A trench drain is a continuous line of surface drainage that removes liquid from a specific area. It has a continuous inlet along the entire length ensuring maximum liquid capture, typically through a grate. Trench drains allow simple, one-way grading of surfaces to be drained.

• 4” (100 mm)
• 8” (200 mm)
• 12” (300 mm)
• Custom – See ACO Aquaduct

• Polymer concrete
• Fiberglass
• Cement concrete
• Plastic
• Metals

Polymer concrete is a composite material produced by mixing mineral aggregates with a resin binding agent. The finished material has excellent mechanical and thermal properties and offers good corrosion resistance against many chemicals.

• Concrete
• Asphalt
• Pavers

• Galvanized steel
• Stainless steel
• Ductile iron
• Plastic

They are made of metal to give stability to the trench overall and gives protection and durability to the channel body. Wearing-edge rails can be made from:

• Galvanized steel
• Stainless steel
• Ductile iron

A Polymer concrete edge or no edge rail is useful where chemical resistance or non-metal options are preferred (e.g. veterinary kennels or sport running tracks).

Sloped channels encourage the water to evacuate quicker. Sloped channels also have a self-cleansing effect extending the time between inspection/maintenance.

• Non-sloping (ideally used when ground fall is present)
• 0.5%
• 1.0% (FlowDrain)
• Custom – See ACO Aquaduct

• End outlets ranging from 4” to 10”
• Bottom outlets ranging from 1.5” to 8”
• Inline catch basins (blends in with the rest of the trench drain)
• Sump boxes (2×2, 3×3, 4×4)
• Free flow (no end cap)
• Custom – See ACO Aquaduct

• Boltless
  • QuickLok®
  • DrainLok
  • PowerLok®
• Bolted
  • 4-Bolt
• Monolithic
  • Grate is built into the channel (see ACO MonoBloc)

• Legislative compliance such as ADA
• User safety such as heel resistant and bicycle safe
• Aesthetics, because the grate will be the only part of the trench visible
• Slip resistance
• Anticipated vehicular traffic and associated load class

• EN1433 the only standard written specifically for trench drain
• ASME112.6.3
• AASHTO HS20/HS25
• 200,000lb proof load

• Load class A (residential and light pedestrian)
• Load class B (sidewalks and small private parking lots)
• Load class C (parking lots and general commercial areas)
• Load class D (Trafficked sections of roads and highways)
• Load class E (Aircraft hangars, light commercial forklifts)
• Load class F (Heavy industrial, docks, aircraft ramps and aprons)

A general purpose system with galvanized steel or stainless steel edge rails. It is available in 4”, 8” or 12” internal widths. It utilizes QuickLok® & DrainLok to secure the grates. Supports load classes from A to E.

A heavy duty system with ductile iron edge rails. It is available in 4”, 8” or 12” internal widths. It utilizes the PowerLok® system and has a 4-bolt option to secure the grates. Supports load classes from A to F.

Used when depth restrictions are present. It is available in 4”, 8” or 12” internal widths. It utilizes QuickLok®, PowerLok® & DrainLok to secure the grates. Supports load classes from A to F.

Provides an ideal solution to long runs in concrete slabs. The fiberglass channel body with steel frames provides a quick and simple way to create a smooth, corrosion resistant trench drain. Channels available with 8” internal width and grate options support load classes C-F.

• CIP – Boxed out trench formed on-site before concrete pour.
• Modular – Factory produced channel units that connect together to create a trench drain system. They offer consistent quality and are created with advanced shape profiles and built-in slope, providing additional benefits and savings.

While all channel and grate combinations will work with pavers, ACO offers the Brickslot system. Brickslot is a discreet system that blends in with paving joints giving a functional and aesthetic solution.
