INSTALLATION INSTRUCTIONS
Z886 Concrete
Pour and Finish
Pour the concrete around the three sides of the trench
drain. Be certain to adequately
vibrate
the concrete as
it is being placed. Proper vibration will eliminate any
unwanted voids within the concrete pour. If sidewalls
are used, a first and second pour are recommended.
Verify layout is correct prior to pouring concrete.
PLACING CONCRETE
• Adhere to check that the trench drain is in the
location required per the layout drawings prior to
pouring concrete.
• Standard concrete practices with expansion and
crack induction joints shall be followed based upon
local codes and standards.
• The trench drain shall not be used as an
expansion joint.
Finish troweling should be done to set the top edge of the
trench drain 1/8" [3] below the floor grade. Remember to
compensate for the concrete shrink that may occur during
cure so that the edge of the trench drain does not protrude
above the finished floor grade.
The use of nominal 1x6 (3/4" x 5-1/2") [20 x 140] lumber supplied by
others may be used to keep channel clear during the concrete pour.
Remove shipping/installation
bars as you finish troweling
5.5" [140]
