How is Water and Moisture Drained from a Masonry Wall?

Masonry Wall Drainage Overview

Effective drainage systems in masonry walls are fundamental to avoiding water damage and maintaining structural integrity. These systems manage and divert water away from walls, helping to keep interiors dry and prolonging the lifespan of the building materials.

Key Components of Masonry Wall Drainage Systems

Several elements work together to efficiently drain water and moisture from masonry walls:

• Through-Wall Flashing: Waterproof barriers installed within the wall to redirect moisture to the exterior. Positioned at different levels, often just above openings like windows and doors.
• Weep Holes: Openings or tubes placed at the base of the wall or just above windows to allow water to escape from behind the wall.
• Drainage Cavity: A gap between the masonry veneer and the backup wall where water can collect and drain away. Typically around 1-2 inches wide.
• Capillary Breaks: Materials such as sealants or flexible membranes that prevent water movement through tiny pores in the masonry components.
• Sealants and Mortar Joints: Properly applied sealants and well-maintained mortar joints prevent water ingress and maintain the structural integrity of the wall.
• Masonry Joint Recesses: Sometimes small recesses are left in vertical joints to aid moisture drainage and drying.
