Commercial Trench Drain System — ACO K100 (4")

The ACO K100 Commercial Trench Drain System is a reliable, versatile modular drainage solution for general-purpose commercial and industrial applications. With a compact 4-inch internal width and the ability to install a continuous slope up to ~130 ft, K100 efficiently manages runoff while keeping surfaces safe and usable. Choose galvanized steel or stainless steel edge rails for long-term strength and corrosion resistance, and tailor performance with a wide portfolio of mesh, slotted, perforated, and ductile iron grates rated up to Load Class E.

Why Choose the ACO K100?

Key features — plain-language explanations:
  • Continuous slope (to ~130 ft) helps maintain water velocity for reliable surface evacuation across long runs.
  • Durable edge rails in galvanized or stainless steel provide long-lasting strength and clean, straight lines at the surface.
  • Boltless lockingDrainLok and QuickLok®—speeds grate fitting and removal, reducing maintenance time and labor.
  • Anti-shunt lugs & numbered channels keep grates stable under load and ensure accurate alignment, slope, and sequencing.
  • Grates up to Class E (mesh, slotted, perforated, and ductile iron) let you balance hydraulics, slip resistance, appearance, and wheel loads.

Best-Fit Applications

  • Retail streetscapes, courtyards, campuses, and promenades
  • Parking decks, drop-off zones, and perimeter curb-line drainage
  • Auto service bays, light industrial aprons, and distribution entrances
  • Commercial hardscapes using decorative grate patterns

Installation Guide (Step-by-Step)

Use this field-friendly sequence (always verify with project drawings and local code):

  1. Layout & elevations: Map the run, outlets, and low points. If using continuous slope, confirm start/finish elevations to maintain hydraulic grade.
  2. Excavation & base: Excavate for channel depth and encasement. Compact the sub-base and place a stable bedding layer.
  3. Set channels: Start at the outlet; follow numbered channels for correct slope sequence. Check line and grade frequently.
  4. Join & align: Seat joints to keep the internal invert smooth; verify grate seats align along the edge rails.
  5. Concrete backfill: Place evenly on both sides to the specified thickness. Re-check elevation to prevent float or twist.
  6. Grates & locks: Fit grates using DrainLok or QuickLok®. Ensure anti-shunt lugs engage along the run.
  7. Finish surfaces: Bring surrounding pavement flush to the rails. Perform a water test and clean the line of debris.
Specifier Tip: Use stainless edge rails near de-icing salts, coastal exposure, or food-service areas. Reserve higher Load Class grates where vehicle wheel paths cross the drain.

Case Study — Concert Venue Concourse Upgrade

Location: Outdoor concert venue with pre-/post-event pedestrian surges and periodic service-vehicle access.
Problem: During heavy rain, sheet flow created slippery areas and forced concessions to close.
Design Approach: The engineer specified ACO K100 in a continuous slope (~120 ft) toward two outfalls. Perforated stainless grates were used near concessions for a clean look and corrosion resistance, while slotted ductile-iron grates were placed across service lanes. Boltless DrainLok/QuickLok® simplified between-event cleanouts.

Outcome: Surface water cleared faster, slip incidents decreased, and concessions stayed open more consistently. Facilities staff reported quicker grate removal/replacement and appreciated the accurate channel sequencing from numbered modules.

Maintenance Made Simple

  • Quarterly debris checks at inlets/outfalls and low points
  • Confirm anti-shunt engagement and grate seating in wheel paths
  • Power-wash channels as needed to maintain clear flow through the run

Specify the Commercial Trench Drain System with Confidence

With its 4" internal width, continuous slope up to ~130 ft, and broad grate options, the ACO K100 Commercial Trench Drain System adapts to plazas, concourses, parking decks, auto bays, and more. Boltless locking accelerates maintenance, anti-shunt lugs keep grates stable, and numbered channels streamline installation—so your team delivers clean lines and reliable drainage on schedule.
