The Three Layers of Green Roofs Explained.

Our Drainage Layer (With Root Expansion Zones)

The root system is the work force of the plant. Its where vital food and water is absorbed. Its crucial to make sure the root system is as healthy and strong as possible. Our layer is designed to give the plant roots extra room to breathe, expand and absorb more water. This will maintain healthy foliage and avoid the dark red shading of stressed Sedum. 

  • 30mm layer to filter out water 
  • Creates a skeleton for root structure to travel through 
  • A strong expansive root system is crucial for plant strength 

Our Substrate (Growing Medium)

Blended locally and tested at Sheffield University to the German FLL Standard. Green roof plants need to grow in a lightweight medium that is porous, that holds oxygen and water and retains nutrients. It must provide stability for the plants’ root systems. These can be difficult and opposing goals to achieve and must be in balance. Good substrate is the key to success for a Green Roof. 

Our Vegetation Layer (The Plants)

Our careful plant selection is essential to the success of the green roof. They are long lived and had have the ability to self-propagate. Our plants are irrigated with mineral water from our bore-hole and are naturally fertilized with sea-weed extract. This promotes a really healthy root system.
