Installation Guide

Deep Series US Trench Drain Installation Instructions
Important: US Trench Drain should always be installed with the grate attached to the
channel.
Installation is: Easy As 1. Prepare 2. Install 3. Finish
1. Prepare Trench
Dig a trench of at least 7 ¼” deep x 10" wide and place compacted bedding sand or concrete in the
base. Ideally the trench drain should be sloped at a grade of 1% to prevent water pooling along the
length of trench drain. Use a string line to ensure straightness and the correct finish height.
2. Install Channel
Connect US Trench Drain sections together using the easy male to female interlocking system. It is
recommended that you connect 3 lengths of US Trench Drain together with the grates attached before
placing it into the trench. It is also recommended to cover the grates with a masking tape to prevent
backfill falling into the trench or damaging the finish of your grate during the concreting process.
Connect a US Trench Drain End Cap to the highest point of your trench drain.
To change direction of your trench drain, use a US Trench Drain Corner Piece to change the direction
to the left or right, or to use a US Trench Drain Tee piece to change the direction to the left and right.
It is also possible to cut and join US Trench Drain in 8" increments using the US Trench Drain
Convertor piece SKU 83370. The Convertor can also be used to connect male ends of the trench drain
or the male end of a trench drain to a Corner Piece, End Cap or End Multi pipe Adaptor. When using
the convertor piece, it is necessary to trim the locking piece of the connecting rib using a sharp knife.
At the lower end of the trench drain, the trench drain can either be connected by using another end
cap or by using a Deep Series End Multi pipe Adaptor SKU 83355 to connect to 3" & 4” Schedule
40 plain end pipe, 3” & 4” ABS plain end pipe, 4” Triple wall solid or perforated pipe, or 4”
Corrugated solid or perforated pipe.
If you want to connect the pipe to the bottom outlet of the trench drain you can use a Deep Series
Bottom Multi pipe adaptor SKU 83356, by cutting out the inner circle collar of the channel and
installing the pipe adaptor to connect to 3" & 4” Schedule 40 plain end pipe, 3” & 4” ABS plain end
pipe, 4” Triple wall solid or perforated pipe, or 4” Corrugated solid or perforated pipe.
*DO NOT USE PVC GLUE*
3. Finish Installation
US Trench Drain expansion joint SKU 50006 or 50012 should be installed on both sides of the trench
drain along its whole length. Upper edge of the strip should be level with the upper edge of the trench
drain. This allows for the grates to be removed once installed should cleaning be necessary. If
installing in concrete, please cover the grates during the pouring of concrete to avoid damaging your
grates or prevent backfill entering the channel.
Once you are ready to start laying your drain, position the trench drain into the concrete slurry or
compacted sand so that the feet of the trench drain are completely immersed. Our unique design will
prevent the need to stake the trench drain into place, as it will not float.
With the US Trench Drain and grate in place, pour concrete along the outer walls of the trench drain
to a thickness of 2" Lightly compact and finish the concrete slightly above the surface level of the
grate (approximately 1/8"). This will promote runoff from the surrounding areas into the drain.
