Efflorescence

Efflorescence is a white crystalline or powdery, often fluffy/fuzzy deposit on the surface of masonry materials like concrete, brick, clay tile, etc. It's caused by water seeping through the wall/floor/object.

Efflorescence: A deposit or encrustation of soluble salts (generally white), that may form on the surface of stone, brick, concrete or mortar when moisture moves through the masonry materials and evaporates on the surface.

EFFLORESCENCE: An encrustation of soluble salts, commonly white, deposited on the surface of concrete, brick, mortar, stone or stucco; usually caused by free alkalies leached from concrete or mortar as moisture moves through it.

Efflorescence: Crystalline deposit appearing on cement or brick surfaces due to the evaporation of water containing soluble salts. The salts left behind on the wall surface have a crystal-like appearance.

Efflorescence is a fancy name for white, crystalline deposits that can appear on masonry or concrete. These deposits occur when moisture within the masonry rises to the surface, carrying minerals with it.

Efflorescence. Powdery residue coming out of stonework onto the painted surface.

Efflorescence (white powder stains) and musty odors are telltale signs of moisture problems. Basement remodeling traps invisible water vapor, causing mold and mildew. Most basements start leaking within 10 to 15 years.

Excessive impurities in mixing water not only may affect setting time and concrete strength, but also may cause efflorescence, staining, corrosion of reinforcement, volume instability, and reduced durability.

One issue that manufactured stone veneer faces is called efflorescence. Efflorescence is caused when moisture brings water-soluble salts to the surface of concrete and other masonry products.

Common problems of old interior brick and stone include spalling and efflorescence. Spalling occurs when water gets inside the brick or stone and pushes salt toward the outside, causing the brick face to peel, flake or crumble.

Efflorescence is a white powdery deposit formed when naturally occurring salt compounds are drawn to the surface of masonry by water seepage. When working with muriatic acid always wear rubber gloves and eye protection and have adequate ventilation.

efflorescenceA deposit or encrustation of soluble salts, generally
white and most commonly consisting of calcium sulfate, that may form on the
surface of stone, brick, concrete or mortar when moisture moves through and
evaporates on the masonry.

First clean the walls of efflorescence, mildew, peeling paint, etc. and seal all joints, cracks and holes with a waterproof sealant. This paint coating will not hold back water, but should help control dampness.

There are many surface problems that can happen to concrete; scaling, cracking, dusting, spalling (Figure 1), discoloration, popouts and efflorescence. When the surface layer of the concrete is coming off it is known as delamination.

You know, you see all this white chalky powder stuff on here, this is called efflorescence.

Any time water gets into a masonry wall you shorten the life of that wall from frost or just the normal breakdown of the concrete in water. Also the chance of efflorescence is increased with the added moisture.

But beyond that, learn to look at your basement like a detective and search for indirect things, such as: peeling paint on the walls (condensation will cause the paint to peel); white, powdery material on brick walls called efflorescence; ...
