Abstract
A paving element for the water-permeable reinforcement of surfaces, said paving element comprising a top surface, a bottom surface and a plurality of sides. One or more of the sides have vertical recesses extending from the top surface of the paving element to the bottom surface. The recesses are disposed asymmetrically about the mid points of the sides such that recesses of the adjacent sides of neighboring elements are offset from one another when the neighboring elements are laid in alignment, thereby avoiding alignment of the recesses. Alternatively, an offset of the recesses on neighboring stones is achieved by laying the elements in a displaced or staggered manner.
