FLOOR LEVELING PROCESS

ROOF AND SIDE PROTECTION ARE INSTALLED

• Photo 1: Roof and side protection installed for protection from direct sunlight, rain,

and wind getting into the concrete floor during casting This will prevent rapid

evaporation of water from the concrete surface

• Photo 2: If walls are not in place, erect scaffolding cover (blue sheet) locked down

and at least 2 meters high to prevent rain water and wind blowing in during finishing

process

SET UP OF S485

1.) Obtain finish floor level by setting laser guided transmitter

2.) Transmitter will transfer the designed elevation

3.) Laser Receiver are set to the s485 for rough (quick pass) and screeding (smooth)

SET UP OF LASER TRANSMITTER FOR S485

1.) Obtain finish floor level by setting laser guided transmitter

2.) Transmitter will transfer the designed elevation

SET UP GRADE ROD

1 Set Grade Rod to bench mark

2 Read numbers on grade rod

3 Set matching numbers on machine receive poles

4 Screed test pass and adjust

SET UP PUMP LINES WITH LINE PUMP

VIBRATION

Vibrator must be inserted immediately after placing

Vibrator must be inserted vertically to reduce the air entrance

MANUAL ROUGH LEVELING JUST ABOVE GRADE

ROUGH LEVELING BY ‘QUICK PASS’ FUNCTION

The s485 can pull the concrete to a rough level through a function called

“Quick Pass”

FINE LEVEL TO DESIRED FFL

USE GRADE ROD TO CHECK LEVEL

FINE LEVEL OF SCREEDED CONCRETE

1. After first pass of fine level, s485 will move parallel to the first pass

area

HAND SCREED TOOLS FOR EDGING

HAND TOOLS-MESH ROLLER

Mesh Roller is to embed steel fibers and to bring up some cement paste up to surface to cover.Mesh Roller can also be used to push down coarse aggregates at the surface of concrete

HAND TOOLS-CHANNEL FLOAT

After Mesh Roller has pass through, apply channel float to fill surface and improve flatness.Overlap each pass by 50%

HAND TOOLS-CHECK ROD

For higher tolerance floor apply check rod when concrete is still plastic

Overlap each pass by 50%
