The Zurn Promenade Deck Drains are engineered to deliver both visual appeal and reliable drainage for rooftop and deck applications. Designed specifically for promenade decks, paver systems, and pedestrian-friendly rooftop surfaces, these drains ensure effective water management while maintaining the integrity of decorative flooring layouts.

Key Features

Where Z158 Works Best

  • Roof terraces, promenades, and rooftop plazas
  • Decks with tile, stone, or modular paver patterns
  • Public/pedestrian spaces needing flush, low-profile drains

Installation Best Practices

Quick tips for performance and appearance:

  • Set the drain flush with the finished surface to avoid trip hazards.
  • Plan grate orientation with your paver layout before final setting.
  • Create positive slope to the drain; avoid flat spots that cause ponding.
  • Integrate waterproofing carefully around the body to prevent infiltration.
  • Maintain seasonal access for debris removal and inspection.

Case Study: Terrace Walkway

Challenge: A rooftop promenade needed discreet, effective drainage that wouldn’t break the paver grid lines.

Solution: Designers specified Zurn Z158 drains at low points. The square grates aligned with the paver joints, and the flush install preserved clean sightlines.

Outcome: The walkway drains reliably during storms, maintenance is simple, and the intended aesthetic remains intact.

Conclusion

The Zurn Z158 10" Square Top Prom-Deck Drain brings design harmony and dependable drainage to terraces, promenades, and plazas—perfect where visual order and performance both matter.
