Signs of Advanced Rust in Stem Wall: Flaking Paint
Flaking paint is one of the most common and fort signs of stem wall failure. Most people blame the sunlight and the heat when it comes to flaking paint, but the actual cause is a little more complex than that. Paint starts to flake when the concrete gets overexposed to water, and it becomes more acidic, affecting all the components of the stem wall as a result.
Signs of Advanced Rust in Stem Wall: Horizontal Concrete Cracks
As shown in this photo, the symptoms of stem wall failure are more severe. There are horizontal concrete cracks all over the stem wall, and there is still flaking paint in the area.
Signs of Advanced Rust in Stem Wall: Vertical Concrete Cracks
There are also vertical concrete cracks in a stem wall. Generally, when vertical cracks mean that the tie-down straps are in trouble. The tie-down straps tend to get galvanized, putting at risk the stability of the walls with the rebar.
