We’re excited to announce the launch of Aquadrain 50, a high-performance drainage solution, now available for purchase directly from the Sky Garden Shop.

Whether you’re working on a green roof project, a bin store, or a garage roof, Aquadrain 50 is the ideal drainage layer to keep things flowing smoothly beneath the surface.

What is Aquadrain 50?

Aquadrain 50 is a modular, geocellular, interlocking drainage board designed specifically for extensive green roofs and similar applications where a lightweight, high-capacity drainage layer is needed. Manufactured from 100% recycled polypropylene, it combines sustainability with superior performance.

Its 95% void ratio, lightweight build (only 1.1 kg per unit), and impressive compressive strength of 93 tonnes per m² make it a robust solution for green infrastructure.

Key Benefits

Here’s why Aquadrain 50 stands out:

· Sustainable Construction – Made from 100% recycled and fully recyclable polypropylene

· Protects Waterproofing Layers – Acts as a protective layer above membranes

· Exceptional Strength – Supports green roof systems with a high load-bearing capacity

· Efficient Water Management – Retains stormwater while allowing for efficient flow (155.4L/min/unit)

· Promotes Plant Health – The high void ratio encourages aeration for drought-tolerant vegetation

· Easy to Install – Interlocking design simplifies setup and adds lateral strength

Designed for Green Roof Excellence

Aquadrain 50 is engineered to support vegetation that thrives in low-maintenance and low-nutrient environments, such as:

· Sedums and native succulents

· Wildflowers

· Small herbs, bulbs, and alpines

· Carefully selected slow-growing grasses

Whether it’s a public transport shelter, garage, or commercial rooftop, Aquadrain 50 provides the foundational drainage your living system needs without the bulk and complexity of traditional systems.

Where to Use It?

Perfect for non-traffic-loaded roof applications, Aquadrain 50 is commonly used in:

· Garage and bike store roofs

· Green roofs on habitable and non-habitable buildings

· Public shelters and green infrastructure projects

Each unit measures 500mm x 500mm x 50mm, with four units covering a square metre—making it both scalable and practical for projects of all sizes.
