A reinforced concrete bridge was retrofitted. As the intermediate support on the underside of the slab had to be removed, the static system changed and thus required a flexural strengthening of the slab. For this purpose, the concrete surface was hydromechanically roughened, memory-steel re-bars were installed and activated, and finally, covered with sprayed mortar (Sika MonoTop®-422 PCC) The system allowed to generate prestressing easily and reinforcing the structure efficiently without the need for extensive equipment.
