Patent ID: 8820022

Claim:
A building unit for forming a surface covering comprising, a substantially planar base having a main body portion and having an outer periphery and at least three mating sides, wherein each mating side has at least one “S”-connection, each “S”-connection including at least one male section extending outwardly away from the main body portion and at least one adjacent female section extending inwardly toward the main body portion; and a plurality of artificial stones, including perimeter artificial stones located at the outer periphery, separated by one or more false joints on said base, wherein a first portion of each of the perimeter artificial stones is positioned proximate to said outer periphery adjacent said male mating sections, respectively, and a second portion of each of the perimeter artificial stones is positioned a set back distance from the outer periphery adjacent to a said female sections, respectively, wherein the distance between the artificial stones and the outer periphery, varies and the proximate distance to the outer periphery, relative to the male sections is generally smaller than the set back distance relative to the female sections.
