Resumen Se presenta en este trabajo un resumen de los resultados obtenidos en los ultimos anos en la caracterizacion de distintas estructuras de cimentacion mediante georradar, metodologia no invasiva que con la combinacion de antenas de distintas frecuencias permite conocer el tipo de cimentacion superficial (zapata, losa), sus dimensiones en planta y en profundidad, asi como los niveles de armadura interna existentes. En el caso de las cimentaciones profundas su aplicabilidad es mas limitada, pero en determinadas condiciones, puede suministrar los parametros geometricos principales. La informacion asi obtenida permite abordar los proyectos de rehabilitacion con una mayor seguridad y economia de recursos, al permitir conocer las geometrias de los elementos de cimentacion y su variacion, sin necesidad de acceder al subsuelo de forma directa o al menos para reducir la caracterizacion directa o dotar a dichos resultados de representatividad Abstract This paper presents a summary of the results obtained in recent years in the characterization of different foundation structures by means of georadar, a non-invasive methodology that with the combination of antennas of different frequencies allows to know the type of surface foundation (zapata, slab) , its dimensions in plan and in depth, as well as the existing internal reinforcement levels. In the case of deep foundations, its applicability is more limited, but under certain conditions, it can supply the main geometric parameters. The information thus obtained allows us to address the rehabilitation projects with greater security and economy of resources, by allowing to know the geometries of the foundation elements and their variation, without the need to access the subsoil directly or at least to reduce the direct characterization or endowing said results with representativeness.
