Sander Sandstein

green sandstone

honed

This green Mainsandstein, also known as “Sander Schilfsandstein” (reed sandstone), is especially valued for its characteristic colour and texture and also for its versatile applications. This material can be found in many historical and contemporary buildings, both indoors and outdoors. Thanks to its physical and technical properties, the stone resists weathering well. The fact that it has been tested and certified accordingly may provide you with one more reason to use it.

The quarry in Sand has been in operation for more than 1000 years. It is now among the last actively worked quarries extracting this green sandstone.

Regional “Sander Sandstein” is a highly sustainable building material.

Proof and confirmation of suitability by EC declaration of conformity, as well as CE marking available. We will be happy to provide you project related with references, test reports and further information.

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.
