The industrial process of manufacturing waterproofing membranes inevitably generates waste (machine start-up, change of production type, etc.). Axter has found a solution at the Courchelettes factory to reduce the environmental impact of its waste (rolls unfit for use) by giving it a second life… on our roads.

After several stages of crushing into granules, it is sold to a production unit that manufactures asphalt for roads. It is then added in very precise proportions to road products as bituminous binders and polymers.


  • To meet the construction industry’s environmental requirements (HQE approach, low energy buildings, HPE and THPE labels, etc.).
  • To address the environmental and health aspects of our products using Environmental Data Sheets (EDS) and Safety Data Sheets (SDS), in order to meet the 14 targets of the HQE approach.
