Cracks and fissures: Why they occur

Cracks and fissures are uncontrolled longitudinal openings that occur in roofs and walls of houses and façades. While the cracks only affect the coating of the structure, the fissures usually affect the entire area and involve further investigation into the causes that have led to it.

The causes of cracks and fissures can be very varied and involve different agents. In the case of surface cracks in walls and façades, changes in temperature, humidity or the action of atmospheric agents may have been the cause, such as rain, wind or environmental pollution.

In the case that the cracks and fissures have been produced by the effect of water or moisture, it is very important to assess the origin of the moisture, where it is located and how it may have affected the degradation of the structure.

Cracks can be an easy to treat, but it should also be taken into account that there may be a symptom that indicates a more serious problem and which requires more intervention, especially in the case of building façades or major cracks in interior walls or ceilings.

However, the causes of cracks in walls and ceilings may be the result of having applied a paint or plaster that is not suitable for the surface or its resistance to external agents. Rapid drying of the plaster can also cause cracks to appear because the coating components have not penetrated the surface.

On many other occasions, the appearance of these openings is due to deterioration caused by the passage of time and the natural settlement of the foundation which can cause cracks to appear in walls.
