Efflorescence may not be a term that you are familiar with, however, it is likely something you have seen before. The term efflorescence refers to the white stains and deposits that can frequently be found on brickwork, paving, concrete and masonry work.So what causes efflorescence?
There are three types of efflorescence on masonry work each caused by the presence of water moving through capillaries within masonry
Lime bloom has a superficial effect on masonry work. It appears as a white thin sections on the masonry as the result of water traveling through masonry. Fortunately this type of efflorescence typically disappears when exposed to weathering.
Lime weeping does not affect the durability of a structure, however, unlike lime bloom it is usually permanent. Lime weeping is most frequently seen in older masonry work where lime bloom has gone unchecked. As with lime bloom, lime weeping is a result of water moving from within masonry work
Crystallization of soluble salts is the least common type of efflorescence and it is the result of masonry work produced using seawater or on retaining walls. When this happens, deposits of soluble salts are found within the masonry work and as they crystallize within, they stress the concrete and brick work resulting in swelling.So what can you do about efflorescence? The best way to tackle efflorescence is to prevent it from occurring. Prevention of efflorescence is to prevent water from being able to travel through masonry work.

Above, we talked about the detriment of efflorescence and how you can prevent it from damaging your masonry work by having a professional treat and seal your pavers. Sealing pavers not only prevents efflorescence from marring their physical appearance and structural integrity, but it also gives then a cleaner appearance, prevents surface erosion and stabilizes the joint sand.
