More than four thousand years ago, the first transport routes were paved with cobblestones. The use of natural stone as a paving surface has evolved significantly over the last 100 years. Today, rather than being laid as road surfaces, paving stones are mainly used for creative pavement designs. A wealth of knowledge and experience is required to properly plan and implement a paving project. Since its founding in 1917, WALO has been paving large and small surfaces for public and private sector clients in Switzerland. Steeped in tradition, paving stones are deservedly held in high regard.
