ABSTRACT OF THE DISCLOSURE A ground covering element which, provided as a normal ground covering element for overlaying entire areas, has projections and recesses at all sides for interlocking engagement with adjacently laid ground covering elements, comprising a unitary, rigid body, with a pair of inner side surfaces arranged at generally right angles to each other to form an inner angle; a pair of outer side surfaces arranged at generally right angles to each other to form an outer angle, the angles having a common bisector; two end surfaces, each extending generally perpendicularly between respective inner and outer side surfaces; and two gaps provided in the top surface of the element to form lines of structural weakness, and arranged at generally right angles to each other with each extending from the inner angle of the element to a mid-point along the respective outer side surface, such that the top surface of the element appears to consist of three substantially identical four-sided elemental units arranged in a generally right-angle form with the profile of each elemental unit's side being such that when an imaginary straight base line is drawn between the ends of a side, at least one side portion projects outwardly therefrom and at least one side portion projects inwardly therefrom.
