Planted with sedum with the option of additional pathways for user access, EvaGreen® extensive roofs are especially low maintenance and often do not require irrigation. They offer all of the environmental and structural advantages of intensively planted rooftops with naturalistic plant styles that are for the most part self-supporting.

EvaGreen® extensive roofs are planted in a medium of carefully selected and tested organic matter and minerals free from building rubble and contaminants. 


Intensive planting is a mix of plants, shrubs and trees complemented by walkways, terraces and turfing. Similar to any conventional, ground level garden, it offers the same benefits and provides a superb environment for relaxation alongside environmental benefits.

EvaGreen® intensive roofs are planted in a medium of high density organic matter and minerals free from building rubble and other potential contaminants. 


This type of roof garden basically allows nature to take its course. The substrate on which the plants survive is provided by rubble ideally from the ground excavations of the building the roof garden will sit on. It is usually only necessary to provide protection to the roofing membrane and some facility to ease draining; we recommend the Terradrain D6 for this purpose.
