SETTING ELEVATION OF SLAB

elevation around walls .
• Form boards set elevation where
there are no walls .
MAKING WET PADS

pins (A) .
Note: Make sure all wet pad distances
are shorter than the length of board
being used .

ing rows (B) .
3 . Once rows are formed, run screed board off of the
two rows leveling the previously untouched con-
crete (C) in between .

must be slightly higher than wet
pad rows (B) prior to striking off .
