Alga for Art

Since many years ALGA contributes to the restoring and protection of the artistic and historical heritage in Italy and worldwide, applying updated and innovative technologies.
We can mention the following among the most significant applications on worldwide well known art masterpieces:
• Strengthening of the Pisa leaning tower. To improve the local resistance of the stones, overstressed due to the inclination of the tower, has been applied a circumferential prestressing in several locations, utilizing a stainless steel wire that is practically not visible, having the same colour of the stones. To enlarge the foundation has been applied a steel carpentry strengthened to the tower by strand pos-tensioned tendons.
• Seismic isolation by use of HDRB of important historical bronze statues like: the Riace Bronzes at the Reggio Calabria Museum, the Dancing Satyr of Mazara del Vallo (Sicily) and the statue of Germanicus at the National Museum of Perugia
• Strengthening of the Herat Minaret in Afghanistan. The strengthening has been performed applying a circumferential prestressing by strand pos-tensioned tendons.
• Strengthening of the Saint Peter Cathedral in the City of Vatican. This has been performed applying prestressing bars to connect the facade to the cathedral body.
• Improvement of the foundations of the Saint Marc bell tower in Venice (currently under execution). In this case will be used titanium prestressing bars to resist the highly corrosive environment conditions.

The fact that ALGA has been called to operate on such famous and unique art masterworks is an other prove of its great competence and reliability.
