Electric Hydrofraise® to reduce fuel-oil consumption 

The Soletanche Bachy’s Group Technical Department presented the electric Hydrofraise® in the “Sobriety and decarbonisation of machinery” category. This innovation reduces one of our main sources of fuel-oil consumption, which alone is responsible for 90% of our direct CO2 emissions. By powering the machines directly from the electricity network, noise pollution is also reduced by three quarters. 

The circular wall without reinforcement – the diaphragm wall with sustainable credentials 

In the “Worksite Organisation and Logistics” category, the Soletanche Bachy France design office submitted the diaphragm wall with no reinforcement from the L15 Grand Paris Express worksite, which reduces the quantities of steel and concrete needed. This eco-design is the result of collective work. It was not only supported by the Horizon consortium’s partner, but was also validated by the project management, which welcomed this environmental variant. 

Soletanche Bachy is very proud of these innovations, which provide practical solutions to meet the environmental challenges facing us, and which also enable us to meet the needs of our customers’ projects. 

Congratulations to these teams for their nomination for the 2022 Public Works Awards, whose engagement and involvement are fully in line with Soletanche Bachy’s environmental ambitions.
