Weathered Joint

Definition

A Weathered Joint is a mortar joint finished in a sloping profile that tends to shed water to the outside of the wall.

Purpose

The purpose of a weathered joint is to direct water away from the wall surface, reducing the potential for water infiltration and damage to the masonry. This joint profile enhances the durability and weather resistance of masonry walls.

Examples of Use

• Brick Walls: Commonly used in exterior brickwork to improve water shedding.
• Stone Masonry: Applied in stone walls to enhance water resistance.
• Chimneys: Used in the construction of chimneys to prevent water from seeping into the masonry.

Related Terms

• Concave Joint: A mortar joint with a curved profile, also used for water shedding.
• Flush Joint: A mortar joint that is flush with the masonry surface.
• Raked Joint: A mortar joint where the mortar is recessed from the face of the masonry.

Notes

Weathered joints are an important detail in masonry construction for improving water management and prolonging the life of the structure. They should be properly tooled during construction.
