| Résumé : |
Overall, more than 97 percent of the steel surfaces were completely free of corrosion, with only up to 3 percent of some specific areas showing traces of corrosion not greater than Ri3 (less than 1 percent), according to ISO 4629-3, "Binders for paints and varnishes - Determination of hydroxyl value - Part 3 : Rapid test."
This is testament to the superior protection that can be achieved by using UHP waterjetting together with a high-performance, damp surface-tolerant epoxy system for maintenance in an environmentally sensitive area. |

- Fig. 1 : The Luis I Bridge, completed in 1886, was to replace an existing adjacent suspension bridge and consists of complex ironworks with one main arch which spanning 172 m, was the longest in the world at the time
- Fig. 2 : A complex water-recycling system was developed that would enable the used water to be re-used for waterjetting or returned to the river as clean water. The system was based on a combination of mechanical separation through decantation and filtration, and a special activated carbon filter that absorbed any remaining contaminants
