Structured medium for the cultivation of greenery and a waterproofing system to facilitate the installation of said medium on buildings

A structured medium for the cultivation of greenery comprising:

• three vertically stacked layers of which at least the top two consist primarily of synthetic fibers;
• the topmost layer being a cultivation layer which facilitates germination and cultivation of greenery such as turf and having fiber density, ventilation and moisture retention characteristics which lie in between those of the other two layers;
• the middle layer being a protection layer supporting roots of said greenery and providing an adequate level of ventilation and having fiber density and moisture retention characteristics greater than those of the other two layers;
• and
• the bottom layer being a drainage layer supporting said cultivation layer and said protection layer and providing a level of ventilation higher than that of the other two layers, as well as considerable drainage capacity and a measure of elasticity;
• and wherein said cultivation layer and said protection layer each are made of a non-woven fabric consisting essentially of synthetic fiber.
