Red Seal Bricklayer Practice Exam

Question: 1 / 400

What is a common issue caused by trapped moisture in brick walls?

Cracking and degradation

Trapped moisture in brick walls can lead to significant structural issues, most notably cracking and degradation. When moisture becomes trapped within the brick and mortar, it can freeze and expand in colder temperatures, creating pressure that leads to cracking. This not only compromises the aesthetic appearance of the wall but also its integrity and strength over time. Additionally, the presence of moisture can facilitate mold growth and deterioration of the materials, further exacerbating the problem. Addressing moisture management and ensuring proper drainage are essential to maintaining the durability and lifespan of brick structures. This focus showcases the importance of building practices that prevent moisture entrapment.
