Sloping-site retaining structure · Homeowners, engineers & contractors
Estimate earth-retaining wall cost for sloping plots—stone masonry gravity, RCC cantilever or gabion—including excavation, backfill drainage, weep holes and editable rates.
Example rates only — replace with local quotes
Resists earth pressure by weight alone. Common and economical up to roughly 3 m of retained height. Rates assume reasonable site access for stone, sand and machinery. Steep hill plots, hand-carried material and monsoon working can add substantially. Contingency is set higher than other calculators here because retaining work meets more surprises below ground.
Your estimate
A stone masonry gravity wall planning estimate from the length, retained height and rates you entered.
0.5 × retained height — a designed section may differ
2.125 m³ per running metre × 20 m
42.5 m³ × NPR 6,500
Gravity and gabion walls carry no reinforcement
37 m³ × NPR 450
15 m³ (300 mm drainage layer) × NPR 1,400
14 holes at 1.5 m spacing × NPR 350
≈ NPR 7,332 per m² of exposed face
Planning estimate only—not a structural design. Retaining walls fail dangerously when earth pressure, surcharge from a building above, water pressure behind the wall, bearing capacity, sliding and overturning are not checked by a licensed structural or geotechnical engineer. Use this for budgeting, never for construction.
