Holstenfleet, Kiel, Germany

Kiel's city centre has been given a new, maritime face. The "Holstenfleet" with its spacious areas, seating and water basins invites visitors to linger and relax. Previously, Holstenbrücke was a six-lane main road and characterised by noise. Today, only public bus traffic travels along it, which decisively reduces exhaust fumes in the city centre. Two water basins visually connect the Bootshafen with Kleiner Kiel. The tree species planted there tolerate the city climate very well. Thus the new "Holstenfleet" is quiet, environmentally and climate-friendly. A clever drainage concept was developed for the open spaces in cooperation with engineers from ACO Tiefbau. The aim was to leave the design of the areas largely untouched.

ACO Combipoint road drains with Multitop design gratings were installed in the traffic and vegetation areas. These are fitted into ramp stones and thus provide safe and at the same time discreet drainage. In addition, ACO protective tree grates were used to protect the soil of the newly planted marsh oaks from excessive compaction and at the same time ensure an adequate water supply for the roots.

In the area around the south basin, ACO DRAIN® Multiline Seal in channels with slotted gratings were installed that integrate inconspicuously into the pavement concept. The channel bodies are concealed under the wooden and concrete slab coverings. Only a narrow visible slot ensures efficient absorption of the surface water. Wooden decks run parallel to the north pool and are arranged as walking and sitting surfaces. Below them are ACO DRAIN® Multiline Seal in channels. They drain the area reliably and quickly.
