Who doesn’t dream of a garden in the city or a green extension?
Who doesn’t dream of a garden in the city or a green extension? Take the plunge and convert your roof to a green roof. Between extensive with sedum plants or intensive roofing with trees and plants your heart will sway. For immediate results and lightweight structures, opt for the complete system of pre-cultivated sedum slabs, Derbisedum Pack, which requires little maintenance. On your roof, you can even take care of a real garden with trees, plants and lawn. Growing your own vegetables on your roof garden is perfectly possible, just like the Foodmet did at the slaughterhouse in Anderlecht. Mmmm! What a joy it is to cook the tomatoes from your own garden!
No matter what your green roof is, it is mandatory that it is perfectly watertight. Derbigum SP AR, Derbigum GC AR, reinforced membrane and Vaeplan V, a synthetic anti-root membrane in itself are the best allies for long-lasting waterproofing.
For better health
It is proven that nature has a positive impact on our health. Looking at nature improves our attention and concentration and reduces stress-related hormone levels. It promotes our well-being! It develops biodiversity in the heart of our cities because plants provide cover for the bees in hives on rooftops, as in Paris. Plant photosynthesis helps to reduce CO2 emissions for healthy air as you know.
All-in-one system
3 Derbisedum Pack tile systems are available: classic – light – biodiversity. They are composed either of a selection of sedum varieties specific to the roof and very resistant to winds of up to 200 km/h, or a mix of sedums and grasses for more diversity. The Light system is best suited to light substrates such as wood and steel. In any case, regular watering is necessary in dry weather.
Regulated rainwater
The Derbisedum Pack’s honeycomb trays retain water in their reservoir. A good idea for less frequent watering! They also act as a buffer to regulate the flow of rainwater into the drainage system and into the ground during heavy rains; this seriously limits flooding. Water for plants? Yes, but not too much!
