About the K100 System

In simple terms: The K100 trench drain system captures surface runoff and directs it away from traffic zones, walkways, and buildings. Each 39.37″ modular section connects seamlessly, making it suitable for projects of any size.

Applications:

  • Urban streets: Handles stormwater in high-traffic areas.
  • Parking facilities: Prevents puddles in lots and garages.
  • Residential zones: Keeps patios, driveways, and doorways clear of water.

Why Proper Drainage Matters

Without a quality system like the K100, surfaces can quickly flood, leading to unsafe conditions, structural damage, and costly repairs. A trench drain prevents water buildup by collecting and directing flow efficiently.

System Features

  • Boltless locking: DrainLok® / QuickLok® allows for easy grate removal.
  • Anti-shunt lugs: Keep grates stable under load.
  • Numbered channels: Simplify installation and maintain slope order.
  • Grate styles: Stainless, mesh, slotted, or ductile iron—up to Load Class E.
Tip: For heavy debris or snow conditions, opt for wide-slot grates to minimize clogging and simplify cleaning.

Planning & Installation

  1. Survey runoff: Identify where water collects and flows.
  2. Select outlets: Use end, bottom, or catch basin outlets.
  3. Measure length: Each K100 section is 39.37″—plan extras for trimming.
  4. Set slope: Supports up to 130 ft continuous slope for effective flow.
  5. Pick grate class: Choose according to expected traffic loads.

Basic Steps

  • Excavate trench and prepare bedding.
  • Install channels in order, following numbering for slope alignment.
  • Haunch with concrete and finish grade level to surface.
  • Secure grates using DrainLok® or QuickLok® for tool-free access.

Case Study: Municipal Garage Ramp Drainage

Challenge: A city garage ramp frequently flooded at its base, creating icy conditions in winter.

Solution

  • Installed a 120-ft run of ACO K100 channels sloped to a catch basin.
  • Used ductile iron grates (Class E) for durability against heavy traffic.
  • Selected QuickLok® for fast, bolt-free maintenance access.

Results

  • Flooding eliminated even during heavy storms.
  • Lower maintenance time thanks to easy grate removal.
  • Improved safety—no slip incidents recorded after installation.
