Drainage is an essential component of a green roof: it allows excess water in the plant complex to be evacuated. The advantage of mineral drainage is that it favors the layer explored by the plant’s roots, slightly reducing the thickness of substrate to be used.
Le Prieuré mineral drains can be packaged in bags or Big Bags, and can be applied by blowing.
All drainage systems are components of Le Prieuré’s certified multilayer solutions.
