Weiterentwicklung von Wurzelschutz-Polymerbitumenabdichtungsbahnen als wichtiges Element der grünen Infrastruktur im urbanen Raum.
Abstract
Green areas, but especially green roofs and facades, are becoming increasingly important as they can significantly improve the climate in urban areas. For the sealing of green roofs, bitumen membranes are often used, which contain chemical root protectants (pesticides), which are to avoid the damage caused by ingrowing plant roots. Investigations from Switzerland and Germany have shown that these substances are released from the bitumen membranes under the natural weather conditions and washed out with the precipitate. Since the most commonly used pesticides for this purpose have a low elimination rate in sewage treatment plants, there is a particularly high risk potential for surface waters. In the case of decentralized rainwater infiltration there is a risk of soil and groundwater contamination. In addition, the leaching of such materials from bituminous membranes can lead to significant adverse effects on rainwater harvesting in the context of decentralized rainwater management concepts. Consequently, the development of "green" (pesticide-free) solutions is an important concern for the whole society. The company Slavonia, in cooperation with the BOKU, has taken on this task and is already working on the development of pesticide-free bituminous membranes. The aim of this collaboration is to further develop root-resistant seals in such a way that either no more biocides are necessary to use or remain in the product over long term, thus avoiding the burden on the environment.
