Understanding the K100 System

In plain terms: The K100 is a linear drainage system made of 39.37″ channels that connect seamlessly to form long runs. This design efficiently captures surface runoff along driveways, sidewalks, plazas, and other hardscapes where water tends to spread out.

Ideal uses:

  • Residential driveways and patios: Prevents pooling around entries and garages.
  • Parking lots & commercial walkways: Captures widespread runoff where point drains fail.
  • Public parks & plazas: Maintains safety and appearance with discreet water control.

Key Features Explained

  • DrainLok® & QuickLok®: Grates lock in place without bolts for tool-free removal.
  • Anti-shunt lugs: Prevent sideways grate movement under traffic loads.
  • Numbered channels: Ensure slope consistency and correct installation order.
  • Multiple grate styles: Stainless, slotted, mesh, or ductile iron—rated up to Class E.

Choosing Grates & Load Ratings

Load ratings simplified: Grates are tested for how much weight they can withstand. Class A–C is for pedestrians & light traffic, Class D handles occasional trucks, and Class E supports heavy-duty vehicles.

Style vs. function: Stainless or powder-coated grates provide a polished look for public spaces, while ductile iron grates offer rugged strength in industrial zones. Select the grate pattern based on traffic, debris load, and appearance needs.

Tip: For areas with snow plows or heavy debris, use wider slotted or ductile iron grates and take advantage of boltless locking for easy seasonal cleanouts.

Edge Rail Options

  • Galvanized steel: Affordable, reliable corrosion resistance for general outdoor use.
  • Stainless steel: Premium option for coastal zones, food prep areas, or architectural finishes.

Planning & Installing the K100

  1. Map surface water: Identify ponding spots and runoff direction.
  2. Select discharge: End outlet, bottom outlet, or catch basin depending on site layout.
  3. Calculate channels: Each is 39.37″—add extra for trimming and connections.
  4. Set slope: Continuous slope up to 130 ft; target 0.5–1% for self-cleaning flow.
  5. Match load class: Choose the correct grate strength for expected traffic.
  6. Install accessories: End caps, transitions, and outlets for alignment and sealing.

Installation Highlights

  • Excavate trench and prepare bedding.
  • Set channels in order by number; secure with haunching concrete.
  • Finish surface grade and protect edges during curing.
  • Place grates using DrainLok® or QuickLok®—no tools needed.

Case Study: Municipal Garage Ramp with K100

Problem: A municipal garage ramp experienced frequent pooling at the base, leading to icy conditions in winter.

Solution

  • Installed a 120-ft run of K100 channels sloped to a central basin.
  • Used ductile iron grates (Class E) to handle light truck traffic.
  • Adopted QuickLok® grates for monthly cleanouts without tools.

Results

  • Water redirected before reaching pedestrian areas.
  • Maintenance reduced thanks to tool-free grate removal.
  • Improved safety with no slip complaints after installation.

FAQs

Is the K100 suitable for residential driveways?

Yes, use a Class B–C grate and provide slope to ensure flow toward an outlet.

How often should maintenance be performed?

Inspect seasonally and after storms. Boltless grates make removal simple and fast.

When is stainless steel preferred?

Use stainless where corrosion resistance and aesthetics are priorities, such as coastal or high-visibility projects.
