What Is the ACO K-100 (KlassikDrain K100)?

The ACO K-100 is a general-purpose, modular trench drain system with a 4″ (100 mm) internal width, built from durable polymer concrete bodies and either galvanized (K100) or stainless (KS100) steel edge rails. It’s designed for applications ranging from pedestrian plazas to commercial vehicle areas, with boltless grate locking (DrainLok® or QuickLok®) and a built-in continuous slope option of up to 130 ft (40 m) for efficient runoff management. :contentReference[oaicite:0]{index=0}

Grate choices span plastic, steel, stainless steel, and ductile iron, with styles like slotted, perforated, longitudinal, mesh, and decorative patterns. Load classes cover pedestrian to heavy duty (A through E, per EN 1433 equivalencies noted in ACO literature), with ADA, heel-resistant, bicycle-safe, and anti-slip options available. :contentReference[oaicite:1]{index=1}

Key Features & Benefits

  • 4″ internal width; ~5.12″ overall width footprint for compact installs. :contentReference[oaicite:2]{index=2}

  • Edge rails: K100 (galvanized) or KS100 (stainless) for durability/aesthetics. :contentReference[oaicite:4]{index=4}
  • DrainLok® / QuickLok® boltless locking—fast grate access and reduced maintenance time. :contentReference[oaicite:5]{index=5}
  • 0.5% sloped channels with numbered sections for continuous grade and easy layout. :contentReference[oaicite:6]{index=6}
  • Broad grate portfolio (ADA, heel-resistant, bicycle-safe, anti-slip, decorative). :contentReference[oaicite:7]{index=7}
  • Installation drawings for asphalt, concrete, and pavers; load classes A–C commonly detailed. :contentReference[oaicite:8]{index=8}
K100 trench drain grates—slotted, perforated, longitudinal, ductile iron
Wide grate selection: plastic, steel, stainless, and ductile iron; ADA and heel-resistant options.

Grate Options & Load Classes

Choose grates by load class, material, slot pattern, and locking type. For example, stainless longitudinal grates meet ADA and heel-resistant needs in light-duty areas, while ductile iron slotted grates cover heavier traffic. ACO’s cataloged options list intake areas and part numbers for quick hydraulic checks. :contentReference[oaicite:9]{index=9}

Grate Style Typical Material Locking Common Use
Perforated Steel / Stainless DrainLok® Pedestrian areas (Class A)
Slotted Plastic / Steel / Iron DrainLok® or QuickLok® Light to heavy duty (A–E)
Longitudinal (ADA/heel-resistant) Plastic / Steel / Stainless / Iron DrainLok® Public plazas, entries
Mesh / Decorative Steel / Iron DrainLok® / QuickLok® High intake or architectural accents

Where the K-100 Works Best

The K100 is widely used in car parks, plazas, education campuses, athletic venues, shopping centers, dealerships, and more. ACO’s portfolio shows installs at locations like Sun Devil Stadium, Dodger Stadium, and the American Veterans Disabled for Life Memorial—evidence of its versatility in real projects. :contentReference[oaicite:10]{index=10}

  • Pedestrian plazas & sidewalks — ADA-friendly grate choices.
  • Parking lots & drive lanes — light to heavy duty grates (A–E).
  • Retail & mixed-use — decorative grate patterns for aesthetics.
  • Sports & recreation — continuous slope improves runoff capture.

Sizing, Materials & Performance

Channel bodies are polyester polymer concrete with excellent mechanical properties and low absorption for freeze-thaw and chemical durability. Typical published values include ~14,000 psi compressive and ~4,000 psi flexural strength, with ~0.07% water absorption. The nominal clear opening is 4″ with an overall width around 5.12″. :contentReference[oaicite:11]{index=11}

The K100 series supports DrainLok® (integral) and QuickLok® (spring-bar) locking, and offers constant-depth and sloped channels that are system numbered for layout accuracy. Continuous slopes up to 130 ft (40 m) are documented across the KlassikDrain range. :contentReference[oaicite:12]{index=12}

Installation Overview (Concrete, Asphalt, or Pavers)

  1. Plan the run & elevations: confirm start/end invert levels; select sloped vs. constant depth; verify grate class.
  2. Base prep & form: excavate; compact subgrade; set rebar/forms per the chosen pavement section.
  3. Set channels: follow numbered sequence; connect end profiles; seal joints if watertightness is required.
  4. Concrete/paver/asphalt placement: respect haunch details and expansion joints; maintain edge rail elevation.
  5. Fit grates & lock: use DrainLok® or QuickLok®; confirm security and ADA/heel resistance as specified.

ACO provides downloadable installation drawings for multiple pavements and classes (A–C) to match your substrate and loading. :contentReference[oaicite:13]{index=13}

ACO K-100 FAQs

What’s the difference between K100 and KS100?

K100 uses a galvanized steel edge rail; KS100 uses a stainless steel edge rail for corrosion resistance and enhanced appearance. :contentReference[oaicite:15]{index=15}

Which grate should I pick?

Match load class to traffic (A–E), then pick material (plastic, steel, stainless, ductile iron), pattern (slotted, perforated, longitudinal, mesh/decorative), and locking (DrainLok®/QuickLok®) based on ADA, heel-resistant, bicycle-safe, and anti-slip needs. :contentReference[oaicite:16]{index=16}

Is the channel durable in freeze-thaw or salty environments?

Yes—polymer concrete has high strength and low absorption, and ACO documents frost, salt, and chemical resistance in K100 spec data. :contentReference[oaicite:17]{index=17}

Are installation details available for different pavements?

Yes—ACO provides drawings for asphalt, concrete, and paver installs across load classes (A–C). :contentReference[oaicite:18]{index=18}
