Concrete Wall Calculator
This concrete wall calculator covers poured-in-place walls and retaining walls: length × height × thickness. Filling concrete block instead? See the grout calculator for block fill / core fill quantities per square foot of wall.
इस कैलकुलेटर का उपयोग कैसे करें
- अपने आयाम दर्ज करें — लंबाई के लिए फीट, मोटाई के लिए इंच.
- विकल्प समायोजित करें — अपव्यय प्रतिशत, बैग का आकार और आपके स्थानीय कंक्रीट की कीमत।
- अपने परिणाम पढ़ें — टाइप करते ही आयतन, बैग, वजन और लागत लाइव अपडेट होते हैं।

Wall volume = Length × Height × Thickness हल किया गया उदाहरण: A 20 ft retaining wall, 4 ft tall × 8 in thick: 20 × 4 × 0.667 = 53.3 ft³ ÷ 27 ≈ 1.98 yd³ — order 2.2 yd³ with waste.
A retaining wall concrete calculator is just the slab formula stood upright — but walls consume concrete quickly because the full height counts, not a 4-inch slab depth. An 8-inch-thick wall uses one cubic yard for every 40 square feet of face.
For CMU (block) walls, you don't pour the wall — you fill the cores. A block fill calculator / core fill calculator works from wall area and block size: an 8 inch block wall fully grouted takes about 1.12 yd³ per 100 ft² of wall. Our grout calculator does this per cell spacing.
Retaining walls above 3–4 ft usually require engineering: footing size, rebar schedule, drainage and batter all matter more than the raw volume.
अक्सर पूछे जाने वाले प्रश्न
concrete wall calculator के बारे में सामान्य प्रश्न।
How much concrete for a poured wall?
Length × height × thickness in feet ÷ 27. A 30 ft × 8 ft foundation wall at 8 in thick needs 30 × 8 × 0.667 = 160 ft³ ≈ 5.9 yd³.
How much grout to fill concrete block cores?
Fully grouted: about 0.93 yd³ per 100 ft² for 6 in block, 1.12 yd³ for 8 in block, 1.73 yd³ for 12 in block. Partial grouting scales down with cell spacing — use our core fill calculator.
How thick should a retaining wall be?
Poured retaining walls are typically 8 inches minimum, increasing with height. Walls over 4 ft tall should be engineered with a proper footing and drainage.
Does the calculator handle both wall types?
This page computes poured wall volumes. For block fill / core fill quantities, the grout calculator has per-block-size yields and cell spacing options.
