WE 25/15 – The Pressure-Resistant Solution - is the ideal basis for a biodiverse green roof. The high water storage capacity of WE 25/15 allows for a wide range of plants for greening. Modest perennials in combination with our seed mixture “Bee, Bumblebee & Co” offer a wide range of food for insects and birds from early spring to late autumn.
WE 25/15 – The Pressure-Resistant Solution – is a stable underground for a variable structured surface with here and there ridged up substrate, deadwood, stone cairns, puddles of water and sandy areas. A habitat designed like this provides an attractive refuge, hiding places and nesting aids for animals and plants. Biodiversity green roofs of this type promote biological diversity.
