<p>A pillar slab system using precast concrete pillar slabs for constructing a pillar, pergola or other stone structure comprises a body comprising at least four sides. Each exterior side surface comprises at least one simulated stone face. At least first and second side surfaces also have at least one simulated joint defining a visual separation between simulated stone faces. The simulated joints in the side surfaces are disposed at different horizontal positions, so that when one pillar slab is stacked on an identical pillar slab in a different orientation, the simulated joints in adjacent surfaces are vertically staggered relative to one another to avoid obvious repeating patterns and provide the appearance of a natural stone construction.</p> |
