ABSTRACT:
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.
