Symptom of Stem Wall Failure: Flaking Paint
In many stem wall failure cases flaking paint might be an early sign of rebar oxidation.
Symptom of Stem Wall Failure: Horizontal Concrete crack
When the stem wall looks like this, it means the concrete got too exposed to moisture, and the PH of the concrete change. When the PH changes, the concrete becomes more acid affecting the rebar as a result.
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.
Symptom of Stem Wall Failure: Vertical Concrete Cracks
When there are vertical concrete cracks over the stem wall, it means there are galvanized tide-down. When this occurs, the tie-down straps will need to get replaced along with the rebar.
Symptom of Stem Wall Failure: Spall Concrete
Spalling concrete is one of the last symptoms of stem wall failure, but it is the most noticeable. When this happens, it's most likely that all the concrete material is about to fall off the stem wall.
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.
Tie-down Straps Removal
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.
