Flashing is so important in brick masonry because?

Flashing plays a critical role in brick masonry primarily because it addresses the issue of moisture management. Brick and mortar, while highly durable, can still be susceptible to water infiltration. If moisture penetrates the brickwork, it can lead to a variety of problems, including deterioration of the masonry, mold growth, and structural compromise over time.

The purpose of flashing is to direct water away from vulnerable areas, such as at joints or transitions in the building material. By effectively channeling water away from the wall system, flashing helps prevent the accumulation of moisture that could otherwise infiltrate and cause damage. This proactive approach to water management is essential for maintaining the integrity and longevity of brick structures.

While aesthetic appeal, installation time, and construction costs can be important considerations in masonry work, they do not address the functional necessity of moisture control that flashing provides. Therefore, the primary reason for using flashing in brick masonry is indeed its crucial role in managing moisture.
