What is the primary purpose of a weep hole in brick veneer construction?

The primary purpose of a weep hole in brick veneer construction is to allow water drainage and prevent moisture buildup. Weep holes are strategically placed openings that are incorporated into the bottom of masonry walls or brick veneer systems. Their design enables trapped water that has infiltrated the wall system, whether from rain, condensation, or other sources, to drain out. This drainage helps to mitigate the risk of moisture-related problems such as mold growth, deterioration of masonry materials, or damage to the building's interior. Proper function of weep holes is essential in maintaining the integrity of the structure, ensuring that moisture does not accumulate and cause long-term damage.

In contrast, while structural support, aesthetic enhancement, and noise reduction are important considerations in building design, they are not the primary functions of weep holes. Weep holes are specifically intended to manage water drainage, making them critical for the durability and performance of brick veneer constructions.
