Delivery of landscape substrates to Rotterdam

About the project

Client: Municipality of Rotterdam
Implementation period: 2017-2019

Den Ouden Groep supplies various types of soil improvers to the municipality of Rotterdam to ensure that nearly 600,000 trees and other green areas can remain in top shape.

Trees in Rotterdam are often planted in the middle of an urban area under conditions that are not ideal, such as paved surfaces, on the roofs of parking garages and on roof parks. These trees have little underground growing space. To keep these trees and green areas in top shape, it is necessary that tree or plant holes, lawns and flower boxes are filled with soil that has been formulated according to the correct specifications. A good stable product is of great importance for the medium term and the further future of the trees that have to grow in it. By applying high-quality soil improvers and substrates, Rotterdam ensures healthier and better quality trees and plants and therefore also a healthier living environment for its citizens.

This concerns more than 200,000 tons/year of tree sand, tree soil, tree granulate and flower box substrate. All produced under the RAG certificate.
