A green roof terrace was chosen for the annex to the Lomme hospital

A water retention capacity of 7 l / m 2

The so-called simple extensive roof greening system, which was chosen to cover the roof terrace of the former hospital parking lots, is made up of succulent, creeping and resistant plants: sedums, whose foliage color changes with the seasons. . The advantage of this solution is linked to its low weight (from 60 to 100 kg / m²) and its reduced maintenance. It is also recommended for the realization of urban vegetable garden. A drain elevates the system and prevents root suffocation due to excess water. Its characteristic is also to store water for plants. For the realization of this green roof, Ecovégétal supplied the DK20 water retention drains in high density polyethylene with geotextile with a height of 20 mm. They offer a water retention capacity of 7 l / m². Ecovégétal delivered the Succulis rugs. The sedum mat or Succulis mat is biodegradable and pre-cultivated outdoors with different varieties of sedum, adapted to the local climate.
