What is the primary purpose of weepholes in masonry construction?

The primary purpose of weepholes in masonry construction is to allow water drainage. Weepholes are small openings placed in the mortar joints or at the base of walls. They serve an essential function in managing water that may accumulate within the wall assembly. If water is not able to escape, it can lead to several issues, including mold growth, deterioration of the masonry materials, and potentially compromising the structural integrity of the building.

By providing a way for moisture to exit, weepholes help to maintain a dry environment within the wall, thus prolonging the lifespan of the masonry and ensuring the overall durability of the structure. This drainage is critical for preventing water-related damage, particularly in climates where precipitation is frequent. The placement and size of weepholes are designed to effectively manage any condensation or water intrusion that occurs within the wall system.
