Roof garden & planted areas Intensive green roof/Extensive green roof 1.  Information about Green Roof Systems Intensive green roof For landscape development, the choices are vast and leave full liberty to the creator who will be defining the works within a specific green space project. This type of roof garden (or planted area) is called “intensive” because of the intensive maintenance to expect when planning this type of roof. Extensive green roof Green roof system with low maintenance and no irrigation required in Northern European regions. In Southern regions, automated watering network...

2.  Choosing appearance of roof garden For intensive green areas: the choice of landscaping is vast and leave full liberty to the creator: lawn, shrubs and trees. The soil thickness needs to comply with the type of plantation. For extensive green roofs: there are mainly 3 approaches to select the appearance of a roof garden according to the type of selected plant varieties and the different systems of pre-grown vegetation available on site such as: pre-grown modular green roof pack (“Hydropack” type or similar); or vegetation blankets (“Gravi-Tapis” type or similar); or seedlings in...

Roof garden & planted areas Intensive green roof/Extensive green roof 3. Choosing the way of installation The methods available for putting out vegetation in roof locations involve the use of: Pre-grown elements such as :pregrown modular green roof pack (“Hydropack” type or similar) or vegetation blankets (“Gravi-Tapis” type or similar). Seedlings in miniature turf squares (“Gravi-Motte Sedum” , “Gravi-Motte Perennial” types or similar). Segregated seeding elements (“Gravi-Fragment” type or similar). Important! The choice of type of roof plantation has a direct influence on: Site...

4.  Maintenance The maintenance for roof gardens using these systems is undemanding, although some maintenance is essential, especially during the first three years. Maintenance helps stabilise the growth process in its environmental ecosystem, particularly if plants are seeded out, or planted out as seedlings. As a waterproofing contractor, you need to keep at your disposal professional advice or assistance on the maintenance of extensive roof gardens. Spraying of Graviflor growing substrate Laying of vegetation blankets (“Gravi-Tapis” type) Micro-turf plantation Removal of unwanted growth...
