A ground covering element having the basic shape of a square. All four basic sides of the around covering element have an engaging profile, each profile being symmetric with respect to a central axis of symmetry. Opposite engaging profiles are mirror images. Each engaging profile is complementary with the adjacent engaging profile. Each of the four corner regions of the ground covering element of a first type have a protrusion substantially the shape of a rectangular, isosceles triangle or of an area element similar to this triangle with curved legs. A ground covering element of a second type (42) is obtained by omitting the four protrusions from the ground covering element of the first type. The ground covering element of the second type may be laid together with additional ground covering elements of the second type or in combination with ground covering elements of the first type.
