Stone Granules – Flint
The visible side of our prefabricated concrete elements may also be aesthetically finished with natural stone granules known also as flint. There is a large variety of colors, with the further coloring effect of the natural stone granules being influenced by the underlying color of the cement applied.
A surface retarding agent is applied before pouring the metal on formwork tables, then the mixture of concrete and stone aggregates is poured and vibrated. After the element is stripped, the surface retarding agent is high-pressure cleaned in a specially equipped car wash, so that the stone granules become visibly embossed.
