A Guide to Basement Efflorescence, Louisville, Kentucky

From warm red-orange to contemporary gray, brick and concrete each offer a unique aesthetic appeal. However, they may accumulate a white film over time, which you cannot remove through normal cleaning techniques. This is known as efflorescence, and it's common on basement walls. To learn how this residue forms, and how basement waterproofing will prevent it from worsening, below is more information about it. 

What Is Efflorescence?

The pale splotches on your basement walls are an accumulation of mineral particles, which remain when moisture in the air evaporates. This forces the particles to cling to the brick or concrete and form a film that you cannot remove easily. Without prompt attention, efflorescence can turn into a thicker, three-dimensional layer of hair-like strands.

basement waterproofingWhile efflorescence isn’t dangerous, it indicates that there is a significant amount of moisture in your basement. This means that mold and mildew are more likely to grow in this space, and any items you store down there are at risk for damage. As the basement air rises, mold spores could travel through the rest of your house, decreasing the indoor air quality.

How Can You Prevent Moisture Problems That Lead to Efflorescence?

Efflorescence is common in basements because brick and concrete are porous materials that allow moisture to travel through them. Therefore, the best way to prevent these white deposits is to block water vapor from entering them entirely. 

Basement waterproofing companies will line the outside perimeter of the home with a sealant or membrane. This will prevent excess runoff and inherent moisture in the soil from permeating your basement walls. You may also want to have a professional inspection of the foundation, as cracks could be allowing water to enter your home. Finally, invest in a dehumidifier to extract moisture that is present in the basement air.
