Linear Trench Drain System: Complete Guide for Patios, Driveways, Plazas & Walkways

A Linear Trench Drain System is a modular drainage channel engineered to capture and move surface water efficiently. Unlike point drains that rely on single inlets, a trench drain collects water continuously along its length. This makes it the perfect solution for driveways, patios, pool decks, and commercial plazas where wide surface areas demand reliable water management.

Why Use a Linear Trench Drain?

Full-edge protection: Instead of waiting for water to find a small grate, trench drains intercept flow across the full channel width.

Blends seamlessly: With a 4-inch internal width, these drains integrate into both residential and commercial surfaces without becoming visually intrusive.

Consistent drainage: The system supports continuous slope installations up to 130 feet, ensuring reliable water flow even on flat projects.

Key Features

  • Fast installation: DrainLok® and QuickLok® systems make grate removal tool-free and efficient.
  • Accurate alignment: Anti-shunt lugs and numbered channels guarantee proper fit and long-term stability.
  • Grate flexibility: Options include mesh, slotted, perforated, and ductile iron with load ratings up to Class E.
  • Durable build: Available with galvanized steel or stainless steel edge rails for maximum resilience.

Best Applications

  • Driveways & garages: Prevent water from pooling where vehicles and foot traffic intersect.
  • Patios & pool decks: Maintain dry, usable surfaces for safety and comfort.
  • Commercial plazas: Handle heavy pedestrian traffic with sleek integration into design layouts.
  • Industrial wash zones: Manage high-flow wash-down areas with heavy-duty grates.

Sizing & Layout Tips

  1. Map water paths and identify natural low points.
  2. Choose the 4" internal width for most projects; expand depth for higher rainfall zones.
  3. Plan slopes up to 130 feet continuous for effective runoff control.
  4. Match grate style and load rating to your environment and traffic type.
  5. Select galvanized or stainless steel rails depending on durability needs.

Case Study: Urban Plaza Retrofit

Location: City plaza • Problem: Persistent ponding created slip risks and costly cleanup.

Solution: A Linear Trench Drain System with stainless rails and slotted grates over a 100-ft run. Designed with a 0.5% continuous slope and connected to existing storm outlets, the system eliminated surface pooling and reduced drying times after rainfall.

  • Install duration: 3 days, phased around public access.
  • Outcome: Zero ponding recorded during storms up to 2" in 24 hours.
  • Design impact: Drainage integrated seamlessly into the plaza’s stonework.

FAQs

Which grate is best?

Use slotted or perforated grates for patios, and Class E ductile iron for driveways and industrial use.

How often to maintain?

Check quarterly. The boltless locking makes cleaning fast and tool-free.

Does stainless steel rust?

Stainless resists corrosion, especially in harsh environments. Galvanized is suitable for most residential uses.
