Signs of Advanced Rust in Stem Wall: Concrete Cracks
As shown in the picture, there is a long horizontal concrete crack on the stem wall, which most of the time means the problem initiated in the rebar.
causes of Rust Production
Rebar starts to decompose when rust starts to grow. The problem is when concrete gets too much exposure to moisture, its PH changes, making the concrete more acid and ending up producing rust on the rebar.
Rebar Replacement
When the signs of rust production start getting visible, it means it is too late, and the whole rebar will need to get replaced. Before adding fresh cement, some anti-rust material needs to get added to the rebar as an extra precaution.
