Diegem De Lediaan

Diegem 'De Lediaan', A green environment for every Diegem resident.

A former quarry and then landfill was left abandoned for over 40 years and will now be given a new residential destination with a large public park. With the remediation and redevelopment of the former Desmedt site, we present ourselves as a pioneer in upgrading landfills and in their sustainable integration within the environment.

The former Desmedt site used to be a quarry for the typical Lediaan sandstone. This high-quality stone was used for the construction of churches and palaces in Brabant.  Today, this site fits within the definition of a brownfield: after the sandstone extraction activities stopped in 1960, the site was used as a landfill for construction rubble until 1977, after which it was abandoned. After acquiring the site, we began its sustainable upgrading to a large publicly accessible park with space for ground-level housing, studios, city apartments, park apartments and penthouses.

“For the former landfill in Diegem, we have examined and assessed the potential of a possible reclamation. The material that has been dumped here over the years mainly consists of construction rubble and should therefore be easy to sieve. Where possible, the sorted rubble will be used as foundation material for roads and buildings. We will not only treat the waste substances found in the soil but we will re-use both the historically dumped construction rubble and the site itself. As such, we fully meet the circular ‘Waste to Land’ and ‘Waste to Materials’ principles.”
