Trench Drain Installation

The 5 step trench drain install

Perhaps the greatest advantage to Preform Trench Drain’s (PTD) innovative design concept is how it simplifies the trench drain installation process. A complete installation can be achieved following five simple steps:

1. EXCAVATE TRENCH:

   The trench should be dug to desired depth and sewer outlets installed where desired.

2. SET PTD HOUSING INTO TRENCH:

   Bolt the box frames together and suspend in trench at proper grade (see step 3). Bolt on end plates where needed.

3. ACHIEVE PROPER GRADE:

   Use angles provided with your housing to set the box into proper position and to the proper grade. Pour concrete for bottom and sides in one pour – or – pour a rough footer bed first at proper level, then pour both sides using the anchors welded to the outside of the box to achieve proper grade. These concrete anchors also act as a stabilizer for the housing to prevent undesired movement.

4. DRAINAGE PITCH:

   Pour concrete inside the box for drainage pitch.

5. PLACE GRATING/COVER IN PLACE:

   Simply place desired grating or diamond plate cover on to housing and secure with clips.NOTE:

• Where vehicle traffic will pass over Preform Trench Drain, it is necessary to surround this trench drain with 4-6 inches of concrete.
• Preform Trench Drain has no bottom and concrete is used to provide the pitch or slope from the high point in the strip to the low point at the sewer outlet. Outlets should be provided BEFORE any concrete is poured.

Sump units are installed in a like manner using a cutting torch or cold chisel to provide openings for sewer tile outlets or vent lines in the sides of the steel sump stool. After lines are installed, pour the bottom and sides, completing the sump installation.
