Abstract: A mosaic tile assembly manufactured in a mold via a continuous plastic injection process. The tile assembly comprises a plurality of tiles disposed in a staggered, offset arrangement of rows that avoids the intersection of four tile corners. Each mosaic tile generally comprises a front face configured for exposure to the exterior and back face configured for attachment to the floor or wall surface. The back face comprises a surface and a plurality of grooves disposed in a predetermined array of perpendicularly disposed vertical and horizontal grooves. The horizontal grooves of successive adjacent tiles within a row may be aligned with one another whereas different vertical grooves of adjacently disposed tiles, above and below, may be aligned with one another to form the offset arrangement. The tile assembly may also comprise a plurality of interconnecting links that may formed in the same mold during the same plastic injection process.
