In response to this problem, S&P Reinforcement France worked on the reinforcement of the structure using composite materials adapted to the future needs of the site: namely S&P C-Laminate and S&P C-Sheet.

Thanks to the solution, the original beams and floors could be retained, and reinforced with S&P C-Laminates bonded to the underside of the beams to counteract the bending moments, combined with S&P C-Sheet fabrics to deal with the shear forces. Slot applied S&P C-Laminates (Near Surface Mounted or NSM) embedded in the substrate, were used to negate the negative moments induced by the structural changes.
