ACO Trench Drain Systems: Full Product Line Guide | Eastgate Supply
ACO Trench Drain Systems: KlassikDrain, PowerDrain, and the Full Product Line
In This Guide
When engineers, contractors, and facility managers specify drainage channels for driveways, commercial parking areas, warehouses, and landmark public spaces, ACO trench drain systems appear on project after project — across the residential driveway to the AT&T/Cowboys Stadium and the World War II Memorial in Washington D.C. There is a reason for that consistent specification: ACO's combination of polymer concrete body technology, factory-built slope, and integrated grate systems produces a result that cast concrete, plastic, and other alternatives simply cannot match.
This comprehensive guide covers the complete ACO product line available at Eastgate Supply: KlassikDrain K100, K200, and K300, plus PowerDrain S100K. It explains the manufacturer background, the material science behind polymer concrete, the differences between each system, the full range of grate options, load class ratings, and real-world case studies of where ACO drainage systems have been deployed at scale.
About ACO Drain
ACO (full name: ACO Group) is a German-headquartered manufacturer of drainage systems and water management products operating in over 40 countries. Founded in 1946, ACO has spent more than seven decades refining linear drainage technology. Their polymer concrete channel drain systems are used on every inhabited continent in applications ranging from residential driveways to airport aprons to food processing plants to world-famous public spaces.
ACO's contribution to linear drainage technology includes several key innovations that are now considered standard features in the industry:
- Polymer concrete body: ACO was among the first manufacturers to move from cast concrete to polymer-bound concrete for channel drain bodies, producing a denser, less porous, more chemically resistant material.
- Factory-built continuous slope: The internal 0.5% slope cast into ACO channel sections eliminates the need for graded excavation in most applications — one of the biggest labor-saving innovations in channel drain installation.
- Boltless grate locking: DrainLok, QuickLok, and PowerLok systems secure grates without fasteners, making grate removal and replacement tool-free while preventing grate displacement and theft.
- Modular assembly system: Standardized 1-meter channel sections with anti-shunt lugs and numbered alignment features allow any run length to be assembled with precision from stock components.
The Polymer Concrete Advantage
All ACO KlassikDrain and PowerDrain systems are manufactured from polymer concrete — a composite material that replaces the Portland cement binder of ordinary concrete with a polymer resin (typically polyester-based) combined with high-density mineral aggregates.
The practical results of this material choice:
- Non-porous: Water absorption below 1% versus 5–10% for ordinary concrete. No water ingress means no freeze-thaw damage.
- Chemical resistance: Resists acids, alkalis, fuels, oils, road salt, and most industrial cleaning chemicals. Ordinary concrete is attacked by all of these.
- High compressive strength: 10,000–18,000 psi versus 3,000–5,000 psi for ordinary structural concrete.
- Smooth surface: Factory-cast polymer concrete surfaces are smooth and non-porous, enabling self-cleaning flow and meeting hygienic drainage standards in food service environments.
- Dimensional precision: Factory molding produces consistent cross-sections and precisely built-in slopes, which field-formed concrete cannot replicate.
- Long service life: Without the deterioration mechanisms (freeze-thaw, chemical absorption, erosion) that limit cast concrete, ACO polymer concrete channels maintain their structural and hydraulic performance for decades.
KlassikDrain K100 (4")
ACO K100 / KS100 KlassikDrain
Width: 4 inches (100mm) • Load Classes: A–D • Grate Lock: DrainLok
The K100 is ACO's most widely installed residential and light commercial channel drain. At just 4 inches wide, it fits neatly across driveway aprons, along patio edges, at garage thresholds, and in landscape applications without requiring significant concrete cutting or disruption. The compact footprint makes it the default choice for any application where drainage capacity requirements are met by a 4-inch system.
Key features: polymer concrete body, built-in 0.5% slope for runs to 130 ft, DrainLok boltless grate locking, anti-shunt lugs, numbered modules for alignment, galvanized/stainless/ductile iron/plastic grate options.

KlassikDrain K200 (8")
ACO K200 / KS200 KlassikDrain
Width: 8 inches (200mm) • Load Classes: A–E • Grate Lock: QuickLok
The K200 doubles the hydraulic capacity of the K100, making it the standard specification for wider driveways, commercial parking areas, high-rainfall environments, and sites where a larger drainage area must be served by a single channel run. The 8-inch width also provides more structural mass in the surrounding slab, making it more appropriate for applications at the upper end of the K100's load range.
Key features: same polymer concrete body as K100, QuickLok boltless grate system, built-in 0.5% slope for up to 130 ft, stainless and galvanized edge rail options, full grate material selection.
View ACO K200 KlassikDrain at Eastgate Supply →Best applications: Wide driveways, commercial parking lots, car wash bays, loading zones, high-rainfall residential sites, commercial kitchen drainage, exterior industrial drainage.
KlassikDrain K300 (12")
ACO K300 / KS300 KlassikDrain
Width: 12 inches (300mm) • Load Classes: A–E • Grate Lock: QuickLok
The K300 is ACO's highest-capacity KlassikDrain system. At 12 inches wide, it handles the hydraulic demands of large parking areas, shopping center access roads, industrial site drainage, and any application where the drainage area is large enough to require substantial channel capacity. The same polymer concrete body and factory-built slope technology as K100 and K200 scale to the K300's larger form factor.
View ACO K300 KlassikDrain at Eastgate Supply →Best applications: Large parking areas, shopping center access drives, loading docks, industrial facilities, detention area overflow channels, commercial site perimeter drainage.
PowerDrain S100K (Heavy Duty)
ACO PowerDrain S100K
Width: 4 inches (100mm) • Load Class: Up to F (202,320 lb) • Grate Lock: PowerLok
PowerDrain S100K is ACO's heavy-duty industrial channel drain, engineered specifically for applications where standard KlassikDrain load ratings are not sufficient. The reinforced polymer concrete body and PowerLok grate locking system handle forklift crossings, heavy truck axle loads, aircraft ground equipment, and other extreme dynamic loads without grate displacement or channel failure.
PowerDrain features the same built-in slope and modular assembly system as KlassikDrain but with a reinforced structural profile designed to meet Class F loading. PowerLok provides a more robust grate retention mechanism than DrainLok or QuickLok, critical in environments where grate displacement creates immediate safety and operational hazards.

Grate Options Explained
ACO grates are available in four materials, each suited to different environmental conditions and aesthetic requirements:
Galvanized Steel
Cost-effective standard option. Zinc coating provides rust protection under normal conditions. Appropriate for most residential and commercial driveways, parking areas, and general exterior use. Surface oxidation may occur over time but structural performance is maintained.
Stainless Steel
Best choice for corrosive environments: pool decks, coastal properties, car washes, food service, and chemical environments. Significantly higher corrosion resistance than galvanized. Clean, architectural appearance. Higher initial cost is offset by longer life in harsh conditions.
Ductile Iron
Maximum structural strength for the highest load class applications. Standard material for Class D, E, and F grate specifications. Used in parking structures, heavy truck areas, and industrial sites. Gray finish; typically painted or coated for aesthetic applications.
Plastic
Lightweight and corrosion-proof for pedestrian-only areas. Not suitable for vehicle crossings. Used in landscape drainage, residential pools, and areas where appearance and light weight are priorities over load capacity.
In addition to material, ACO grates are available in multiple slot patterns and bar spacings to balance hydraulic capacity (more open area = more flow) against debris exclusion and safety requirements.
Load Classes
ACO trench drain grates are load-rated per EN 1433. Understanding load classes prevents undersizing the grate for the expected traffic:
| Class | Maximum Load | Application | ACO System |
|---|---|---|---|
| Class A | 3,372 lb | Pedestrian/bicycle, walkways, patios, pool decks | K100, K200, K300 |
| Class B | 28,100 lb | Passenger cars, residential driveways | K100, K200, K300 |
| Class C | 56,200 lb | Delivery trucks, light commercial | K100, K200, K300 |
| Class D | 89,920 lb | Heavy trucks, commercial vehicles | K100, K200, K300 |
| Class E | 134,800 lb | Heavy commercial, highways | K200, K300 |
| Class F | 202,320 lb | Forklifts, aircraft, heavy industrial | PowerDrain S100K |
Important: Load class ratings apply to the grate, not the channel body. Always verify both channel body and grate load capacity for your application. PowerDrain's reinforced body is designed specifically for Class F loads — standard KlassikDrain bodies should not be used with Class F grating.
Real-World ACO Installations
AT&T Stadium (Cowboys Stadium) — Arlington, TX
The AT&T Stadium, home of the Dallas Cowboys, incorporates ACO channel drain systems in its high-traffic exterior plazas and approach areas. Stadium drainage must handle extreme event-day pedestrian loads, vehicle access, and periodic intense rainfall while maintaining a clean, level surface appearance. ACO KlassikDrain's flush-mounted grates and polymer concrete durability made it the specification choice.
World War II Memorial — Washington, D.C.
The National World War II Memorial on the National Mall uses ACO drainage systems integrated into the memorial's hardscape. In a landmark public space where aesthetics, durability, and zero-maintenance performance are non-negotiable, ACO polymer concrete channels with stainless steel grating provide decades of reliable drainage without surface deterioration or maintenance disruption.
Boston Children's Museum — Boston, MA
The Boston Children's Museum renovation incorporated ACO drainage systems in exterior and interior applications. The museum's combination of high pedestrian traffic, public accessibility requirements, and New England freeze-thaw conditions made polymer concrete the necessary material choice. ACO's non-porous body performs without seasonal deterioration.
Hollywood Walk of Fame — Hollywood, CA
One of the world's most photographed urban streetscapes incorporates ACO drainage systems as part of its paving and drainage infrastructure. The visible integration of drainage into a landmark pedestrian environment demonstrates ACO's ability to meet both functional and aesthetic requirements at the highest profile.

Frequently Asked Questions
What makes ACO trench drains different from other channel drain brands?
ACO differentiates on three core features: polymer concrete body (denser, less porous, and more durable than plastic or ordinary concrete), factory-built continuous slope (0.5% for up to 130 ft without additional excavation), and the boltless locking grate system (DrainLok/QuickLok/PowerLok) that eliminates grate lifting and displacement without tools. ACO systems are also installed at globally recognized landmark projects including the AT&T/Cowboys Stadium, World War II Memorial, Boston Children's Museum, and Hollywood Walk of Fame.
What is the ACO KlassikDrain system?
ACO KlassikDrain is ACO's flagship general-purpose polymer concrete trench drain system. It is available in 4-inch (K100), 8-inch (K200), and 12-inch (K300) widths. Each size features a polymer concrete body with built-in 0.5% slope, anti-shunt alignment lugs, numbered modules, and a boltless grate locking system. KlassikDrain is suitable for residential driveways, commercial parking areas, patios, industrial floors, and most standard drainage applications.
What is the ACO PowerDrain S100K?
ACO PowerDrain S100K is a heavy-duty trench drain system with a reinforced polymer concrete body and PowerLok grate locking system. It is rated to load class F (202,320 lb) and is designed for applications where forklifts, heavy trucks, or industrial equipment cross the drain. PowerDrain is the appropriate choice for warehouses, distribution centers, manufacturing floors, and aircraft maintenance facilities.
What is the difference between ACO K100, K200, and K300?
The K100, K200, and K300 designations refer to channel width: K100 is 4 inches wide, K200 is 8 inches wide, and K300 is 12 inches wide. All three use the same polymer concrete body material and share the factory-built 0.5% slope feature. The wider channels handle greater flow volumes and are appropriate for larger drainage areas. Channel width selection depends on drainage area, rainfall intensity, and the number of outlets.
