What is efflorescence?
Quite simply, if you find efflorescence on your property, then you have a moisture problem which, if left untreated, will ultimately damage the structure of your building. Water infiltrates the block or concrete wall, dissolving the minerals within it. As water evaporates from the surface of the unit, the mineral deposits are left behind. As a result of this, efflorescence crystals start to grow.
Although often nothing more than a visual problem, if the efflorescence crystals grow inside the surface of the unit, spalling can occur. In this case, the surface of the structure will peel, pop out, or flake off as the salt pushes from the inside out, eventually causing the structure to crumble and deteriorate.
