Understanding Efflorescence In Concrete: Causes, Prevention, And Solutions

Efflorescence is a common issue in concrete structures, often characterized by the appearance of white, powdery deposits on the surface. This phenomenon not only affects the aesthetics of concrete but can also indicate underlying moisture problems. In this blog, we will explore the meaning, causes, prevention methods, and solutions for efflorescence in concrete, ensuring a comprehensive understanding of this issue.

What Is Efflorescence In Concrete?
Efflorescence in concrete refers to the white, powdery substance that appears on the surface of concrete structures. This deposit is primarily composed of salts that are carried to the surface by water migrating through the concrete.


Efflorescence in concrete is the process by which soluble salts and other water-dispersible materials come to the surface of concrete and form a whitish deposit as the water evaporates.

Efflorescence In Concrete Meaning
The term “efflorescence” is derived from the Latin word “efflorescere,” meaning “to flower out.” In the context of concrete, it describes the crystalline deposit of salts that forms on the surface, usually due to water movement within the concrete.
