What Is Fill Dirt?

Definition and Composition

Fill dirt is a dense, inorganic material made up of subsoil, clay, and rock fragments. It lacks organic matter, which makes it ideal for providing a stable foundation but unsuitable for growing plants.

Best Uses for Fill Dirt

• Leveling land – Used to fill depressions and create even surfaces.
• Building foundations – Provides a compact base for construction projects.
• Road and driveway support – Enhances stability for paving and roadwork.
• Erosion control – Helps reinforce slopes and prevent washouts.

Pros and Cons

✅ Affordable and widely available
✅ Excellent for filling holes and creating stable bases
✅ Reduces settling compared to organic-rich soils
❌ Not suitable for plant growth
❌ Requires compaction for stability

Pricing Range

Fill dirt typically costs between $5 and $25 per cubic yard, depending on quality and location.

What Is Topsoil?

Definition and Composition

Topsoil is the uppermost layer of soil, rich in organic matter, nutrients, and microorganisms essential for plant growth. It comes in screened (filtered for consistency) and unscreened (contains debris) varieties.

Best Uses for Topsoil

• Gardening and landscaping – Supports healthy plant growth.
• Lawn installation – Provides a base for sod and seed.
• Flower beds and raised gardens – Supplies nutrients for flowers and vegetables.
• Erosion control – Helps stabilize slopes with vegetation.

Pros and Cons

✅ Nutrient-rich and promotes plant growth
✅ Enhances moisture retention
✅ Improves soil structure in gardens
❌ More expensive than fill dirt
❌ Can compact and reduce drainage if not mixed with other materials

Pricing Range

Expect to pay between $10 and $50 per cubic yard, with screened topsoil on the higher end.

What Is Sand?

Types of Sand

• Masonry sand – Fine-grained, used for bricklaying and playgrounds.

What Is Gravel (Aggregate)?

Types of Gravel

• Pea gravel – Small, rounded stones used for landscaping.
