Concrete Repair - Spalling Concrete on Stem Wall in Phoenix, AZ

When the stem wall failure becomes visible, as in this photo, it might be too late, and most of the stem wall is already damaged. Spalling concrete on stem walls is more common than people might think. Spalling concrete happens when concrete changed its PH and becomes more acidic, affecting the rebar and the tie-down straps as a side effect by making them oxidized.
