    • Mark & Dig • Mark an outline of your project. Then dig a shallow trench 8 inches deep by 14 inches wide.
    • Base & Tamp • Add 4 inches of granular base material. Compact base to avoid settling.
    • Level • When burying the first course of units, it is very important to level them from front-to-back and side-to-side.
    • Stack • Place the next course of units centered over the two units below and continue until your wall is complete. Make sure your wall is not taller than 36 inches.
    • Cap • Finish the wall with a cap unit to give it a polished look. Secure in place with concrete adhesive.
    • Optional Lip Removal • To remove outside lugs or edges of retaining lip, hold unit securely or place at angle on ground. Strike the lug firmly with a hammer. Always wear safety glasses to protect eyes from chips.
