Using Air Barriers in Masonry Walls
|
Water in masonry walls creates numerous problems: freeze-thaw fractures, cracks form, efflorescence appears, etc.
This articles explains how an air barrier system can help alleviate this problem.

Putting the Drain on Rain: Moisture Control
|
The two basic drainage walls are the cavity wall and the veneer wall. Each has a masonry outer wythe and is separated from a structural
backup by 2- to 4 1/2-inch air space. This article discussed these systems.

Is Flashing Dangerous Without a Drip?
|
This article focuses on flashings for shelf angles and at lintels. These two areas are similar in that, whether or not drips are required,
water must not be allowed to re-enter the wall below the flashing.

Wall Cavities: Design vs. Construction
|
One thing is for sure, buildings are never constructed exactly as they are designed. Tolerances, differences in workmanship, and unrealistic
expectations are all responsible for variations that exist between the actual design and completed construction. No masonry standards specifically regulate how much and which types of variation from design are
allowed within a cavity wall. But recognizing which variations are acceptable is the key to providing a cavity that functions properly.

Why Extending Flashing is Critical
|
Too often, drawings do not clearly indicate or note how to terminate the horizontal and vertical legs (or returns) of flashing. Project
drawings and specifications commonly conflict with each other. To ensure the proper installation of flashing, both the drawings and the project specifications must clearly indicate and explain how to treat the
horizontal and vertical ends.

Flashing Residential Brick Veneer
|
The most common masonry wall system in residential construction is brick veneer. All brick veneer walls are drainage walls. Their design
should be based on the premise that water is going to enter into the wall system. Therefore, to ensure the wall's successful performance, the wall design must incorporate a means for water egress.
|
|
Proper Drainage for Weep Holes
|
For a cavity wall to function properly, water that collects on flashing must be able to drain through weep holes to the exterior of the
building. If weep holes do not function properly, water collecting in the cavity can infiltrate to the building's interior.
