Preventing Moisture Penetration in Architectural Masonry Walls

Concrete masonry from Abbot Building RestorationThe irregular surface of architectural concrete masonry units one of the key features to its aesthetic appeal. However, this rough exterior makes it more difficult for the top cap to conform to the surface and create a watertight seal, which could put the building at risk for damage caused by water penetration.

One of the main tactics you can use to prevent moisture penetration into the core spaces in the concrete block is to use a flexible and self-adhering material underneath the metal top cap. Another precaution is the use of a standard concrete masonry unit for the top course in place of the architectural unit. Utilizing standard concrete in the top course area makes it easier for the cap to adhere to the surface, and create a watertight seal.

In addition, it is prudent to detail a drip edge on the top cap. This helps to direct water away from the wall surface, and further prevent moisture penetration from entering the building’s core structure. Be sure to also include proper laps on both the cap and flashing material to serve as an added precaution against unwanted damage.
