EXCAVATION
Trench excavation must be 4" [102mm] greater than the trench depth and a minimum width of 14" [356mm]. Soft and/or
shifting soil substrates may cause cracking of the concrete and consequent movement of the trench. It is critical that the
concrete be poured on an adequate foundation.

INSTALLATION INSTRUCTIONS
JOINT CONNECTION
Assembling the trench run is easy using Flo-Thru’s mechanical interlocking joints. Simply align the two mating ends of the
trench sections and fasten with the hardware fasteners provided. A silicone caulk, or a construction adhesive, such as Liquid
Nails, is recommended to be used at each joint as a sealer.

INSTALLATION INSTRUCTIONS
POURING THE CONCRETE
It is necessary to install a 4-1/4" [108mm] wide spacer (supplied by others) in the grate section of the trench to maintain the
width during the concrete pour.
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.
Finish troweling should be done to set the top edge of the trench drain about 1/16” [2mm] below the floor grade. Remember to
compensate for concrete shrink that may occur during cure so that the edge of the trench drain does not protrude above the
finished floor grade.

INSTALLATION INSTRUCTIONS
AFTER THE POUR
After the concrete has been poured, vibrated, and given sufficient time to dry, both the grates and grate lock down bolts must
be installed. The center of the grate should straddle the toggle-in lockdown bar. The exception is when the channel is cut. To
place these grates, line up the lock down hole in the grate with the lock down hole in the bar. Grates with a length of under
12” [305] will not be able to be locked down. Lock down bolts can be installed using a 7/16” socket. Insert a thin screwdriver
through the grate to support the right side of the lockdown bar to hold it in the slots while tightening the lockdown bolt.
