Proserve’s pile jacket system was used to provide 100 mm thick insitu concrete encasement to 29 N° 2 m diameter reinforced concrete bridge piers, filling cracks which had developed over the lifetime of the structure, and protecting against further damage to the piers from cracking and corrosion of the existing reinforcement.

The pile repairs were undertaken by contractor Domarcons as part of wider refurbishment works on the European Route E81 at Călimăneşti, Vâlcea. A 6 m encasement length was undertaken on all piles. The piles were accessed on pontoon working platforms via a truck mounted underbridge inspection unit, for mobile working under the bridge with live traffic overhead. The system was installed by divers, assisted by operatives on the working platforms.
