What is the consequence of using bricks with excessive moisture absorption?

Increased insulation effectiveness
Scalability for repairs
Structural damage over time
Enhanced aesthetic appeal

The correct answer is: Structural damage over time

Using bricks with excessive moisture absorption can lead to structural damage over time. When bricks absorb too much moisture, it can cause several issues within the masonry system. First, the expanding water within the bricks when it freezes can lead to cracking and spalling, which compromises the integrity of the structure. This degradation can affect not only the individual bricks but also the mortar joints and overall structural stability. Additionally, excessive moisture can lead to other problems such as efflorescence, which appears as white, powdery deposits on the surface of the brick and can further damage the masonry by attracting more moisture. Over time, these effects can lead to significant repair costs and potentially even structural failure if left unaddressed. Therefore, it is crucial to select bricks with appropriate moisture absorption rates to ensure the longevity and durability of the masonry work.
