The white staining visible on the concrete is a common occurrence known as efflorescence.
- Efflorescence is a crystalline deposit of salts that forms on the surface of concrete.
- It occurs when water moves through the concrete and brings dissolved salts to the surface, where the water evaporates and leaves the salt behind.
- The process involves a chemical reaction between the water, acid, inorganic salts, and minerals already present in the concrete, such as calcium hydroxide.
- It is a cosmetic issue and generally does not affect the structural integrity of the concrete.
