A synthetic surface element having a central core of filler material, for example wood chips, saw dust, foam, or any other inert filling material, said central core being disposed between top and bottom layers of thermaplastic or thermaset material, the outer perimeter of the synthetic surface element being provided with first flanges extending substantially outwardly from the thermaplastic or thermaset material covering the top of the central core and said flanges having substantially downwardly extending supplementary flanges located proximate the terminus of the first flanges, the length of the supplementary flange being greater than the distance between the top and bottom surfaces of the layers covering the central core filler so as to define proximate the bottom of the synthetic surface element a continuous channel bounded by the supplementary flange and the central core, wherein in placing said synthetic surface element in engagement with a supporting surface, for example a gravel or aggregate bed, the hollows will engage with the supporting elements, for example the aggregate sand or the like, and position the synthetic surface element, and prevent it from moving in relation to the supporting surface.
