“…In an effort to maximize their service life performance, the degradation patterns of stone claddings are consequently the subject of extensive research [34,35]. In the design stage of exterior stone claddings, factors such as the exterior envelope geometry and the exposure conditions are given considerable emphasis [36]. Reliable models of the degradation of stone claddings along the service life are required for the optimization of the maintenance and service life expenses of the external stone cladding [37].…”

The attractiveness and durability of stone claddings make them a common exterior finish. However, comparative research of the performance of long-lasting “dry fixed” stone claddings and those made using the “wet fixed” method has not yet been carried out. The objectives of this study are to (1) characterize the deterioration patterns of exterior dry- and wet-fixed stone claddings exposed to normal and marine environments; (2) evaluate the life expectancy limiting coefficient (modifying factors), and (3) quantify the influence of a marine environment on both cladding methods. The research methods integrate laboratory tests with the field survey and probabilistic service life prediction methods. The results of laboratory tests indicate that the compliance of the stone with the requirements of the standard does not assure the durability of the stone when used as an exterior cladding material in a marine environment. The findings of the probabilistic methods show that, in both normal and marine environment service conditions, the fixing method has a significant impact on the rate of the stone deterioration process and the long-term durability of dry-fixed stone claddings.

“…This research method, called ex post facto, which literally means 'after the fact' or 'retrospectively', refers to those studies that investigate possible cause-and-effect relationships by examining the elements under analysis in real situations and searching back in time for plausible causal factors [21]. This course of action to assess the durability of building components was conducted in several studies [22][23][24][25][26][27][28].…”

Now more than ever, the construction sector is aiming to adopt more sustainable solutions. To achieve this purpose, more durable solutions must be adopted, making rational decisions at the design and maintenance stages regarding the conditions of environmental exposure and use. In this sense, knowledge regarding the service life of building components is crucial. This knowledge should not be a general concept, or a standard value, and adapting practices from one country to another is extremely challenging. In this sense, this study analyses the service life of natural stone claddings. We adopt a methodology initially proposed for Lisbon (Portugal), intending to evaluate its applicability to other geographical contexts, in order to perform a more reliable service life prediction of stone claddings located in Tehran (Iran). An estimated service life of 65 years was obtained for a sample of 162 stone claddings directly adhered to the substrate, located in Tehran, which were analysed by in situ inspections. The impact of different conditions (e.g., type of stone and environmental exposure conditions) on the service life of stone claddings in Tehran was quantified, which revealed that the exposure to environmental agents, such as wind, rain and pollutants, is the main cause of degradation of the natural stone claddings.
