Claim:
An interlockable tile ( 100 ) including: a plurality of sets of upper surface arrangements ( 110 A- 110 C, 110 A′- 110 C′) and a corresponding plurality of underside arrangements ( 109 ′), with a first one of the sets of the upper surface arrangements ( 110 A- 110 C) and a first one of the underside arrangements being located at or adjacent a first side edge ( 104 C) of the tile ( 100 ) and a second one of the sets of the upper surface arrangements ( 110 A′- 110 C′) and a second one of the underside arrangements being located at or adjacent an opposite side edge ( 104 D) of the tile, in use, the upper surface arrangement of the tile interlocking with a corresponding underside arrangement on an overlapping tile; a first formation ( 114 ) at or adjacent a side edge ( 104 C), and a second formation ( 112 ) at or adjacent an opposite side edge ( 104 D) that, in use, interlocks with a corresponding said first formation of an adjacent tile, characterized in that each of the underside arrangements ( 109 ′) and/or each said set of the upper surface arrangements ( 110 A- 110 C, 110 A′- 110 C′) of the tile includes a plurality of formations spaced from an upper or lower edge of the tile by different distances so that, in use, the plurality of formations provide a range of tiling gauges for the overlapping tiles.
