In the Tacna region, buildings close to the sea often present pathologies in the concrete elements. These pathologies over time generate the development of the deterioration of the same concrete affecting the durability and service life of the buildings. The research aims to provide technical expertise in the stages of the start, planning and execution of buildings considering the vulnerability linked to a marine environment; by evaluating the mechanical, physical and chemical properties of concrete, diagnosing pathologies and concluding with a repair proposal. The research site corresponds to the Municipal Recreation Complex "Los Humedales de Ite", considering that it is exposed to a marine environment and a distance to the sea less than 2 km. Preliminary and detailed inspection was used for the development of research. Preliminary inspection identified exposure conditions (weather char...
