Why Can Building Structures Crack? These Are the Common Causes!

Cracks in building structures are a serious problem that not only disrupts aesthetics, but can also endanger the strength and safety of the building. Cracks can appear in various parts, such as walls, floors, columns, and beams. To prevent further damage, it is important to understand the common causes of cracks in building structures.

Here are some of the main causal factors:

1. Poor Material Quality
The use of building materials that do not meet standards, such as low-quality cement, sand, reinforced concrete, or bricks, can weaken the structure. Materials that do not meet technical specifications tend to degrade more quickly and cause cracks.

2. Errors in the Construction Process
Improper construction processes, such as incorrectly proportioned concrete mixes, non-standard reinforcement installation, or incorrect casting times, can trigger cracks. These technical errors can reduce the binding power of materials to each other.

3. Land Movement
Buildings built on unstable land, such as former swampy land, uncompacted embankment, or earthquake-prone areas, have a higher risk of cracking due to land movement. Even extreme changes in dry and wet seasons can cause land shifts.

4. Excessive Load
Structures that bear a greater load than planned, either due to additional floor renovations or changes in the function of the room, can experience excessive pressure. This triggers cracks, especially in beams and columns.

5. Concrete Shrinkage
After casting, concrete experiences natural shrinkage during the drying process (curing). If this shrinkage is not properly calculated in the design or implementation of construction, hairline cracks will appear which have the potential to enlarge.

6. Extreme Weather Conditions
Exposure to extreme weather such as scorching heat, heavy rain, or sudden temperature changes can cause expansion and contraction in building materials, so that cracks will appear over time.

Use Quality Materials for More Durable Construction
One effective way to reduce the risk of cracks is to use quality materials from the start. PT Intisumber Bajasakti provides a variety of steel products and SNI standard building materials to support your project.
