Cracks, which could be classified according to their thickness as fissures or fractures, are serious problems in the construction industry that can negatively affect aesthetics, durability and, most importantly, the structural characteristics of a project. They can happen anywhere, but occur especially in walls, beams, columns, and slabs, and usually, are caused by strains not considered in the design.
Fractures are usually of lesser severity. In general, they appear more on the surface of the structure. They are narrow and elongated, with openings less than 0.5mm. Sometimes they are not even visible to the naked eye. Generally, they do not imply structural problems but can lead to more serious consequences. It is important to note if the fracture grows over time or remains stable, because it may be the first stage of a fissure.
If not looked after, the next stage or a fracture could lead to deeper openings of 0.5 to 1.5mm. They can be seen without difficulty and are much more dangerous than the fractures because the rupture of the structural element has already occurred and can affect the safety of the part.
