Self-cleaning walls


Did you know that there are products that consolidate the rock and prevent water from penetrating it? Others make it possible for the stone to clean itself by taking advantage of light or rain. It is the contribution of the Molecular Sieves Research Group from the University of Cadiz. These new materials are aimed at preserving historic buildings against contaminants such as graffiti. They have already been successfully tested in some archaeological sites, among them Baelo Claudia (Tarifa, Cadiz). Source: HdL
