Cracks in buildings can be defined as the separations or fissures that appear in structures, such as walls, columns, slabs, beams, etc, due to various stresses or weaknesses.
They can be classified as either structural or non-structural cracks, with structural cracks indicating potential safety hazards and non-structural cracks being primarily aesthetic or related to minor issues.

Reasons for the Cracks in Buildings
Cracks in the buildings can be caused by the following:
- Settlement and soil movement
- Structural Issues
- Material Related Issues
- Environmental Factors
- Other Factors
1. Settlement and Soil Movement
In its intended life and during the soil movement, buildings can settle and make cracks in the foundation, walls, columns, and floors.
Furthermore, due to changes in moisture, temperature, or other factors, the soil may expand and contract, causing cracks in the building.
2. Structural Issues
Structural issues, such as poor foundation design, can lead to cracks in the building. The structural members should be designed properly to ensure that the structure is safe and economical for its intended life.
Insufficient support from beams, columns, or other structural elements can cause cracks in the building. Furthermore, excessive weight or stress on the building can lead to cracks.
3. Materials-related issues
Here you see that concrete can shrink as it cures, leading to cracks in the building. Furthermore, defects in building materials, such as weak or porous concrete, can contribute to cracks. Corrosion of reinforcement steel or other metal components can also cause cracks.
4. Environmental Factors
Extreme temperature changes can cause building materials such as plaster and concrete to expand and contract, leading to cracks.
Excessive moisture can lead to cracks in buildings, especially in areas with high humidity or water tables.
Furthermore, Earthquakes can cause cracks in buildings due to ground shaking and soil movement.
5. Other factors leading to cracks
- Other factors, such as substandard construction methods or workmanship, can lead to cracks.
- Failure to maintain the building properly can contribute to cracks in the building, and
- And also, Buildings naturally deteriorate over time, leading to cracks.
Structural Cracks
As described above, Structural cracks in buildings are cracks that affect the structural integrity of the building, potentially compromising its stability and safety.
Reasons for Structural Cracks
These cracks can be caused by:
- Shifting or settling of the foundation can cause cracks in walls, columns, and floors.
- Poor soil conditions or soil erosion can lead to structural cracks. Structural engineers must check the stability of the soil by doing soil tests before designing the foundation of the structure.
- Excessive load on the structure can cause cracks. Proper design must be done to overcome the excessive load of the structure.
- Flaws in design or construction can lead to structural weaknesses and cracks. The design and construction should be free from any errors to ensure that the structure is safe from any structural cracks.
- Earthquakes, wildfires, floods, or other natural disasters can cause significant damage that leads to structural cracks.
Characteristics of Structural Cracks
The structural cracks always have the following characteristics:
- Structural cracks are often wider and deeper than non-structural cracks. Cracks in load-bearing walls, beams, or columns can be structural; furthermore, Cracks may follow a pattern, such as diagonal or horizontal, indicating structural issues.
Consequences of Structural Cracks
Untreated structural cracks can lead to further damage and deterioration. Also, repairing structural cracks can be expensive and time-consuming.
Importance of Addressing Structural Cracks
- Repairing structural cracks can prevent further damage and deterioration to the structure.
- Addressing structural cracks can help maintain the property’s value and integrity.
If you suspect structural cracks in your building, it’s essential to consult a qualified building expert for assessment and repair recommendations to avoid deaths and property loss.
Final Thought on Cracks
It is our responsibility as engineers to ensure that buildings are safe for human use in all environments.
Cracks can cause serious damage to buildings and cause them to collapse, resulting in deaths and property loss.
That’s all.
