Epprechtstein Granit, grau-gelb
grey-yellow granite
“Epprechtstein Granit” is particularly prized for its uses in natural stonework thanks to its proven quality and its distinctive colour and texture. Numerous historical buildings bear witness to this. The good physical and technical properties of this stone allow almost unlimited interior and exterior applications. Its tested and certified frost-salt resistance is another significant asset.
The Epprechtstein quarry has been in operation for several centuries. It is one of few quarries in Germany from which grey and yellowish granite can still be sourced today.
Regional “Epprechtstein Granit” is a highly sustainable building material.

The displayed stone samples illustrate the kind of material extracted from the quarry in question. As a natural material, stone is subject to variations in colour, texture and grain structure. It can also have natural inclusions, markings or veining. A typical stone patina may develop due to material-related or environmental influences.
