Tree granulate is specifically aimed at creating planting areas in heavily burdened situations, such as roads, cycling paths and car parks (traffic category 1 to 5). The tree granulate has a basis of Grauwacke-rubble and ripened clay. The product grows space for tree roots to develop in situations in which strict civil technological demands apply. This makes it possible to develop healthy trees in places where trees would otherwise not grow or would cause problems by causing rootdamage to the pavement. Grauwacke is a naturally broken sustainable stone and conforms to the prevailing environmental classification in accordance with Soil Quality Decree.
