTM-1155.
Why Floor Flatness is Important ?
a) To increase warehouse efficiency by allowing the material handling equipment, like folklift, to operate at full speed safely;
b) To increase the warehouse storage efficiency by allowing stock stacking at maximum height;
c) To ensure good safety in the warehouse ! Trucks can hit the racking if floor is not flat; driver can get fatigue easily on uneven floor due to excessive vibration;
d) To production costs by reducing damages to goods due to falling off from material handling equipment;
e) To reduce maintenance costs to the material handling equipment and lower downtime for repair;
f) To provide a good, conducive and aesthetical working environment.
Our team is ready to work all over Indonesia, from Aceh, Sumatera, Jakarta, Jawa, Bali, Kalimantan, Sulawesi to Papua.

Floor Flatness & Levelness Survey, Accurate Floor Profile Measurement by Dipstick, F-numbers, Floor Surface Classifications
The floor profile can be measured & expressed in terms of Flatness Number FF & Levelness Number FL according to ASTM Standards.
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.
