Opening of a new ECT site in Essonne (91) Since February 23, 2026, the Val Saint-Germain – Les Houdoux site in Essonne has been open to inert soil deliveries. The site accepts K3 and K3+ inert soil, tracked by cubic meter or ton. Access to the site is regulated via the D27 and then the D132. Crossing Angervilliers is prohibited. Equipped with a weighbridge, the site guarantees accurate weighing, complete traceability of the soil, and simplified management of deliveries. This new ECT site offers a local solution for soil recovery that is secure and compliant with regulations. Consult site access

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.
