Signs of Advanced Rust in Stem Wall
As you can see, the paint is flaking, and some concrete cracks are all over the stem wall. When concrete starts to get too much exposure to moisture, its PH turns acid and makes the rebar produce rust which will eventually make the concrete crack from the inside out.
Signs of Advanced Rust in Stem Wall
Sometimes the visible signs can appear even from the inside of the property. Rust production happens when there is an accelerated rust production.
Effects of Rust Production
Most of the time, when the stem wall failure signs are visible, it means it is time to replace the whole rebar. Usually, when the rebar is affected by rust the tide-down straps might need to get replaced too. The purpose of these changes and replacements is to make a strong connection between the rebar and the walls of the house.
