Abstract

An interlocking paver system including polygon and spacer pavers. The polygon paver has a longitudinal axis extending from a first to a second side and a transverse axis orthogonal to the longitudinal axis and extending from a third to a fourth side. The spacer paver has a longitudinal axis extending from a first to a second side and a transverse axis orthogonal to the longitudinal axis and extending from a third to a fourth side. Both the polygon and spacer pavers are symmetrical about the longitudinal and transverse axes. The spacer paver is configured to selectively interlock with the polygon paver with either of the third or fourth side of the polygon paver adjacent either of the first or second side of the spacer paver and either of the first or second side of the polygon paver adjacent either of the third or fourth side of the spacer paver.
