Balcony Decking Edge & Full Perimeter Drainage

Balcony and terrace surfaces require a reliable drainage solution to prevent water buildup, reduce pooling, and protect the structural integrity of the substructure in compliance with BS 8579. The edge and perimeter drainage systems provide an efficient way to channel water away from the surface, ensuring a dry and safe environment for both residential and commercial applications.

How It Works

The perimeter drainage system is fed water running from an imperforate decking layer, either to 1 side or up to all 4 edges. A discreet drainage gap allows water to flow into the drainage channel and is then directed to a water outlet. A threshold drainage channel can also be incorporated to capture and channel water from the building edge.

Why Perimeter Drainage Matters

Edge and perimeter drainage systems focus on collecting and redirecting water at the boundaries of the decked surface. This method minimizes standing water and supports overall system longevity.

Key advantages include:
✔ Optimized Water Flow – Designed to guide water toward designated drainage points, reducing excess moisture on the deck surface.
✔ Structural Protection – Helps prevent water infiltration into the substructure, preserving materials like aluminium joists and pedestals.
✔ Compatibility with Balcony Systems – Works seamlessly with Low-Fix, Aqua-Channel and Strong-Span aluminium decking installations.
✔ No Balcony Soffit Required – For balconies where a soffit water collection system is not possible, this acts as a perfect solution to collect water over the full balcony footprint.

Applications

  • High-rise residential balconies
  • Commercial terraces and podiums
  • Steel-framed balcony installations
  • Rooftop decking and outdoor spaces

More Drainage Solutions

  • Soffit Drainage

    The soffit drainage system is designed to manage water runoff by integrating drainage components beneath the deck surface, ensuring a controlled and efficient removal of excess water.

  • Hopper System Drainage

    For commercial balconies and terraces requiring an efficient and high-capacity drainage solution, the hopper system drainage provides a robust method of collecting and directing water runoff.
