Although mortars have utilised earth, both as an aggregate and a binder for thousands of years, little is understood as to how vernacular earth mortars are dependant on the types of soils that are found locally to the place in which that mortar is to be used.
The goal of this study was to firstly build a picture of the historical, geographical and physical elements that would have affected the materials used to create the mortar and then from onsite samples, look for correlation between these samples in order to make evidence based decisions to the suggestion of a suitable repair mortar.
