Abstract: A tile system has been devised that includes novel, integral self-aligning and self-spacing features on the side walls of the tiles to provide uniform self-alignment continuously during installation in all directions, both on vertical and horizontal surfaces. Border and corner tiles with similar self-alignment features are shown. The self-alignment features will align the tiles in either a straight-laid or running bond (or brick) pattern.

The self-alignment features have application with bonded and non-bonded tiles, driveway/walkway/deck pavers and mortared interior and exterior brick, which can be manufactured in a variety of materials and processes. This Invention pays particular attention to plastic injection molded tiles that are to be bonded to a surface and subsequently grouted.
