Abstract
A paving slab. The paving slab has a unitary body made of concrete-based material, the body having sidewalls extending between top and bottom faces, providing the body with a thickness. The top face is provided with longitudinal false joints defining rows extending from a first to a second side of the unitary body. The first side has a staggered outline and the second side has a stepped outline, the first and second sides being able to engage with respective first and second sides of an adjacent slab shaped as the paving slab, but rotated by 180 degrees. When several of the slabs are assembled on a surface, it creates an illusion that the surface is covered by individual plank pavers randomly assembled.
