Abstract
Abstract A paver system comprising a plurality of paver pieces and at least one substrate. Each of the paver pieces has a top surface and a bottom surface. The bottom surface of the paver pieces is configured for mating with the upper surface of the substrate, whereby paver pieces coupled to the substrate are prevented from moving laterally.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
171 words
A paver system of preassembled units comprising: a plurality of paver pieces, each of the paver pieces comprising a top surface and a bottom surface; at least one substrate supporting the plurality of paver pieces with their top surfaces in a closely spaced relationship substantially in a common plane, the paver pieces covering substantially the entire substrate and wherein the substrate further includes lift apertures for receiving the tongs of a pallet lifter; wherein the paver pieces include a coupling feature formed at the bottom surface and the substrate includes an upper surface formed with a complementary coupling feature, the paver pieces mating with the substrate via the coupling feature and the complementary coupling feature to form a paver system with column support providing substantially uniform compressive strength across the paver piece top surfaces, whereby the paver pieces preassembled on the substrate in mating relationship are prevented from moving laterally and the combined preassembled paver pieces and substrate may be placed as a unit in final position on a base surface.
Claim 2
Dependent Claim
171 words
A paver system of preassembled units comprising: a plurality of paver pieces, each of the paver pieces comprising a top surface and a bottom surface; at least one substrate supporting the plurality of paver pieces with their top surfaces in a closely spaced relationship substantially in a common plane, the paver pieces covering substantially the entire substrate and wherein the substrate further includes lift apertures for receiving the tongs of a pallet lifter; wherein the paver pieces include a coupling feature formed at the bottom surface and the substrate includes an upper surface formed with a complementary coupling feature, the paver pieces mating with the substrate via the coupling feature and the complementary coupling feature to form a paver system with column support providing substantially uniform compressive strength across the paver piece top surfaces, whereby the paver pieces preassembled on the substrate in mating relationship are prevented from moving laterally and the combined preassembled paver pieces and substrate may be placed as a unit in final position on a base surface.
