GROUPE STANKIA is a recognized player, specializing in waterproofing, insulation, and the safety of flat roofs. With its intervention teams, GROUPE STANKIA handles more than 600 projects annually, exclusively for B2B clients.

GROUPE STANKIA is among the few waterproofing companies operating both in the nuclear market (including power plants and research centers), serviced by its subsidiary TEP ETANCHEITE, and in renovation markets for public and private environments through its subsidiary BATI ETANCHE ILE-DE-FRANCE. This latter provides a comprehensive service offering, ranging from complex construction work to the maintenance of particularly sensitive sites, such as various CEA (Commissariat à l’énergie Atomique) facilities and the RATP. Based near Paris, BATI ETANCHE ILE-DE-FRANCE achieved a turnover of approximately €8.5 m last year.

As of today, GROUPE STANKIA only runs its subsidiary TEP ETANCHEITE and intends to explore medium-term liquidity options for this company, which specializes in operations within the nuclear sector. TEP ETANCHEITE is experiencing significant growth, driven notably by major investment programs dedicated to the maintenance of nuclear power plants across the country.
