Abstract

Moisture is one of the main decay factors affecting old buildings. The movement of moisture is often accompanied by the presence of water soluble salts which can impact the masonry in several ways. Present paper explores the differences in vapour permeability between salty and non-salty masonries, how salts impact both the moisture retention and free evaporation of moisture. It has been found that electrically charged salt ions hinder the free evaporation of moisture, contributing to the retention of moisture inside the masonry.
