Our work in Essonne (91)
Essonne (91) combines the Saclay plateau — a rapidly expanding science and tech hub — with vast residential suburbs south of the Orge valley. FDM ENERGIE works here on recent commercial buildings (flat roofs, waterproofing systems) as well as 1970s houses needing renovation.
Local context in Essonne
In Massy, Palaiseau and the Saclay plateau, most projects involve technical flat roofs with multilayer bituminous systems and vapour barriers. Around Évry-Courcouronnes and Corbeil-Essonnes, 1960s–1980s apartment blocks require waterproofing refurbishment. In the south (Étampes, Dourdan), traditional residential housing dominates with high demand for rigid fence replacement.
We support roof insulation projects with a clear technical file, transparent estimates and a 10-year warranty on covered works.
