Special works

Our special works activities group together our infrastructure repair, reinforcement and protection works and roads and utility networks (Reunion Island).

We reinforce aging infrastructures to make them more sustainable. Maintenance and repair of structures require expertise in construction chemicals and techniques and methods that we master.

We treat all pathologies of structures, mainly civil engineering works (deck protection, bridge repair, stack reinforcement on steelworks sites) and also building construction with dechlorination of concretes and decarbonation.

Offers et solutions

Concrete structures do not last forever but we can intervene to reinforce your infrastructures and extend their service life. 

We work to assist you as soon as the first symptoms appear. Our challenge is to adapt to your time, functional and budgetary constraints in order to transform the cost of the work into a profitable repair project with high added value. 

We aim to improve your return on investments in the medium and long term by implementing proven optimization techniques in restoration/construction. 

  • Diagnosis and dimensioning
  • Optimization for constrained interventions (cost...)
  • Methods (phasing, choice of equipment...)
  • Structural repairs
