Weep Hole

Definition

A Weep Hole is a small opening designed to permit drainage of water that accumulates inside a building component.

Purpose

The purpose of a weep hole is to allow trapped water to escape from within building components, such as walls or window frames, preventing moisture buildup, mold growth, and structural damage.

Examples of Use

• Brick Walls: Weep holes in masonry walls allow water to drain out from behind the bricks.
• Window Frames: Weep holes in the bottom of window frames prevent water accumulation and potential rot.
• Retaining Walls: Weep holes help relieve hydrostatic pressure by allowing water to escape from behind the wall.

Related Terms

• Drainage: The system or process by which water is removed from an area or structure.
• Ventilation: The provision of fresh air to a space, which can also help control moisture.
• Moisture Barrier: A material used to prevent moisture from penetrating a structure.

Notes

Proper placement and maintenance of weep holes are essential for their effectiveness. Blocked or improperly located weep holes can lead to water damage and structural issues.
