Created in 2005 in Meyzieu in the Lyon region by four entrepreneurs who are experts in the field of pollution control, Soléo is today a group of more than forty employees specialising in pollution control and solutions for soil and groundwater treatment. The Soléo Group has 4 branches throughout France, which enable it to be as close as possible to its customers and the sites on which it operates. The Soléo group has a complete range of skills enabling it to use both traditional pollution control techniques and more innovative solutions to meet the various needs and situations encountered (on-site, in situ and/or off-site treatment, and also asbestos removal)
In 10 years and after more than 800 clean-up operations for its customers, Soléo is recognized as one of the leaders on the clean-up market thanks to its know-how and professionalism in all stages of the business (from engineering to the completion of works).
Soléo is also one of the first companies to have obtained LNE (Laboratoire National de métrologie et d’Essais) certification as an authorized service provider for the engineering and execution of rehabilitation work on polluted sites and soils.
