Wooden tiles including a plurality of smaller rectangular blocks, flat grain or preferably end grain, are made by providing in each block at least one lateral groove extending parallel to and spaced inwardly from the end edges of the block, at least one longitudinal groove extending parallel to and is spaced inwardly from the side edges of the block and intersecting the lateral groove(s) at a right angle. When the blocks are aligned in abutting relationship, either side by side, side to end or end to end, to form a tile of the desired pattern, the grooves are aligned to form a grid-like network of continuous, rectilinear channels. The channels are substantially filled with a relatively flexible, synthetic plastic material capable of becoming flowable upon being heated to a predetermined temperature and hardening upon subsequent cooling. A portion of the plastic material is diffused into the wood in the immediate vicinity of the channels while in a flowable state and becomes bonded to the wood upon cooling to thereby hold the blocks together and yet permit movement of the blocks relative to each other. In one embodiment, the plastic material is preformed into a grid including intersecting ribs which fit into the channel network and sufficient heat and pressure are applied to the top edge of the ribs to cause a portion thereof to become flowable and diffused into the wood. In another embodiment, the plastic material is extruded into the channel network to effectively form a grid in situ.
