Green cities.


Reservoirs from retention and drainage boxes, enabling the development of roots and the growth of trees.



More than half of the world's population lives in cities today. City dwellers are exposed to a number of environmental problems caused by climate change, such as thermal stress and air pollution. One of the key elements alleviating these problems is vegetation, especially trees. Trees produce oxygen, improve air quality, provide shade and reduce the effects of global warming. They contribute to the health and well-being of the people who work and live in cities. More and more cities recognize the importance of investing in the sustainable development of trees and are looking for possible solutions. Wavin Q-Bic Plus tanks for trees is a new proposal from Wavin, thanks to which greenery in cities can develop without any obstacles, without damaging the surface of the streets.

 

Greenery architects and city authorities realize how much good green can do in the city. On a daily basis, however, they find out that trees are sensitive and vulnerable to threats, incl. drought, which poses a risk of losing large expenditures on the creation, maintenance and care of the good condition of trees. Planting trees in a traditional way - directly next to roads or sidewalks without any additional solutions causes the trees to grow with difficulty, die or their roots grow upwards causing damage to the surface, e.g. bulging or cracking. So how do the Wavin Q-Bic Plus tree tanks work? In the place where the tree will be planted, an empty space is dug, in which plastic retention and drainage boxes are then placed. The tree should be planted in the center, anchored and the rest of the space filled with a special substrate. In addition to the ground, water and air are also crucial for the growth of a tree. They are delivered to the roots by spreading drainage pipes. The tank structure is limited by permeable outer walls on all sides, providing a protective structure for the tree's soil volume. The side walls have a dual function - on the one hand, they ensure no contact between the surrounding soil and the ground, on the other hand, they serve as a retaining wall between compacted and non-compacted soil, which allows the soil to be compacted around the tank in accordance with applicable standards. The structure of the tank ensures complete resistance to movement and soil above the tank, and the substrate inside the tank remains uncompressed. This creates not only an ideal environment for the tree to grow, but a solution to ensure that the surface around the tree stays in good condition without bulging or cracking due to the roots. The tanks can also be quickly installed and dismantled. If, for example, at a later stage it is necessary to lay cables or pipes in the ground, the tree container can be easily excavated and opened. This creates not only an ideal environment for the tree to grow, but a solution to ensure that the surface around the tree stays in good condition without bulging or cracking due to the roots. The tanks can also be quickly installed and dismantled. If, for example, at a later stage it is necessary to lay cables or pipes in the ground, the tree container can be easily excavated and opened. This creates not only an ideal environment for the tree to grow, but a solution to ensure that the surface around the tree stays in good condition without bulging or cracking due to the roots. The tanks can also be quickly installed and dismantled. If, for example, at a later stage it is necessary to lay cables or pipes in the ground, the tree container can be easily excavated and opened. Wavin Q-Bic Plus tanks for trees enable the planting and growth of trees in areas where it would not normally be possible, e.g. in areas with a large amount of paved surfaces or in areas with a substrate that prevents the natural development of trees.

 

Tanks for Wavin Q-Bic Plus trees in Hasselt, Belgium
For the first time, a solution in the form of Wavin Q-Bic Plus tree tanks was used in Belgium in the city of Hasselt, in the new district Quartier Bleu. Like many other cities, Hasselt also strives for as much greenery as possible within the city and the sustainable development of trees. Hence, the city decided on a new and "green" solution to the existing problem and used Wavin reservoirs for 86 newly planted trees. Wavin actively participated in the process of developing a solution, cooperating in this area with the contractor responsible for the work, including green architecture in Hasselt.
