McNICHOLS® Trench Drain System: Installations Tips
·  Lay channels alongside the excavation prior to placement.
·  Excavate to ensure at least 4 inches of concrete (or amount equal to slab thickness, whichever is greater) around sides and under all channels.
·  Make the proper piping connections on the optional catch basin after it is supported in the excavation and then pour the bedding concrete.
·  Remove all cutouts by predrilling the cutouts, spacing the holes as close as possible, then use a cold chisel to remove the bridges between the holes.
·  Begin the installation at the discharge (deepest) end of each run (i.e. highest numbered channels) and proceed upstream.
·  Set the channel using installation chairs.
·  Caulk the joints with appropriate sealant if corrosive solutions will be carried in the channels.
·  Grates must be in place during concreting (remember to cover the grates first to ease cleanup and ensure easy removal of grates).
·  Be sure to secure the channels to prevent "floating" during concrete placement.
·  Do not utilize the channels as expansion joints and do not groove the concrete next to the channel.
·  Stagger grates across channel joints to aid in channel alignment.
·  For sanitary sewer conditions, the channels may be edge sealed with an appropriate semi-rigid epoxy or polyurethane joint filler. Filler must be installed in such a way as not to leave the edge of the channels unsupported against the traffic.
