Masonry Cavity Walls and Moisture Control

Masonry cavity walls use two wythes, or layers, with a hollow space between them. The outer and inner wythes are linked only by corrosion-resistant metal ties. This design helps manage water and improve wall performance.

When rainwater passes through the outer wythe, it moves down through the cav...

A masonry cavity wall consists of two wythes separated by a hollow space. The outer and inner wythes are connected using corrosion-resistant masonry ties for structural stability.

When water penetrates the outer wythe, it enters the cavity and is collected by a thin impervious membrane called flashing, which is installed at the cavity's b...
