It is a hotel complex built around 1975, in a beautiful bay near Ermioni region at the prefecture of Argolis.
It consists of a complex of three large reinforced concrete buildings – with no shear walls – with a basement, ground floor and 4 floors, and – in addition – scattered suites, built amphitheatrically on the hillside.
In front of the complex lies the hotel’s large swimming pool, just a few meters from the sea.
The aggressive environment, due to its proximity to the sea, had a large impact on the reinforced concrete load-bearing skeleton, causing “spalling” of concrete and corrosion of reinforcement bars.
The columns of the ground floor and the basement had suffered “compressive-shear” “failure” due to differential subsidence of the foundations, possibly due to the water leakage of the large pool.
Around 2002, it was decided to address the above problems, with temporary measures, to prevent the collapse of the building.
The columns were “wrapped up” with steel-sheet jackets and a high strength mortar was inserted into the gap, making them resistant to compressive and shear loads.
No “earthquake-proof” strengthening of the building was asked, nor was it an intervention to address the damaging cause radically.
