Intensive | roof with limited fall
The ideal system for installing an intensive green roof with vegetation such as grass, shrubs and trees. Suitable for roofs with limited fall.
Our intensive green roof systems are supplied as a complete system, from root-resistant foil to the growing-medium layer. In this composition the growing-medium layer consists only of substrate. The intensive substrate is tailored to the needs of intensive vegetation. The substrate height is determined by the type of vegetation, the desired water buffering and the maximum roof load (view the table below).

Intensive vegetation (in combination with pavement)
ND 5+1 Drainage System; filter layer, drainage layer, protective layer and water buffer layer glued to one product.
Root-resistant waterproofing membrane
A strong core with extra high water buffering dimple
The core of this intensive green roof with a roof construction with limited fall is formed by the ND 5+1 Drainage System on a roll. This multifunctional CE-marked drainage system with high compressive strength protects vegetation against water build-up and at the same time stores water in the built-in water reservoir (5.8 l/m²) for dry periods. The extra high dimple (27.5 mm) of this drainage system ensures that even on roofs with limited fall, the waterproofing membrane is protected against the build-up of water pressure and mechanical loads.
This multifunctional CE-marked drainage system with high compressive strength protects vegetation against water build-up and at the same time stores water in the built-in water reservoir (5.8 l/m²) for dry periods. The high dimple of this drainage system ensures that on roofs with insufficient fall, the waterproofing membrane is protected against the build-up of water pressure and mechanical loads.
If the waterproofing membrane is not root-resistant, we recommend adding the ND WSB-80 Root Barrier.
