Hydrodemolition contractor ABC Construczioni SPA has used high-pressure water jets to remove damaged concrete as part of repairs and strengthening work on the Italian multi-span Rio Verde Viaduct.
Working for main viaduct repair contractor SEI-Idrojet, ABC carried out the concrete removal on one pier at a time. The repairs were performed from a purpose-built cradle and working platform that wrapped round all four sides of the piers.
The viaduct is one of the tallest in Europe and carries the busy dual two-lane A15/E33 Autostrada della Cisa over a steep sided valley in the municipality of Pontremoli.
The piers are 21 m long and 8.5 m wide at the base, tapering to 2.5 m wide at the apex.
