A floor or like tile consists either of a single piece composed of any one of a range of different materials or of a plurality of superimposed laminations each composed of any one of the said range of materials, and is formed with a plurality of identical, laterally projecting tongues and, in its underside, with an equal number of identical pockets which open to the periphery of the tile and alternate, around the periphery, with the tongues, the tongues and pockets being so shaped that any tongue of any one of the tiles is adapted to engage and fit within any pocket of any other of the tiles and when so engaged, is held against endwise withdrawal from the pocket so that, when the two tiles are located in a common plane, relative movement therebetween in the said plane, is prevented.
