Symptom of Stem Wall Failure: Rust Production
When the concrete becomes more acid, the rebar is at risk of developing rust and spreading all over the stem wall, as seen in this picture. The rust can even get visible from the outside, meaning the rebar is completely oxidized.

Damaged Concrete Removal
In most cases, after removing all the damaged concrete, the rebar gets visible. However, there is still work to get done since the probability of having to change the whole rebar is very high due to oxidation.

As shown in the image, the galvanized tie-down straps got removed and will shortly get replaced by polypropylene loops straps to hold the rebar and create a strong attachment between the walls the stem wall.
