Laying the First Row

Some Unilock® retaining wall products must be split. Use a 3lb. Mallet and a 3” – 4” chisel to split blocks along the center groove. This gives each unit the natural split face appearance. If your design has a corner, start by using a corner unit. Place each unit directly on the compacted gravel base, leveling each one with a carpenter’s level. Make adjustments with small amounts of sand and a rubber mallet. Take your time and do this properly.
