Considerations For Modular Concrete Products
Color Variations
As in all natural materials,
color in paving stones has inherent variations. Paver color is affected
by the variances in the raw materials, concrete mixture moisture content
and climactic conditions and other variations. Therefore, the colors shown
are approximate representation of PAVESTONE’s standard paver colors, but
should not be expected to be an exact match of what will be delivered.
The
Nature of Efflorescence
Another cause of color variations
in pavers may be the natural phenomenon called efflorescence. Efflorescence,
a deposit of white salts consisting of mostly calcium carbonate, may appear
as a white powder on the paver surface and in no way affects the structural
integrity. This phenomenon occurs in all concrete and although it cannot
be completely prevented from occurring, efflorescence generally will weather
off and disappear over time or can be removed with cleaners at the job
site.
