What are the rust colored stains on my wall?
Rust colored stains, especially on block or poured concrete walls, are a sign of acid damage. The soil outside your home is very acidic, and when the water leaks into your basement, it draws that acidity with it. Your wall acts as a filter, holding this acid back and allowing the filtered water into your basement. Acid damage can lead to lower wall deterioration. With an average of 50 tons resting on your foundation walls, the integrity of your walls must be maintained.
