Elevate Landscape Design with Wallbarn’s Permeate Planter System

Tucked between hard landscaping and lush planting, Wallbarn’s Permeate Planter System is a cutting-edge substructure that offers designers, architects, and developers unrivalled flexibility and performance. This modular, non-combustible framework transforms terraces, rooftops, balconies, and podium decks into dynamic, multifunctional outdoor environments where greenery, seating, paving, and decking coexist seamlessly.

A One-Stop Foundation for Hard and Soft Landscapes

At its core, the system combines Wallbarn’s robust sub-floor – featuring adjustable MetalPad Ex pedestals, lightweight aluminium joists, and galvanised steel trays – with bespoke metal planters and FSC‑certified benches. Together, these elements form a load-bearing “platform” ideal for supporting a variety of finishes, from porcelain and timber decking to stone paving and planted beds.

Precision Engineering for Strength and Drainage

Each component is engineered for performance:

• MetalPad Ex pedestals adjust from 26 mm up to 375 mm, allowing for accurate height control and slope correction.

• I‑Plus aluminium joists, available in 50, 75, and 100 mm profiles, deliver stability without bulk.

• 600×540 mm galvanised steel trays integrate effortlessly onto brackets—no mechanical fixings needed—and incorporate drainage holes to prevent water pooling.

This combination ensures fast, clean installation and a consistently level surface, even over complex roofs or uneven substrates.

Elegantly Integrated Planters

Soft landscaping is woven into the design with built-in planters crafted by Bespoke Metal Planters Ltd. These come in aluminium, galvanised steel, or Cor‑Ten steel, finished with durable powder coatings in any RAL or BS shade. Featuring wall thicknesses of 3–4 mm, they’re built for longevity and root health. Integrated drainage safeguards plant life and prevents water build-up beneath, securing both plant vitality and structural integrity.

Stylish and Sustainable Seating

To complement the planting, Permeate includes seating options that blend design with compliance. FSC-certified hardwood benches offer natural warmth and comfort, ideal for relaxed outdoor settings. For installations where fire regulations are stringent, fully non-combustible metal benches are available. All seating integrates with the substructure, ensuring a streamlined, cohesive finish.

Hard Landscaping Versatility

Complementing plant and seating elements, the Permeate system supports a wide selection of hard surface finishes. From premium porcelain decking to timber-look tiles or natural stone paving, clients enjoy a unified aesthetic without sacrificing performance. All hard surfaces benefit from the underlying drainage strategy and the stability of the support system.

Fire-Safe, Durable, Adaptable

Built from top-tier materials—galvanised steel, aluminium, and optional Cor‑Ten steel with Qualicoat polyester finishes—the Permeate system is non-combustible and fully Class A fire rated. It is designed to resist corrosion, weathering, and UV damage, delivering enduring performance in exposed urban settings Wallbarn.

Simple, Modular Construction

The system is remarkably intuitive to install:

1. Adjust pedestals to establish the base level.

2. Fix aluminium joists with M8 wing-nut kits onto the pedestals.

3. Slide in drainage-ready steel trays onto the joists—no screws needed.

4. Lay finishes—planters, benches, decking or paving—directly onto the trays and joists, each with concealed fixings.

This modular approach means quick build times, minimal mess, and straightforward future access to infrastructure beneath—for example, drainage, wiring or irrigation systems.
