Tree granulate is specifically meant for creating planting spaces in heavily burdened areas such as roads, cycling paths and car parks (traffic class 1 to 5). The tree granulate has its basis recycled (broken) stones (Porphyry) and ripened clay and offers grow space for tree roots to develop in circumstances that conform to civil technological demands. This makes it possible to develop healthy trees in areas where trees can either not develop or would cause problems by roots damaging the pavement. Tree granulate is a recycled product. It is not a mineral, but a composite product on the basis of secondary resources and therefore justified in terms of sustainability.
