Coberturas sostenibles en excavaciones arqueológicas. Metodología de aplicación al caso de mosaicos en el Conjunto Arqueológico de Itálica (Santiponce, Sevilla)

Abstract

One of the challenges of the archaeological work is to prevent or reduce the effects of the "excavation trauma", where the accelerated changes of hygrothermal conditions together with the effect of solar radiation, alter the equilibrium conditions of the buried object. This leads to the need for a coverage during excavation of archaeological sites which is most often performed by fixed or removable systems that come from the productive or industrial world. They have high ecological footprint and limited impact, and ensure, mostly, only shady situations. But we understand that it is possible to provide a global solution from architecture to the numerous requirements of the excavated object, such as: covering systems with minimal supports, light covers highly adaptable to excavation changes, limited budget, or the control of hygrothermal conditions of the covered space through clean procedures that minimize environmental impact.
