๐ก How to Calculate Fill Dirt Quantities
Fill dirt is used to raise grade, fill excavations, and create level building surfaces. The key to accurate estimation is the compaction factor โ loose fill dirt compacts 20โ30% when mechanically compacted, meaning you need to order 20โ30% more than the finished volume.
Fill dirt weighs approximately 1.15 tons per cubic yard (compacted). Standard dump trucks carry 10โ14 cubic yards per load. For large projects, ordering by the truckload is most economical. Specify 'clean fill' to ensure you get dirt free of organic matter, debris, and contaminants.
A 20ร20 ft area needing 12 inches of fill: base volume = 400 cu ft, with 25% compaction factor = 500 cu ft = 18.5 cu yd โ 21.3 tons. That's about 1.3 dump truck loads (14 yd each).
