The green roofs can be roofs of buildings, as well as roofs of parking lots and garages. In order for such green roofs to be constructed, the roof of the structure itself should be built with the implementation of a green roof area in mind.
Besides soil or inert substrate, which is poured onto the roof, the structure must be consistent with the vegetation that will grow on the roof over time and will increase its mass and volume.
During the process of construction of the green roofs reliable waterproofing has to be provided, which needs to be resistant to the mechanical actions of the root system of the plants, as well as to the effect of various chemical fertilizers, herbicides, insecticides and other chemicals used for the maintenance of the green areas.
The green roofs can have only a decorative and ecological function, but at the same time they can also be loaded with movement and stay of people and animals on them.
This should be known in advance, so that the construction and the insulation layers of the slab on the roof to provide the suitable thickness, reinforcement and abrasion resistance.
In Bulgaria the green roofs are not yet sufficiently popular or most often they are implemented as concrete platforms on which later are arranged pots and flower beds with plants.
However, we know everything about the true green roofs – how they should be built and how should they look like even years after they have been completed.
We know how to design, implement and maintain the true green roofs, so that their appearance and durability will remain for years after being built.
