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.


Your flat roof project is an achievement for life. Are you hesitating and would you like to be inspired by the realisation of other buildings similar to yours? Let yourself be inspired … by building sites where the Derbigum SP FR membrane has added that extra touch that makes all the difference.
