Installation
The information on this page should be considered as general advice only.
ACO offers this guidance in good faith and if in doubt, engineering advice should be sought.
Typical installation drawings
- Prepare a trench 200mm wide by 200mm deep. Fix a line along the trench at required finished height. Lay a bed of good quality concrete in the trench.
- Knock out the preformed outlet in the base of the channel or sump unit or fit a spigot stop end.
- Position outlet channel or sump unit in the concrete bed and ensure it is level. Connect to the drain or soakaway.
- Lay the remaining channels starting at the water outlet point. Hold each channel horizontally when lowering into the interlocking joint. Fit end caps.
- Position grates and surround channels with concrete haunching. Paving bricks should be laid in a bed of mortar.
- Ensure the finished paving is 2-3 mm higher than the grates to assist drainage into the channel.
If required, ACO strongly recommends wet cutting, wet drilling and/or wet grinding of polymer concrete products in a well ventilated area with the use of personal protective equipment (including masks).
Plastic Sumps
- Excavate a hole to the required depth
- Cut sump with sharp knife or hacksaw to fit drainage pipe
- Position sump on sand bed or mortar.
- Connect the drain pipework to sump
- Backfill and make good surrounding area.
‘Polycrete’ Sumps
-
- Excavate a hole to the required depth.
- For pipe entry or exit, cut a hole of the required diameter in the plastic insert
- Lay the sump on sand bed or concrete if sump will be exposed to vehicular traffic
- Connect drainage pipework to sump and seal joint.
- Backfill and make good surrounding area.If required, ACO strongly recommends wet cutting, wet drilling and/or wet grinding of polymer concrete products in a well ventilated area with the use of personal protective equipment (including masks).
1. Excavate area to accommodate trench drain and 100 mm concrete surround.
2. Rough in 75 mm or 100 mm outlet pipe, compact excavation base and lay 100 mm deep concrete bed.
3. Knockout channel base for outlet.
4. Lay channels working away from outlet, channels slide-fit together.
5. Pour 100 mm concrete around channel sides allowing for pavement detail.
6. Finish pavement, pavers must be 3 mm higher than the grate.
For pedestrian only applications, trench drain can be set directly on well compacted soil. For driveway applications, trench drain MUST be surrounded 100 mm of concrete.
1. Excavate area to accommodate trench drain and 100 mm concrete surround.
2. Pour concrete bed 300 mm wide by 100 mm deep; keep outlet pipe clean.
3. Lay channels starting at outlet. Set a string line at required height to ensure level. Seal joints if required.
4. Fit end caps and insert grates. To keep concrete from getting onto grates or seam, protect grates with plastic.
5. Install pavers or finish pavement surround to required level, 3 mm above grate.
6. Clean away debris, remove protective plastic.
For driveway applications, trench drain must be surrounded by 100 mm of concrete.
If required, ACO strongly recommends wet cutting, wet drilling and/or wet grinding of polymer concrete products in a well ventilated area with the use of personal protective equipment (including masks).

Installation devices are used to align channels to create a complete trench run. Once the installation is complete using these devices the concrete is poured around the device and channels. Installation devices allow a single concrete pour.
For 100mm wide channels Part Number - 97477 | For 200mm wide channels Part Number - 97478 | For 300mm wide channels Part Number - 97479 |
On-site fabrications are required whenever a trench is to form a corner or junction. All half metre polymer concrete channels have drill-out details on the side to aid the formation of corners and T junctions but all channels can be cut and fabricated to create the desired layout.
ACO strongly recommends wet cutting, wet drilling and/or wet grinding of polymer concrete products in a well ventilated area with the use of personal protective equipment (including masks).
T junctions
T junctions are when an opening is cut into the side of one channel and another channel is butted up to this opening.
DrainLok – barless and boltless locking system
Compatible with KlassikDrain & SlabDrain Grates.
Fast locking device removes the need for bars and bolts and improves the channels hydraulic capacity. The DrainLok mechanism simply clips into the channel edge rail for quick installation.
ACO’s DrainLok grates are fitted with anti–shunt lugs that restrict grate movement when installed, improving durability and longevity of the system.
QuickLok – boltless locking system
Compatible with KlassikDrain & SlabDrain Grates.
Comprises a spigot fitted onto the grate and a removable QuickLok bar in the channel, the QuickLok system locks the grate to the channel by aligning the spigot over the bar and applying pressure until they ‘snap’ together.
With no loose bolts or bars, QuickLok provides a secure boltless lock that is still easy to remove for maintenance and cleaning. This saves time and money during installation.
PowerLok – barless and boltless locking system
Compatible with PowerDrain & SlabDrain Grates.
Fast locking device removes the need for bars and bolts and improves the channels hydraulic capacity. The PowerLok mechanism simply clips into the channel edge rail for quick installation.
ACO’s ductile iron edge rails have anti–shunt lugs that restrict grate movement improving durability and longevity of the system.
