Step 1 Prepare Base Begin by excavating a trench approximately 12 inches wide by 4 inches deep. It is important to remove sod and other organic materials. It is also important to partially embed a portion of the bottom course to hold it firmly in place. After excavating, make sure that the bottom of the trench is well compacted. Use a hand tamper to compact the soil if necessary. Spread a 1-inch layer of sand in the trench. The base is now ready for the base course of Handy-Stone II.
Step 2 Position Base Course Lay the base course units on your prepared base. You may remove a small amount of sand to make room for the alignment lips, remove alignment lips, or place base units upside down with alignment lips facing forward. Level each unit side to side, front to back, and with adjacent units. A rubber mallet will help to level units and a string line can be used to keep units straight.
Step 3 Lay Succeeding Course Position the second course of Handy-Stone II units so that alignment lips overhang the back edge of the base course and edge joints are staggered with those of the lower units.
Step 4 Backfill As You Proceed Backfill behind each course as you proceed. Gravel backfill is recommended to help with drainage. Continue laying additional courses and backfilling until desired height is achieved.
Step 5 Secure Top Course (optional) If it is critical to prevent units from being removed, secure them using a good concrete adhesive.
