Caps or pavers can be used for treads. Check local building codes for any tread depth standards. BASE COURSE Thoroughly compact the leveling pad. Lay out the base course according to the wall design. Place step units first, working from the center to each side. Remember, it is very important to backfill and compact behind and along the sides of each course of step units. FIRST STEP COURSE Place the first course of step units directly on top of the base course so there is no setback. Stagger them from the previous course and glue in place. SECOND STEP COURSE Add the second course of steps, staggering them from the previous course to maintain running bond. Overlap the lower course by a minimum 2 inches and glue to lower course. Place and compact base material prior to installing next course. SECOND WALL COURSE Build the second course of the wall. Corner units are used at the end of steps tied into wall and glued in place. Alternate long and short direction of corner unit every other row. THIRD STEP COURSE Beginning in the center, add the third course of steps, lining up the units with the first course. Overlap the lower course by 2 inches and glue to lower course. ADDITIONAL COURSES Build the third course of the wall. Repeat these steps until the wall is finished. Remove lips so walls stack vertically. Glue all units.
