How to Convert Oven Recipes to Air Fryer
Fill dirt is used to raise grades, fill holes, and prepare building sites. The key to ordering the right amount is accounting for compaction — loose dirt settles 15-25% when compacted.
The basic rule:
- Volume: Area (sq ft) × Depth (inches) / 12 = cubic feet. Divide by 27 for cubic yards
- Compaction factor: If you need 10 yd³ of compacted fill, order 12 yd³ (20% extra) to account for settling
- Fill dirt weighs approximately 2,000 lbs (1 ton) per cubic yard. Clean fill may weigh slightly more
Clean fill dirt is free of organic matter, debris, and contaminants. It is required for most construction projects. Structural fill must be placed in 6-8 inch lifts and compacted to 95% density with a plate compactor or roller.

Frequently Asked Questions
What is the difference between fill dirt and topsoil?
Fill dirt is subsoil — it lacks organic matter and nutrients, making it stable for building on. Topsoil is the nutrient-rich top layer used for growing plants. Never use topsoil as structural fill (it settles) and never plant in fill dirt (nothing grows well in it).
How much does fill dirt weigh?
Fill dirt weighs approximately 2,000 lbs (1 ton) per cubic yard when dry and loose. Compacted fill dirt weighs about 2,400-2,600 lbs per yard. Wet fill dirt can weigh up to 3,000 lbs per yard. Always account for moisture when estimating truck capacity.
What is a compaction factor?
Loose fill dirt contains air pockets. When compacted (tamped, rolled, or vibrated), it loses 15-25% of its volume. If you need 10 cubic yards of compacted fill in place, you need to order 12-12.5 cubic yards of loose fill dirt to end up with the right amount.
How much does fill dirt cost?
Fill dirt costs $5-$25 per cubic yard, plus $50-$200 for delivery. Clean fill (tested, debris-free) costs $10-$30/yard. Some excavation contractors give away fill dirt for free — check local classifieds. Delivery is the biggest cost for small quantities.
How do I compact fill dirt properly?
Place fill in 6-8 inch lifts (layers). Compact each lift with a plate compactor or jumping jack before adding the next. Moisten the dirt slightly for best compaction — not muddy, just damp. For structural fill, compact to 95% Proctor density per engineering specs.
Can I use fill dirt for grading around my house?
Yes, fill dirt is ideal for grading. Slope the grade away from your foundation at 1 inch per foot for the first 6 feet. Cap the fill dirt with 4-6 inches of topsoil for planting. Do not use fill dirt that contains debris, concrete chunks, or organic matter.
