We offer technical services to our clients in the following industrial sectors:

  • Chemical fertilizers
  • Pharmaceutical

  • Buildings


Driven by our unrivalled capacity to mobilize quickly, our technical contribution is notable for its focus on rapidly converging towards the long-term success of our solutions. 


Our approach consists in attentively listening to our clients and to form a team with them up until the project’s very end: we insist on being present during the start-up of the installations we have designed.


We plan carefully in order to rationalize and optimize all of our activities. Right from the start of a project, we include all representatives of all disciplines which will impact design, including construction, technical advisors, health, safety and environment.
