What is the function of a weep screed in construction?

The function of a weep screed in construction is to prevent moisture from entering the structure. Weep screeds are typically installed at the bottom of exterior wall systems, especially in stucco applications, and they allow for drainage of any moisture that may accumulate behind the cladding. By facilitating the drainage of water, they help to protect the building envelope from potential damage caused by moisture intrusion, such as mold growth, wood rot, and deterioration of structural components.

This moisture management capability is critical in maintaining the longevity and integrity of the building. The proper installation of weep screeds contributes to effective water management by providing an unobstructed path for water to escape, thereby enhancing the overall waterproofing strategy of the structure.
