The anti-seismic safety work on the building involved implementing a solution consisting of
PBO-Mesh 22-22 in PBO fibre and
MX-PBO Masonry, cementitious fibre-reinforced inorganic matrix, together with the
PBO-Joint connection system, consisting of PBO fibre connectors and
MX-JOINT inorganic matrix, designed for use with
Ruregold FRCM systems.
The work was divided into various phases, during the initial phase, the plaster was removed from the upper part of the bell turrets, after which the damaged and cracked parts of the four columns of each turret were repaired by “unstitching-restitching”, where the detached parts were removed, cleaned and washed, the mortar repaired using NHL 3.5 class M5 type hydraulic lime mortar, reusing the original stone segments where possible, and taking care to repair the anchorings.
Once strengthened, the columns of the turrets were wrapped in
PBO-Mesh 22-22 mesh, embedded in a coat of
MX-PBO Masonry mortar, and anchored using
PBO-Joint fibre connectors with
MX-JOINT inorganic matrix.
The
surface was then
finished with a specific, lime-based restoration mortar and a coat of colour in the same shade as the rest of the building.
