A comprehensive guide to specialist
green roof growing media and sources of
information for enterprises involved in the
creation and design of sustainable
Green Roof solutions.
All our media are based on specially matured and graded green compost to provide optimal stability and nutrition. All Vital Earth composts are sanitised and weed-free – thanks to our unique cutting edge composting technology. Carefully selected and size-graded crushed brick is added to create optimal air:water holding properties.
Minimal leaching of nitrogen, phosphate and organic matter
Run-off attenuation
Excellent plant establishment with strong root growth and healthy top growth
Nil slumping
Vital Earth growing media can be installed by blower truck as well as conventional means.
For an explanation of the characteristics of green roof types and Sedum Mats, see our 'Green Roof Type' Page
Based on 14-5 mm recycled clean brick and 25-10 mm mature green compost. To ensure sustained optimal drainage properties, only dust-free brick is used. The medium provides a long-lasting reserve of major nutrients and trace elements with minimal water-soluble nitrogen to prevent soft growth.
This free-draining medium protects Sedum from invasion by aggressive weeds, heavy rainfall and severe cold.
Ideal for installation of Sedum as mat or plugs using a layer 75 mm deep.
Based on 5-2 mm recycled clean brick and <10 mm mature green compost. To ensure sustained optimal drainage properties, only dust-free brick is used.
This well-balanced medium provides protection from severe weather conditions including heavy rainfall and intense frost.
Ideal for establishment of a Meadow roof (using mat, transplants, or seed) using a layer at least 100 mm deep.
Like Meadow Roof Medium, Lawn Roof Medium is based on 5-2 mm recycled clean brick and <10 mm mature green compost but it also contains sterilised recovered topsoil to enhance establishment of the sward, whether based on cultivated or wild cultivars.
It is also suitable for grass/meadow flower mixtures.
Best used at 150 mm or more.
Specially developed to suit the latest techniques in Sedum Mat production, Sedum Seed Medium is based on 5-2 mm brick, 8 mm green compost, sterilised recovered topsoil and 8 mm composted conifer bark (FSC-sourced).
Usually applied as a 20 mm layer on a fabric base, it provides excellent germination and subsequent growth.
It can also be used to root Sedum cuttings broadcast over the surface.
