Failure 
Possible Cause 
Remedial Measure 
Vibrates insufficient 
and as a result the 
concrete floor can’t be 
leveled and smoothed 
in the proper way. 
The centrifugal force is too 
low. 
Increase engine speed. 
There are excessive amounts 
of concrete along the leading 
edge of the board. 
Remove the excessive concrete from the board. 
The chosen width of the board 
is too large 
Work with a smaller board. 
Concrete looks 
“WAVY” as the screed 
board passes over it 
Operator moving too slowly 
Walk backwards at a faster pace. 
Too much vibration for the 
type of concrete 
Reduce engine speed and walk backwards at a 
faster pace. 
Leaving HIGH or 
LOW spots during wet 
screeding. 
Concrete too high or low on 
one side? 
Have workers shape the concrete close as possible 
to grade. Maintain about 1 inch of concrete across 
the front of the board at all times. 
Board digs into wet 
concrete. 
Is board positioned correctly? 
Each end of the board must ride on the same sur- 
face. Either each end of the board rides on forms or 
concrete (wet screed) not both.
