MENY (Mother Earth Needs You) trees: Filtersubstrate und revolutionäre Bautechniken zur raschen Begrünung im Retrofit

Development of a method for minimally invasive and millimetre-precise milling of tree pits (min. 1200 mm diameter) in existing asphalt and concrete surfaces using core drilling equipment, excavation of planting pits (min. 1500 mm deep) in different soil types, quick and easy temporary securing of planting pits, efficient and fast soil loosening. Development of a method for creating aeration holes (min. 100-160 mm diameter) including soil loosening (min. 1200 mm depth) and identification of suitable filling and sealing materials for the creation of surfaces that comply with ÖNORM B 1600. Development of a method for the minimally invasive creation of permanent and temporary irrigation solutions. Creation of microtrenching milling for the rapid laying of supply lines, identification of suitable irrigation controls, sensors and pipes. Development of a new, optimised and precisely fitting tree surround including root ball support that can be manufactured cost-effectively and in series. Development of a modular tree impact protection system. Development of a suitable biotech filter substrate that enables the discharge of surface water in accordance with ÖNORM B2506-3 despite low substrate volume and provides all necessary filter performance in the long term.
