Floor tiles are disclosed which comprise a carrier layer and a superimposed floor surface forming layer which is provided with a decorative wear resistant surface. In one embodiment the carrier layer protrudes beyond the floor surface layer on two sides and the floor surface layer protrudes beyond the carrier layer on the other two sides and the floor surface forming layer defines an angular groove and a bevelled tongue to enable adjacent tiles to be interlocked. In an alternative embodiment of the invention the groove and tongue are formed to have different angles.

A tile for forming a floor wall or the like comprising a generally planar rectilinear member including a carrier layer and a superimposed surface layer; each of said layers having two pairs of mutually parallel side edges, one of said pairs comprising two adjacent side edges; and the other of said pairs comprising the other two side edges; the edges of the carrier layer in one of said pairs being formed with a groove and the corresponding edges of said surface being formed with a vertically square end; the edges of the carrier layer of the other of said pairs being formed with a tongue, the corresponding edge of said surface being formed with a vertically square end; the bottom surface of said groove and tongue being planar and parallel with the lower surface of said rectilinear member, the upper surface of said groove and tongue being slanted with respect to the bottom surface thereof to form an acute angle; the extent of said tongue being less than the depth of said groove, and the angle of the groove being less than the angle of the tongue, whereby the tongue of one tile and the groove of another tile are cooperable to permit penetration of the tongue into the groove to an extent less than the depth thereof, with the square ends of the surface abutting each other to provide a smooth extended surface and said tongue and groove providing a space therebetween for receipt of adhesive, said tongue and groove and abutting floor surface preventing escape of adhesive therefrom.
