About the K100 System

In simple terms: The K100 trench drain system captures surface runoff and directs it away from traffic zones, walkways, and buildings. Each 39.37″ modular section connects seamlessly, making it suitable for projects of any size.

Applications:

  • Urban streets: Handles stormwater in high-traffic areas.
  • Parking facilities: Prevents puddles in lots and garages.
  • Residential zones: Keeps patios, driveways, and doorways clear of water.

Why Proper Drainage Matters

Without a quality system like the K100, surfaces can quickly flood, leading to unsafe conditions, structural damage, and costly repairs. A trench drain prevents water buildup by collecting and directing flow efficiently.

System Features

  • Boltless locking: DrainLok® / QuickLok® allows for easy grate removal.
  • Anti-shunt lugs: Keep grates stable under load.
  • Numbered channels: Simplify installation and maintain slope order.
  • Grate styles: Stainless, mesh, slotted, or ductile iron—up to Load Class E.
Tip: For heavy debris or snow conditions, opt for wide-slot grates to minimize clogging and simplify cleaning.
