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.

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.

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.
