Question 1

What is fill dirt and when do I need it?

Accepted Answer

Fill dirt is soil material used to raise ground levels, fill holes, or create level surfaces for construction and landscaping. You need fill dirt for projects like leveling yards, filling in low spots, creating raised garden beds, preparing foundations, or improving drainage. It's different from topsoil as it's typically less fertile but more stable for structural purposes.

Question 2

How do I calculate how much fill dirt I need?

Accepted Answer

To calculate fill dirt needs: 1) Measure the area length and width in feet, 2) Determine the desired fill depth in inches, 3) Calculate area (length × width), 4) Convert depth to feet (inches ÷ 12), 5) Calculate volume (area × depth), 6) Convert to cubic yards (volume ÷ 27). Our calculator handles all these conversions automatically.

Question 3

What's the difference between topsoil and fill dirt?

Accepted Answer

Topsoil is the upper layer of soil rich in organic matter, nutrients, and microorganisms - ideal for planting and gardening. Fill dirt is subsoil material with less organic matter, more stable structure, and better compaction properties - ideal for leveling and structural fill. Topsoil costs more but supports plant growth, while fill dirt is cheaper and better for construction.

Question 4

How much does fill dirt cost per cubic yard?

Accepted Answer

Fill dirt costs vary by type and location: Fill dirt $10-20/cu yd, Topsoil $20-40/cu yd, Clay $15-25/cu yd, Sand $25-40/cu yd, Gravel $30-50/cu yd, Crushed stone $35-60/cu yd. Prices depend on local availability, delivery distance, and material quality. Delivery costs are typically additional.

Question 5

How many cubic yards are in a truck load?

Accepted Answer

Truck load capacity varies by vehicle type: Small dump truck (6-8 cu yd), Standard dump truck (10-12 cu yd), Large dump truck (15-20 cu yd), Semi-trailer (20-25 cu yd). Our calculator assumes 10 cubic yards per truck load, but check with your supplier for exact capacity and delivery options.

Question 6

What is soil compaction and why does it matter?

Accepted Answer

Soil compaction is the process of compressing soil particles to increase density and reduce air space. Compaction levels affect: Loose (no compaction) - 100% volume, Moderate (light compaction) - 110% volume, Heavy (standard compaction) - 120% volume, Very heavy (maximum compaction) - 130% volume. Higher compaction means you need more material to achieve the same final volume.

Question 7

How do I choose the right type of fill material?

Accepted Answer

Choose fill material based on your project: Topsoil for planting areas, Fill dirt for general leveling, Clay for areas needing water retention, Sand for drainage improvement, Gravel for driveways and paths, Crushed stone for structural applications. Consider drainage needs, load requirements, and future use when selecting materials.

Question 8

What should I consider for delivery and placement?

Accepted Answer

Delivery considerations include: Access for trucks (width, height, weight limits), Placement location (avoid utilities, structures), Weather conditions (avoid wet conditions), Equipment needs (excavator, compactor), Permits and regulations, Neighbor considerations, and Cleanup requirements. Plan delivery timing and placement strategy in advance.

Question 9

How do I prepare the area for fill dirt?

Accepted Answer

Area preparation steps: 1) Mark the area boundaries, 2) Remove existing vegetation and debris, 3) Check for utilities and mark locations, 4) Grade the area to proper slope, 5) Install drainage if needed, 6) Compact the existing soil, 7) Plan for material placement and spreading, 8) Arrange for equipment and labor as needed.

Question 10

What are common mistakes when ordering fill dirt?

Accepted Answer

Common mistakes include: Underestimating volume needed, Not accounting for compaction, Choosing wrong material type, Not considering delivery access, Ignoring local regulations, Not planning for equipment needs, Forgetting about cleanup, Not checking material quality, and Not getting multiple quotes. Our calculator helps avoid volume and cost estimation errors.
