How are weep holes formed in masonry construction?

Weep holes are formed in masonry construction by leaving gaps between bricks during the installation process. This method allows excess moisture that accumulates within the masonry wall to drain out, preventing water from pooling and damaging the structure. The gaps act as small openings that provide a path for water to escape, improving drainage and ventilation within the wall system.

This technique is vital for maintaining the integrity of masonry walls, especially in climates with significant precipitation. By ensuring that they are strategically placed, weep holes help manage moisture, thereby reducing the risk of mold growth, efflorescence, and structural damage caused by water infiltration.

Drilling holes in the bricks is not an effective or standard practice, as it could compromise the structural integrity of the masonry. Applying a weep hole membrane could be beneficial but does not address the formation of weep holes themselves. Adding a drainage pipe to the foundation relates more to broader drainage strategies rather than the specific creation of weep holes within the masonry.
