The structure known as Parador Ariston is located a few kilometers from the city of Mar del Plata,on the Atlantic coast of Argentina. It stands as an example of the rich architectural heritage of theregion. It was designed by the renowned modernist architect Marcel Breuer and built in 1948. Itstands out for being Breuer´s only work in Latin America. The structure consists of an elevated floorwith curved shapes that seen from above resembles a clover. The slab is made of reinforced concreteand is supported by four columns of the same material. Since built, it had different uses, havingfunctioned mainly as a gastronomic and recreational space. Since 1993 it has been abandoned andneglected. The structure is located at less than 100 m from the seashore, and so the progress ofcorrosive processes affecting the reinforcing steel of reinforced concrete should be evaluated.Corrosion in reinforced concrete compromises the integrity of a structure and the safety of peoplecirculating nearby. Cracking and delamination of concrete and reductions of diameter of thereinforcements. It also affects environment of the structure since detachments of material can occurare often observed. Structural compromise can be established by carrying out an in-depth diagnosisof the structure. The evaluation was carried out trying to minimize destructive interventions. Avisual survey was undertaken, including measurements of corrosion potential, degree ofcarbonation, cover thickness and diameter of reinforcements. The inspection showed no indicationsof corrosion processes endangering the integrity of the structure. Some sectors were identifiedwhere immediate attention was required to delay deterioration. Preventive measures andrepairments were recommended. This study is expected to contribute to expand the city´s heritage,recovering an emblematic building so that it can be visited and appreciated by locals and tourists
