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.
wall x rust
Case1.
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.
Leakage from cracks
Case2.
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.
bare rebar
Case3.
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.
