What masonry defect does pointing specifically address?

Pointing specifically addresses defective mortar joints in masonry. This process involves applying new mortar to the joints of masonry units, which can become degraded over time due to weather exposure, movement, or other external conditions. When mortar joints deteriorate, they can lead to structural weaknesses and allow water infiltration, but pointing serves to restore the integrity of these joints, ensuring they effectively transfer loads and resist moisture.

By repairing or renewing the mortar, pointing helps improve the overall durability and longevity of the masonry structure. This maintenance technique directly targets the condition of the mortar itself, making it vital in preserving the quality of masonry work. While other issues like cracking, water infiltration, and spalling can also be related to joint integrity, pointing is specifically a remedy for the state of the mortar joints.
