Method and apparatus for constructing a surface from a plurality of similar polygonal tiles wherein the tile has affixed to 50% of its sides one or more spacer members, each spacer member having a flat base and a rectangular flange bisecting the base, said spacer members being securely affixed to the rear face of the tile or to the flat base of an indentation in said base with the flange of the spacer member resting against the side of the tile. The tile is laid onto a bed of wet cement with a projecting portion of the spacer member lying on the surface of the bed. A second tile is laid onto the bed so that the rear face of the tile will rest on the base of a spacer member affixed to the first tile with one side of the second tile resting against the flange of the said spacer member. Successive tiles are then laid on said bed with their rear faces resting upon the base of a spacer member of an adjacent tile and the side of the tile resting against the flange of the spacer member.
