Le système d’évacuation des eaux de la ville de Cahors - Divona : schéma théorique et approche par l’étude des liants architecturaux

The city of Cahors-Divona has an evolved sewage system. The topography of the land required an adaptation but all the discoveries made until today allow some reflections on the organization of this system, both on its form and its implementation. In this article, we wish to approach their study through the study of architectural binders, i.e. mortars made of a mixture of lime and sand, sometimes TCA. We will see that these mortars fossilize a lot of information allowing to restore the gestures and the technical choices made during the construction sites.
