 This research examined the effectiveness of different mortar layers in protecting brick walls from moisture penetration under current and future climatic conditions. The results showed that the type of mortar used can significantly affect the amount of moisture that reaches the interior of the wall. Additionally, the distribution of rainfall events during a given storm event can have a significant impact on how much moisture reaches the interior of the wall.
