5. Build Your Wall Sweep the top of each course of units to clear debris. Half-stagger the next course so each unit is centered on two units below. Pull each unit forward to lock connecting lugs in place. 6. Install Backfill Place perforated drainage pipe behind the base of the wall. Add 12 inches of free-draining aggregate behind the wall. Fill the hollow core of the units with the same materials. Place the backfill materials in layers of no more than 12 inches deep. Compact each layer well, making sure to keep the compaction equipment 12 inches away from the back of the wall. 7. Reinforce Walls Place the geosynthetic according to the engineer's plan drawings and specifications. Place the geosynthetic on top and as close to the front of the units as possible. Lock the next course of units into place. Gently tension the geosynthetics toward the back of the compacted backfill. Repeat the backfilling steps. Always work from the back of the wall toward the end of the reinforced zone.
