Natural stone setts
Setts in porphyry, granite, sandstone of other types or stone are often dismantled in large quantities during roadworks and are consequently easy to find on the reclamation market. Many different formats exist, and dealers will often offer to cut setts to produce a smooth surface accessible to people with reduced mobility or cyclists. Their very long lifespan and modularity make them a model product of circularity.
In recent decades, cobblestones have also often been imported from outside of Europe, such as the Kandla cobblestone from India. These stones are at the moment still rare on the reuse market.
