What Makes the K100 Effective?

Simple explanation: The K100 is a linear trench drain that captures sheet flow across surfaces. Its modular 39.37″ sections can be joined to create extended runs that direct water toward a chosen outlet point.

Best uses include:

  • Residential driveways and patios: Prevents pooling near entryways and structures.
  • Commercial sites: Maintains clean surfaces in parking lots and loading zones.
  • Parks and pathways: Keeps walkways clear of puddles while blending into the landscape.

Key Features

  • DrainLok® & QuickLok®: Boltless grate locking for easy removal and cleaning.
  • Anti-shunt lugs: Stop grates from sliding under heavy loads.
  • Numbered channels: Maintain slope consistency and correct sequence during install.
  • Multiple grate options: Stainless, slotted, mesh, or ductile iron—rated up to Class E.

Grate Selection & Load Ratings

Load classes simplified: Grates are tested for durability. Class A–C is for light traffic, Class D handles occasional trucks, and Class E supports heavy-duty vehicles.

Looks vs strength: Stainless and powder-coated grates add polished aesthetics, while ductile iron provides the heavy-duty reliability needed for industrial or high-traffic spaces.

Tip: If you expect snow plows or high debris loads, choose wide slotted grates and take advantage of tool-free locking for quick cleanouts.

Edge Rail Options

  • Galvanized steel: Budget-friendly corrosion resistance.
  • Stainless steel: Premium option for coastal, foodservice, or architectural projects.

Planning & Installation Steps

  1. Survey runoff: Identify ponding spots and flow directions.
  2. Select outlet type: End, bottom, or catch basin depending on design.
  3. Count channels: Each piece is 39.37″; add extras for trimming.
  4. Set slope: Continuous slope possible up to 130 ft for fast flow.
  5. Pick grate class: Match expected traffic and site needs.
  6. Add accessories: End caps and transitions for a clean finish.

Install Overview

  • Excavate trench and prepare bedding.
  • Place numbered channels in sequence and secure with concrete haunching.
  • Finish surface level and protect during curing.
  • Snap in grates using DrainLok® or QuickLok®.

Case Study: Garage Ramp Drainage Upgrade

Challenge: A public garage ramp had frequent pooling at the base, creating hazards during winter.

  • Enabled easy maintenance with QuickLok® boltless grate locking.

Results

  • Improved safety: Eliminated pooling and slip hazards.
  • Lower maintenance: Grates lift easily for seasonal cleaning.
  • Better performance: System handles runoff efficiently, even during storms.

FAQs

Can I use the K100 in a residential driveway?

Yes. Pair with Class B–C grates and proper slope to direct water to the outlet.

How often should I maintain the channel?

Inspect after heavy rains and seasonally. Tool-free grate removal makes this quick and simple.

When is stainless steel the right choice?

Use stainless for coastal, foodservice, or high-visibility projects where corrosion resistance matters most.
