  • Customizable Layouts: Available in 6-ft sections with cut-to-length capability, plus a full set of elbows, tees, outlets, and caps.
  • Grate Variety: Decorative and functional grate options in plastic or brass to suit design and traffic needs.

Where It Works Best

  • Patios & Terraces: Maintain dry seating and entertainment areas without bulky drains.
  • Walkways & Side Paths: Prevent puddles that can lead to slick surfaces or foundation damage.
  • Pool Decks: Capture splash-out water and direct it safely away from coping and grout lines.
  • Driveways (with rated grates): With heavy-duty grate styles, handle cars and light trucks.

Installation Overview

Plain English: Lay, anchor, connect, and cover—the system is modular and straightforward.
  1. Excavate & Prep: Dig a trench ~4–5″ wide, set bedding material for stable grade.
  2. Place Sections: Insert Mini Channel sections; cut to length as needed.
  3. Secure with Anchors: Use anchoring flanges to lock channels in place.
  4. Connect Grates & Outlets: Choose decorative grates; connect outlets to drainage lines or basins.
  5. Backfill & Finish: Surround with concrete, pavers, or deck material flush to grate height.

Case Study: Patio + Driveway Combo

Location: Residential patio with adjacent driveway • Problem: Rainwater pooled near the back door and ran across a driveway, causing surface staining and minor cracking.

Solution: An NDS Mini Channel Drain was installed across the patio edge and extended into the driveway. Decorative plastic grates matched the patio finish, while heavy-duty grates in the driveway provided vehicle support. Outlets tied into an underground dry well.

  • Install time: 1½ workdays (two-person crew).
  • Outcome: Both patio and driveway remained dry; homeowner avoided costly repairs.
  • Homeowner notes: “The decorative grates blend in beautifully—and it just works.”

Maintenance Tips

  • Check grates quarterly for debris; snap out for easy rinsing.
  • Brush with a nylon brush for stubborn buildup.
  • Inspect outlet connections annually for secure flow.
