There are several possible reasons why bricks on a building may bulge out:
1. Poor construction practices: If the bricks were not properly installed or the mortar was not mixed correctly, it can lead to bulging over time.
2. Moisture damage: Water infiltration can cause the bricks to expand and contract, leading to bulging. This can be caused by leaking gutters, downspouts, or flashing, as well as poor drainage around the building.
3. Foundation issues: If the building's foundation is not properly constructed or is damaged, it can cause the bricks to shift and bulge.
4. Thermal expansion: Changes in temperature can cause the bricks to expand and contract, leading to bulging if the building was not designed to accommodate these changes.
5. Structural issues: If the building is not properly supported or if there are structural issues, it can cause the bricks to bulge out.
It is important to address the underlying cause of the bulging bricks to prevent further damage to the building. Consulting with a structural engineer or building professional is recommended to determine the best course of action.

- Moisture: When water seeps into bricks and freezes, it expands and can cause the bricks to bulge outward. This is especially common in areas with cold winters. - Efflorescence: This is the formation of white or gray crystals on the surface of bricks. These crystals are caused by the evaporation of water that contains dissolved salts. Efflorescence can weaken the bricks and make them more susceptible to bulging. - Rusting: If bricks contain metal reinforcement, such as steel rods, the metal can rust and expand. This can cause the bricks to bulge outward. - Thermal stress: When bricks are exposed to extreme heat, they can expand and bulge outward. This is especially common in areas with hot summers. - Structural defects: If the foundation of a building is not strong enough to support the weight of the bricks, the bricks can bulge outward. This can also happen if the bricks are not properly mortared together.
