55 % of the world’s population lives in cities – a number which rises every day. To make room for the increasing amount of inhabitants houses and apartments are built, but at the same time, it is vital to make space for green, recreational areas that have proven to improve the well-being for the people in the cities.

Smart rainwater management solves more problems in the cities

In the coming years, many larger cities have to come up with solutions for the challenges of increasing amounts of rainwater and more extreme weather. By implementing solutions that help protect densely populated and developed areas against flooding, the development of the square serves as an example to be followed when the rest of the city is to be climate-proofed. By actively making use of a city’s green areas in the fight against pollution and securing the city against cloudbursts, smart ways of handling rainwater solve a great deal of the problems, cities today are facing.

From industry to recreational area

The harbour in Aarhus went through a significant transition in 2011-15 from being an industrial area to becoming a space of recreation with coherence to the city centre of Aarhus, the cathedral, the pedestrian street, and the environment along the stream, flowing through the city. The city wanted to change the landscape of the city and give trees and plants a central role, making the townscape look and feel greener and better to live an be in.

Green urban spaces create well-being

Planting trees in urban zones have many advantages. Not only do the residents become happier by looking at and spending time in green surroundings; they also improve the urban climate. Trees cleanse the air and have the ability to lower the temperature in the city. The positive impact of the trees, however, won’t happen until they have grown to a certain size but with many large areas with hard surfacing, which minimises oxygen levels in the soil and prevents the roots of the trees in obtaining rainwater, it can be challenging to maintain right growing conditions for the urban trees.

Optimal growing conditions for urban trees

To give the trees the best conditions to grow strong and tall and create a beautiful, green urban space, it is essential that the soil stays uncompressed. That may be a challenge, especially on squares with the hard surfacing. Therefore, the new urban trees at Aarhus Harbour have been planted using StrataCells growth cells with the primary goal of enabling uncompressed soil in spite of the hard surfacing and heavy traffic.

StrataCell™

StrataCell™ is a root-friendly sub-base system. The modules are made of recycled plastic, are easy to click together and designed to withstand vertical and horizontal pressures on more than 550 kPa. Also, it can contain up to 94 % mould. To secure the best possible growth conditions for the trees, the planting holes have also been established with our RootRain X2 - our watering- and venting system. This secures that the soil always has sufficient oxygen and that the trees are watered below the surface. This way, you can optimise the use of water and ensure that the entire root system gets enough water.

Make the most of surplus surface water with local rainwater harvesting
Flowerbeds are an ideal way of dealing with rainwater
The KerbCell™ system reduces the strain on the sewer system in the case of more intense rainfall
Green urban areas solve the challenges of more densely populated areas, and they improve quality of life for the people of the area.
