Standard Material Yield & Density Specs:
- Wall Blocks: Calculated based on net course rows and horizontal block coverage per linear run.
- Cap Stone Row: Top finish row spanning full length. Deducted from vertical block height when enabled.
- Backfill Gravel Density: Standard crushed stone/gravel backfill uses bulk density of roughly 1,600 kg/m³ (1.6 t/m³).
- Drainage Zone: A 30 cm backfill trench reduces hydrostatic water pressure behind retaining walls.
