Efflorescence is a crystalline deposit of salts that form on brick, concrete and other building surfaces. In this blog, foundation repair specialist Rapid Dri discusses how efflorescence affects building exteriors and how it can be prevented.
What Causes Efflorescence?
Efflorescence appears as a white or gray deposit that gets left behind when water evaporates from building surfaces. It sometimes appears as a powdery substance that trickles down to the floor. Efflorescence happens due to water-soluble salts in rainwater and snow, as well as in condensation and groundwater. When left on a porous surface, the water evaporates and leaves salt on the surface, which forms a crystalline substance. Sometimes efflorescence occurs during remodeling or home construction. Careless builders tend to leave masonry units uncovered overnight, which absorbs moisture from the soil and rain.
While efflorescence doesn’t pose health risks, it can mar your home or commercial property’s exterior. It can also make existing structural damage worse, so taking action as soon as you see it can help minimize further damage.
Removal and Prevention
In addition to our services as a foundation repair contractor, we at Rapid Dri provide efflorescence removal services. If it can’t be removed using a mild soap or vinegar wash, we offer several methods for removing efflorescence, depending on its severity: powerwashing, sandblasting, chemical cleaning, or installing new grout, sealant, or joints.
Prevention is, of course, the ideal solution. Large, porous surfaces can be coated with hydrophobic sealant, which also helps improve the building’s waterproofing. Paying attention to the placement and condition of gutters, downspouts, and water delivery systems such as water sprinklers can help reduce the amount of moisture that gets onto the exterior surface. Preventive practices such as regular cleaning and inspection, covering materials and equipment when not in use, and using building materials optimized for waterproofing will also help reduce the chances of efflorescence forming on your property’s exterior.
