Where are weepholes typically placed in masonry walls?

Weepholes are typically placed at the base of the wall, which allows for proper drainage of any moisture that accumulates within the masonry. The purpose of weepholes is to prevent water from building up inside the wall, which can lead to damage and deterioration of the masonry materials. By strategically locating them at the base, any trapped moisture can easily escape, reducing the risk of water-related issues.

Placing weepholes in the corner joint, at the head joint, or at the top joint would not be effective for drainage purposes. The corner joint is not a low point for water to exit, while situating weepholes at the head joint or top joint could potentially lead to water pooling within the wall rather than facilitating drainage. Thus, the design principle behind masonry construction emphasizes weepholes' placement at the base of the wall to maintain structural integrity and longevity.
