ALTEK® ECO²B is bitumen from direct distillation with activation, in blocks packed with a thermofused film. It is often used as a binder for bonding insulating materials under hot temperatures (cellular glass fiber) and waterproofing membranes, for insulation and waterproof treatment of industrial buildings’ roofs. After the bloc liquefaction in a regulated temperature kettle, the material is ready to use for bonding operations. Compared to oxidized bitumen use for the same bonding insulating properties, ALTEK® ECO²B brings higher performances such as enhanced adhesion characteristics and optimum creep resistance, better storage stability during summer weather, and better comfort for the installation teams.

The TotalEnergies Ecosolutions advantage

ALTEK® ECO²B was developed for an optimal application handling at a melting temperature 70°C lower than the one usually fixed for oxidized bitumen in standard conditions (temperature > 220°C and non-regulated temperature kettles). Moreover, the thermofused packaging film improves on-site waste management.

The Environmental Performance


  • Between 6%(1) and 27%(2) reduction in energy consumption on the whole life cycle and between 36%(1) and 58%(2) during the application phase
  • Between 13%(1) and 32%(2) reduction in greenhouse gases emissions on the whole life cycle and between 36%(1) and 58%(2) during the application phase
  • Reduction by a factor 14 of polycyclic aromatic hydrocarbons emissions during the application phase

(1) Standard practice with a non-regulated kettle

(2) Use of a regulated kettle
