What is known as efflorescence in the context of materials?

Efflorescence refers to the accumulation of dissolved salts that occurs when water migrates through a porous material, such as concrete or masonry. As the water evaporates from the surface, it leaves behind the salts that were dissolved in it, resulting in a white, powdery residue. This phenomenon often occurs in areas subject to moisture or high humidity, and it can be indicative of underlying water issues, such as leaks or poor drainage.

Understanding efflorescence is critical in the context of commercial drying and restoration because it can signal moisture intrusion and help professionals identify areas that may require further investigation or remediation. Recognizing the presence of efflorescence can assist in diagnosing moisture-related problems and implementing effective drying strategies to prevent further damage to the building materials.
