Detailed Specifications
Cobble Stone Paving G684 Black Basalt Cobble stone paving is a traditional method of paving streets and sidewalks that involves using small, rounded stones, typically made of granite, to create a smooth and durable surface. The stones, which are also known as cobbles, are carefully arranged and set in a bed of sand or mortar to create a stable and long-lasting pavement. Cobblestone paving has a long history, with evidence of its use dating back to ancient Rome and other civilizations.
