that crack,
Is it okay if I leave you alone?

The cause of the crack is ​, drying shrinkage of concrete, cement hydration heat during casting, environmental factors, earthquakes, deterioration, etc. ​

As it deteriorates over time, cracks spread to the inside, leading to water leakage, deterioration of internal reinforcing bars, and deterioration of the entire frame.

​ Possible causes:

If rust is forming along the cracks, water intrusion through the cracks may be causing the rebar to rust. Doing so may cause an explosion.

​ Possible causes:

Rainwater that enters through cracks looks for an exit like a living creature. Water may leak from unexpected places through cracks that have spread inside.

​Also, even if the wall looks dirty, it may have leaks underneath, so be careful.

​ Possible causes:

Due to earthquakes and deterioration, rebar that should have crumbled and was originally buried in the concrete may come to the surface and rust.

​Since the reinforcing bars that correspond to human bones are rusting, it can be said that the deterioration has progressed considerably.
