STEP ONE \| Prepare the site	STEP TWO \| Set Base Course	STEP THREE \| Pin, Stack & Fill
Start by digging a shallow trench 8" deep by 16" wide. Cut through and remove any sod, roots or large rocks. Place 4" leveling pad of compacted sand or gravel in the trench to receive the first course of Keystone Palazzo Stone.	Place and level the first Palazzo Stone unit. Level each additional unit on the base course as you place it, making sure that the outside edges touch. If your wall contains both straight and curved areas, start with a straight area and build into the curves. Complete the base course before proceeding to the second course. Note: For straight line walls, unit faces can be alternated to create a more random look.*	Starting with straight areas first, begin placing the second course. Center each Keystone Palazzo Stone unit over the pins on the joints of the course below in a running bond pattern as shown.Now proceed to the next layer, backfilling as you go. For drainage between units and behind the wall, clean gravel or crushed stone is recommended.
