The repair process, which replaces damaged mortar joints between bricks is commonly known as tuckpointing. The procedure involves removing any decaying mortar and re-placing it to reseal the joints. Bricks can last up to 100 years, however the mortar between them may need restoration after 20-25 years. What causes mortar deterioration? There are many factors that cause mortar damage. Some of them may be a result of over-painting of brick facades with oil paints. However most damage is caused by weather conditions and external pollution. Sulfur compounds, dust and other pollutants from the atmosphere and a complex series of chemical reactions occurring in the near-surface layer of the bricks and in the mortar are the main reason dark deposits form on brick elevations. Deterioration of the mortar weakens the whole construction. Mortar degradation can lead to further damage of the bricks, as well as accumulation of moisture in the walls behind the bricks. It is important to prevent damages and fix existing issues as soon as possible. Tuckpointing isn’t a difficult technique, however there’s many things that can be done wrong, which would reflect on the appearance of the wall after completion. Tuckpointing should be done precisely, that’s why it’s best if it’s performed by an experienced masonry company like Prime Masonry Contractors Chicago.
