Fill Dirt in Wildwood, MO

Fill-dirt is subsoil (low-organic earth) used to raise grade, fill depressions, and build engineered pads. In Wildwood you would use it for grading a yard, raising low spots, backfilling foundations, or creating a base before placing structural fill or gravel; it is not intended as planting topsoil because it lacks organic matter.

Use this rule: cubic yards = (area in sq ft * depth in inches) / 324. For a 1,000 sq ft area you need about 6.2 cu yd (≈8.6 tons) at 2u0022, 12.4 cu yd (≈17.3 tons) at 4u0022, and 18.5 cu yd (≈25.9 tons) at 6u0022, assuming a typical fill-dirt density of about 1.4 tons per cubic yard; scale these numbers to your exact area.

Prices vary by source, haul distance, volume, and seasonal demand, but delivered fill-dirt in the Wildwood/St. Louis area commonly falls roughly in the low-to-mid tens of dollars per ton. For an exact delivered price for your address and quantity, request a quote through Hello Gravel since we connect you to local suppliers and show transparent pricing.

Hello Gravel connects you with local suppliers and haulers serving Wildwood and the St. Louis metro, and we can provide quotes and delivery options for bulk fill-dirt. For installation and compaction work, look for local landscape contractors or earthwork contractors in Wildwood or nearby St. Louis suburbs and ask for references and proof of insurance.

Missouri clay soils and seasonal freeze-thaw cycles can cause movement and heaving if fill-dirt contains organic matter or is poorly compacted. Properly placed fill-dirt, installed in controlled lifts with compaction and attention to drainage, performs acceptably, but for frost-susceptible locations consider engineered fill or granular material and ensure positive site drainage.

Fill-dirt can be used as structural subgrade but is not a recommended final base layer under driveways, patios, or pavers because it typically lacks the granular stability and drainage of crushed stone. Use fill-dirt to bring grades to elevation, then place and compact a proper granular base (e.g., crushed stone) before paving or installing pavers.

Hello Gravel has a 3-ton minimum order and works with local haulers using tri-axle dump trucks; standard delivery is typically 2+ business days with next-day options before noon CST for an extra fee. Delivery fees depend on supplier distance, access, and neighborhood restrictions; many areas offer free delivery for nearby suppliers, while longer hauls or special access requirements may incur per-mile or drop fees—get a quote for exact costs.

Fill-dirt is subsoil with low organic content and is best for structural fill and grading; it compacts well but drains slower than sand. Clean fill sand drains quickly but may not compact as uniformly for load-bearing applications, while topsoil contains organic matter and is intended for planting, not structural fill—choose based on whether you need stability (fill-dirt), drainage (sand), or planting medium (topsoil).

Many Wildwood projects that change grade, alter drainage, or move large volumes of earth may require permits or erosion control measures from the City of Wildwood or St. Louis County. Before ordering large loads, contact Wildwood Building and Public Works or check local ordinances to confirm whether grading, stormwater, or erosion-control permits are required for your project.

Newly placed fill-dirt typically settles most in the first 6 to 12 months, with minor settling possibly continuing for a few years if not compacted properly. Proper lift thickness, compaction, and moisture control reduce long-term settlement; expect to inspect and possibly top-up low spots within the first year on DIY installations.

Compact fill-dirt in lifts (typically 6 to 8 inches) using the right equipment: plate compactors or vibratory plate compactors for small areas, walk-behind rollers for medium work, and vibratory or pneumatic rollers for larger sites. Conditioning moisture to near optimum before compaction, compacting each lift, and testing compaction where structural stability matters are all best practices; hire a contractor for larger or engineered fills.
