Abstract

Brick masonry walls in Cultural Heritage buildings often have problems caused by rising damp. One solution is to coat thewalls with repair mortars, including macroporous mortars. Their function is to ensure that the wall has a lower moisturecontent than without the coating to reduce deterioration, prevent efflorescence and prevent damp stains. This article presentsthe conclusions reached on the behaviour of macroporous mortars with regard to water absorption by capillary action and thedrying process, by means of laboratory tests carried out on brick and mortar specimens of a similar composition to the oldwalls, coated with macroporous mortars. From the study it can be concluded that these coatings can help to maintain a lowerlevel of humidity in the masonry before reaching saturation.
