BSI Tree granulate Grauwacke 16-32

Characteristics
Tree granulate BSI Grauwacke 16-32 is specifically intended for creating growing places
under heavily loaded situations such as roads and parking lots. The tree granulate has as a base in three directions sharply angled Grauwacke quarry stone 16-32 mm, made of matured river clay, organic matter and  food additives. In conditions where it has been processed in accordance with strict civil engineering requirements, it offers growing space for tree roots to develop. This makes it possible to develop healthy trees in places where trees would otherwise not develop or cause problems with, for example, pavement pressure. The tree granulate also offers a solution for locations where flooding during heavy rain showers is a problem. The large pore volume ensures a lot of water storage in a short time. The tree granulate is a composite product based on the Handboek Trees 2018 with a low pH. This product is made from 100% natural raw materials.

BSI Grauwacke 16-32 tree granulate is produced and delivered with an FEV statement. This means that BSI Grauwacke 16-32 tree granulate meets the strictest quality requirements, including the requirements for an undesigned building material from the Soil Quality Decree.
