Which of the following is a drawback of masonry construction?

The long-term deterioration of mortar joints is a recognized drawback of masonry construction. Over time, the mortar that binds the masonry units can wear down due to various factors such as weathering, moisture infiltration, and freeze-thaw cycles. This deterioration can compromise the structural integrity of the masonry wall and may lead to issues such as water leaks, pest infiltration, and reduced overall stability of the building.

The long-term wear and tear of mortar joints requires ongoing maintenance and repair which can be labor-intensive and costly. It is critical for architects, builders, and maintenance personnel to consider this factor when selecting masonry as a building option, assessing the necessity for routine inspections and repairs to ensure the longevity and safety of the structure.

This decision involves understanding the environmental conditions the masonry will be subjected to, ensuring that appropriate materials and methods are employed to minimize deterioration and maximize the lifespan of the joints.
