Claim:
A tile simulating four tiles with a reticulated mesh support and free assembly which comprises: an upper end and a lower end which are connected by longitudinal edges to define the tile; said upper end comprising connecting means for being connected to the lower end of an adjacent tile, support means being provided along at least one of said longitudinal edges; two upper simulated tile areas and two lower simulated tile areas, both of said simulated tile areas opposite said longitudinal edge having said support means being convex and said two of said simulated tile areas adjacent said longitudinal edge having said support means being concave, each of said simulated tiles having a trapezoid configuration as seen in plan, a generally flat area extending longitudinally between said concave simulated tiles and said longitudinal edge having said support means, said flat area adapted to receive an outboard longitudinal edge of said two convex simulated tiles of an adjoining tile; channel means being provided obliquely across said flat area to guide fluid flow from adjacent said longitudinal edge having said support means to the respective concave simulated tiles.
