Efflorescence Nicolock Cambridge Pavers

About Concrete Products and paving stone such as Nicolock, Cambridge, Techo-Bloc and Unilock

Efflorescence White Powder on Nicolock & Cambridge Pavers, concrete products are produced by combining sand, cement, water, and different color pigments.They are then molded into shapes that are used for hardscapes installation such as patios, steps, and walls.
Cement is naturally rich in lime and salt minerals. These minerals are naturally white. When molded, concrete cures no matter what color it is, but it has a tendency to show white haze emerging to the surface or the exterior of the product. The darker the color of the cement, the more the white haze stands out. The only time this natural phenomenon is not visible is when pure white cement is used with no color.
Over time, the lime and salts that migrate to the surface of the pavers will tend to go away but then come back again. This is because when concrete gets wet and then dries, the salt and lime rises to the surface of the pavers. This occurrence is also known as “efflorescence,” and is accepted in the industry by manufactures and contractors, and it is a natural phenomenon that nobody can control.
Over the years, chemicals have been produced as additives to the concrete during manufacturing of Nicolock and Cambridge concrete products and cleaners have been developed to remove efflorescence from the surface of pavers. It has worked to a degree. Efflorescence has been minimized, but not totally eliminated from concrete manufactured products. In many situations efflorescence is very light and in others it can be very heavy. This could be caused by many factors: pour drainage, concrete that is very rich in cement, or changes in weather going from cold nights to hot days.
Over time this natural process could affect the color of the pavers. The lime and salts come up to the surface of concrete and crystallize. This could even happen to natural stones if they are installed directly on a cement base. The solution to bring the color back on the paver surface is to wait at least one year after the pavers are installed, clean and treat them with chemicals if necessary, and then seal them. The sealer will enhance the colors and eliminate the haze on the pavers surface and also protect the pavers from weathering since concrete is corrosive to the elements. Efflorescence is very common with Nicolock Cambridge Pavers, if you visit any concrete pavers manufacturers such as Techo-Bloc or Unilock  you will find that they all have instruction how to remove Efflorescence just like it is on Nicolock Cambridge Pavers.
