When it comes to maintaining the durability of brick masonry wall systems, moisture control is perhaps the most crucial design consideration. Unwanted moisture can cause masonry to experience dimensional changes, metals to corrode, and insulation to lose its effectiveness. Moisture can deteriorate interior finishes and lead to the appearance of efflorescence on exterior surfaces. Freezing and thawing from unwanted moisture can cause cracking, crazing, spalling, and deterioration over time. Water penetration also provides the moisture that mold needs to grow on susceptible wall elements.
