Why Choose the K100?

In everyday terms: The K100 is a trench drain system designed to catch runoff across wide surfaces and direct it safely away. Its modular sections fit together for long runs, preventing standing water around structures and traffic zones.

Perfect for:

  • Homes: Stops water pooling near foundations and garage entries.
  • Commercial sites: Protects paved areas and walkways from flooding.
  • Public spaces: Keeps plazas and parks dry and safe for pedestrians.

Features & Grate Options

Features explained:

  • DrainLok® / QuickLok®: Bolt-free locking for fast grate removal.
  • Anti-shunt lugs: Keep grates locked firmly under wheel loads.
  • Numbered channels: Simplify slope installation and alignment.
  • Wide grate range: Mesh, slotted, perforated, or ductile iron—rated up to Class E for heavy-duty loads.

Choosing grates: Stainless and powder-coated grates enhance appearance in high-visibility areas, while ductile iron provides maximum durability for industrial traffic. Always match the grate class to expected loads for safe performance.

Tip: If your project sees snow plows or gravel runoff, choose larger slotted grates for better flow and easier seasonal cleaning.

Planning & Installing the System

  1. Survey runoff: Mark ponding areas and natural water flow.
  2. Select outlet: Choose between end outlets, bottom outlets, or basins.
  3. Calculate sections: Each is 39.37″—add extra for trimming.
  4. Set slope: Supports continuous slopes up to 130 ft; target 0.5–1% for best results.
  5. Pick grate strength: Match the heaviest expected traffic.

Installation Steps

  • Excavate trench and prepare bedding.
  • Install channels in numbered order and secure with concrete haunching.
  • Backfill and level surface to match grade.
  • Place grates using DrainLok® or QuickLok®.

  • Chose QuickLok® for fast, tool-free grate removal during monthly inspections.

Results

  • No more pooling at ramp base during rainstorms.
  • Reduced maintenance with quick grate access for cleaning.
  • Improved safety with zero slip incidents after installation.

FAQs

Can I install the K100 for a home driveway?

Yes, pair it with Class B–C grates and proper slope for effective drainage.

When should I choose stainless rails?

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