Fritz Ulrich School, Heilbronn
The principle of the sponge city (also known as "Sponge City") is an innovative urban planning concept that aims to make cities more climate-resilient and liveable. Building on this principle, the comprehensive renovation of the Fritz Ulrich School in Heilbronn involved redesigning the southern schoolyard. Here, the asphalt was removed to make room for more lawns and planting beds. For the paved areas, GDM.KLIMASTEIN was chosen, which heats up less and has the advantage of allowing rainwater to seep away through the joints.
The use of this stone helps to prevent localized flooding by preventing water from running off the surface. This relieves the burden on the sewer network and thus saves rainwater charges and investment in drainage systems. Thanks to these properties, the GDM.KLIMASTEIN makes a significant contribution to ecological sustainability and to improving the urban microclimate.
