Retaining Wall Material Estimator
Material Estimates
Formulas:
Blocks = (Wall Length * 12 / Block Length) * (Wall Height * 12 / Block Height) (rounded up)
Caps = Wall Length * 12 / Cap Length (rounded up)
Base Gravel (cu yd) = (Wall Length * (Block Depth/12) * 0.5) / 27
Backfill (cu yd) = (Wall Length * (Block Depth/12) * (Wall Height - 0.5)) / 27
