Abstract: A system for providing a veneer for a surface, comprising a first plurality of veneer blocks, each having dimensions of 1N by 3N, where N is a unit of length. A second plurality of veneer blocks, each having dimensions of 1N by 4N. A third plurality of veneer blocks, each having dimensions of 2N by 3N. A fourth plurality of veneer blocks, each having dimensions of 2N by 4N, wherein the first plurality of veneer blocks, the second plurality of veneer blocks, the third plurality of veneer blocks and the fourth plurality of veneer blocks are provided as the veneer on the surface.

Abstract: A precast, crushed stone landscape edging module comprises block body, a first, bidirectional interlocking joint, and a second, bidirectional interlocking joint. The block body has a first outer surface and a second outer surface and a first end surface extending from the first surface to the second surface and a second end extending from the first surface to the second surface. A first bidirectional, interlocking first joint is disposed on the first end surface and a second bidirectional, interlocking joint is disposed on the second end surface, wherein the first bidirectional, interlocking joint adapted to interlock with the second bidirectional, interlocking joint to prevent slippage and to enable rotation of the block body. The first bidirectional, interlocking joint has a first sawtooth and a first recess positioned adjacent to and joining the first sawtooth. The first recess is designed to receive a second sawtooth with a shape and dimension comparable to the first sawtooth.
