Apartment Building, Palaio Psychiko, Athens

Apartment Building, Palaio Psychiko, Athens

The Project

Existing 1980’s building made of exposed concrete in Palaio Psychiko, Athens, the work of architect Jason Rizos. It consists of a limited basement, ground floor, 3 floors and an attic. The 36 pillars of the Pilotis were damaged by the rising soil moisture, spalling of the concrete cover and corrosion of the reinforcement were detected.


Measurements were made and the reduced strength of the concrete of these columns was confirmed. It was urgently needed to repair and strengthen them, to avoid the risk of failure under static or seismic loads. It was decided to encase them with sheet steel, with additional transverse reinforcement on the long sides, so that they act as confined composite columns, with high compressive strength and shear strength. The dimensions of the columns increased slightly, by about 3 cm, and the appearance remained the same by applying a special color, as that of the exposed concrete.


In the case of columns that are not accessible at the circumference, the steel sheet casing was replaced by composite construction with steel profiles.


The interventions were completed in the least two months with economy and absolute security, without the slightest annoyance to the residents, exclusively at Pilotis level. The aesthetics of the building was not affected at all.
