Calculadora de Relleno y Relleno Compactado — ft a yd³, toneladas, camiones, costo
Cómo usar esta calculadora
Calculate volume, weight, y number of truck loads for fill y backfill operations. Choose from three area shapes: rectangle, trench, or around a foundation. Select material type (each has preset density) y apply a compaction/shrinkage factor to determine how much loose material you need to order.
Compaction factor — Loose fill shrinks 15–25% when compacted. Order 15–25% extra to reach the required compacted volume.
Materials — Clean fill (2,400 lb/yd³), structural fill (2,700), gravel (2,800), sand (2,600), clay (2,500), topsoil (2,100).

Cómo Calcular Relleno y Relleno Compactado
This calculator estimates the volume y weight of fill material needed for backfilling excavations, grading, or landscape fill. Choose from rectangular areas, trenches, or the gap around a foundation. Material density accounts for clean fill, structural fill, gravel, sand, clay, y topsoil.
Fórmulas
Compacted volume = L × W × depth. Loose volume = compacted volume × (1 + shrinkage%). Peso = volumen suelto × density (lb/yd³). Truck loads = ⌈volumen suelto / 14 yd³⌉. Foundation backfill = (outer L × W − foundation L × W) × depth.
Preguntas Frecuentes
Why order extra? Loose fill compacts by 15–25% when properly compacted per ASTM D698 (standard Proctor) or D1557 (modified Proctor). You must order volumen suelto, not compacted.
How many yards per truck? A standard dump truck carries about 14 yd³. Tri-axle holds ~16–18 yd³. Transfer trucks up to 24 yd³.
