The Tertre des Roche development project in Vaux le Penil (Seine-et-Marne- 77) is taking shape. Opening to the public is scheduled for spring 2026. Creation of fertile soil on the final models After four months of bringing in inert soil from the local construction industry, ECT’s teams are now finalizing the site. The teams have now completed the modelling of the new layout and they are beginning to lay a fertile horizon. This step is essential to the renaturation of Tertre des Roches. No topsoil is being imported here. The fertile soil is created from selected silts from construction sites.
