Salt efflorescence is a common issue in masonry, brick cladding, and concrete construction, where white, powdery salt deposits appear on the surface of bricks, mortar, stone, or concrete. It occurs when water-soluble salts present within the building materials or surrounding environment are dissolved by moisture. As the moisture moves to the surface and evaporates, it leaves behind visible salt deposits, known as efflorescence.

Salt efflorescence typically results from a combination of moisture ingress and the presence of naturally occurring salts, such as calcium sulfate, sodium sulfate, or potassium carbonate. Common causes include:

• Excess moisture from rain, construction water, or poor drainage

• Inadequate damp-proofing or waterproofing

• High salt content in bricks, mortar, concrete, or the surrounding soil

In the brick cladding and construction sector, salt efflorescence can affect:

• Brick slip cladding and traditional brickwork

• Cast stone features such as cills, copings, and lintels

• Precast concrete panels and architectural components

• Mortar joints and pointing

While salt efflorescence is primarily a cosmetic issue, persistent moisture can indicate underlying problems with drainage, waterproofing, or material selection. Removal is usually straightforward using dry brushing, specialist efflorescence removers, or allowing natural weathering to clear the deposits over time.

Preventing salt efflorescence involves implementing good building practices, including proper moisture management, breathable sealers, damp-proof membranes, and ensuring materials are stored correctly to avoid moisture absorption before installation.
