Calculadora de Grava y Agregados — m a toneladas, m³, costo
Cómo usar esta calculadora
Select an area shape (rectangle, circle, triangle, L-shape, or enter area directly), enter dimensions y choose the unit (m, cm, or mm), set gravel depth, y choose the material type. Los resultados se actualizan instantáneamente with volume, weight, cobertura, y truck loads.
Material — select from 10 aggregate types; each has a different bulk density that affects weight y truck loads.
Costo — price per tonne or per m³. Set truck capacity to estimate delivery loads.
Compaction — gravel compacts 5-15% during installation; the waste/compaction slider accounts for this.

Cómo Calcular Grava y Agregados (Metric)
This gravel calculator estimates volume en metros cúbicos y weight en sistema métrico tonnes for 10 common aggregate materials per EN 13242. Enter the cobertura area dimensions y choose the unit (m, cm, or mm), set the desired gravel depth (typical: 5 cm for walkways, 10 cm for driveways, 15 cm for structural base courses per EN 13285), y choose the material type. The waste/compaction slider accounts for material loss during spreading y compaction.
Fórmulas
Volume: Area (m²) × Depth (m) = Volume (m³). Weight: Volume (m³) × Density (kg/m³) ÷ 1,000 = Weight (tonnes). Common densities: Gravel/Crushed stone 1,600 kg/m³, Sand 1,500 kg/m³, Topsoil 1,070 kg/m³, Mulch 360 kg/m³.
How Many Tonnes of Gravel Do I Need?
For a 6×3 m driveway at 10 cm depth: 18 m² × 0.10 m = 1.80 m³. At 1,600 kg/m³: 1.80 × 1,600 ÷ 1,000 = 2.88 tonnes. Add 10% for compaction: about 3.17 tonnes. A standard truck carries 10-14 tonnes, so one load is sufficient for most residential projects.
Preguntas Frecuentes
What depth of gravel for a driveway? 10-15 cm is standard: 10 cm compacted base + 5 cm surface layer. How much does a cubic meter of gravel weigh? About 1,600 kg (1.6 tonnes) for standard gravel; sand weighs about 1,500 kg/m³. How much area does 1 tonne of gravel cover? At 5 cm depth, about 12.5 m²; at 10 cm depth, about 6.25 m².
