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.
The main benefits you’ll receive by hiring professionals to tuckpoint your wall or chimney include:
The main advantage of tuckpointing is shielding your masonry structure from external weather conditions and moisture that penetrate the materials and cause corrosion. Tuckpointing is an effective way to prevent further deterioration by stopping the water from entering the wall. If poperly done, tuckpointing will extend the life of a wall, chimney and fireplace.
Tuckpointing recreates the original shape and condition of the bricks and mortar, which will make your wall or chimney look like new again.
You may avoid a costly rebuild of your structure that involves a complete tear-down and rebuilding the construction from scratch. Fixing existing damages is far more profitable than a full chimney or wall replacement.
