What the K100 Is—and Where It Shines

Plain-English definition: A trench drain is a long, narrow inlet that captures sheet flow and directs it to a safe outlet. The K100 uses 1-meter channels that link together, creating a continuous intake “slot” along drive lanes, sidewalks, and hardscapes.

Best-fit applications:

  • Parking areas & ramps: Continuous capture where spot inlets miss spread-out runoff.
  • Walkways, plazas, and courtyards: Architectural look with effective drainage.
  • Residential driveways & patios: Keeps water away from garages and thresholds.

Key Features (Explained in Simple Terms)

  • DrainLok® & QuickLok® boltless locking: Grates pop in/out without tools—speeding up cleaning and avoiding rusted hardware.
  • Anti-shunt lugs: Tiny stops that keep grates from shifting sideways under tire loads.
  • Numbered channels: Each piece is labeled to maintain your designed slope and flow direction during install.
  • Grate options up to Class E: Stainless/mesh/slotted for public spaces, ductile iron for heavy-duty vehicle lanes.

Grate Selection & Load Classes

How load classes work: Grates are rated for expected traffic. Higher class = stronger grate. Generally, Class A–C suits pedestrians/light vehicles, Class D handles occasional trucks, and Class E supports heavy-duty zones like service lanes.

Appearance vs. performance: Stainless or powder-coated grates provide a refined look for visible areas; ductile iron is the durable choice for industrial or heavy-vehicle sites. Slotted or mesh patterns balance open area, debris tolerance, and heel safety.

Pro tip: In snowy or gravel-prone regions, choose a grate pattern with larger openings and take advantage of the boltless locking for quick seasonal cleanouts.

Edge Rails: Galvanized vs Stainless

  • Galvanized steel: Cost-effective corrosion protection for most outdoor environments.
  • Stainless steel: Ideal near coasts, foodservice areas, or where premium appearance matters.

Planning Slope & Layout (Step-by-Step)

  1. Map runoff: Mark high points and ponding zones to position the line.
  2. Pick an outlet: End outlet, bottom outlet, catch basin, or a downstream pipe.
  3. Count channels: Each K100 is 39.37″; add 5–10% extra for cuts/contingencies.
  4. Design slope: Continuous slope available up to 130 ft; aim ~0.5–1% for self-cleansing flow.
  5. Choose grates: Match the heaviest expected load to keep costs controlled yet safe.
  6. Plan accessories: End caps, transitions, and outlets to maintain fall and alignment.

Install Overview

  • Excavate trench allowing for bedding and concrete haunching (per manufacturer guidance).
  • Set string line/elevations; place numbered channels in order and connect.
  • Backfill and haunch in concrete; protect tops during cure.
  • Install grates with DrainLok® or QuickLok®—no bolts to lose or seize.
Maintenance: Lift grates tool-free, remove debris, and flush the run. Boltless locking keeps routine cleanouts quick.

Case Study: Garage Ramp Retrofit with K100 (120-ft Run)

Site: Two-level public parking garage experiencing ponding at the ramp transition.

Challenge (plain terms): Wide sheet flow pooled at the ramp bottom, creating slip hazards and winter icing.

Solution

  • Installed a 120-ft K100 line with numbered, sloped channels to a central outlet.
  • Selected ductile iron grates (Load Class E) for occasional truck traffic.
  • Chose QuickLok® for fast, bolt-free monthly cleanouts.

Results

  • No standing water at the ramp after storm events.
  • Shorter maintenance cycles—no more seized bolts during grate removal.
  • Improved safety with zero slip complaints recorded in the first quarter after install.

Quick Specs & Selection Checklist

  • Channel length: 39.37″ (1 meter)

Before You Order

  • Confirm total run length and channel count (add 5–10% buffer).
  • Match grate load class to your heaviest traffic.
  • Decide on discharge method and required accessories.

FAQs

Is the K100 suitable for residential driveways?

Yes. Use a Class B–C grate and maintain proper slope to the chosen outlet.

How often should the channel be cleaned?

Inspect seasonally and after major storms. Boltless locking makes grate removal fast, encouraging routine maintenance.

When should I pick stainless edge rails?

Choose stainless for coastal areas, foodservice environments, or premium architectural finishes where corrosion resistance and appearance are critical.
