Air & Moisture Control

Proper moisture control in masonry is critical for the longevity, durability, and structural integrity of a building. Without effective moisture management, water can penetrate masonry walls, leading to problems such as efflorescence, mold growth, freeze-thaw damage, and corrosion of embedded metals. These issues can compromise not only the aesthetics but also the safety and performance of the structure.

To ensure proper moisture control, features like flashings, weep holes, vapor barriers, and sealants must be correctly designed and installed. Together, these elements direct water away from the building, protect internal components, and maintain thermal efficiency. Invest in proper moisture control for your masonry today to safeguard your structure for years to come.
