Fill Dirt in O'Fallon, MO

Fill dirt is mostly soil with low organic content meant for building up and compacting grade; it is not decorative and does not drain like gravel. Gravel is rock used for drainage and finished surfaces. In O'Fallon, suppliers source local fill dirt that may be clay or silt-rich, so it compacts well but holds moisture more than washed stone.

Generally, fill dirt is cheaper per ton than crushed gravel because it is less processed and often locally available. Final price depends on delivery distance, volume, and supplier; request a Hello Gravel quote for an accurate delivered price to O'Fallon. Keep in mind minimum orders and trucking can affect the per-ton cost.

Yes, buying larger quantities usually lowers the per-ton price because suppliers and haulers offer better rates for full truckloads. Hello Gravel has a minimum order of 3 tons, and larger orders (yard or truckload) often reduce unit cost. Ask for a bulk quote through our site to see volume discounts for O'Fallon deliveries.

Coverage depends on depth and soil compaction, but a useful rule is that 1 cubic yard covers about 108 sq ft at 3 inches depth. One ton of fill dirt is roughly 0.75 to 0.85 cubic yards depending on moisture, so you can expect about 80 to 90 sq ft at 3 inches as a rough estimate. For precise needs, use the cubic-yard calculation below and request a quote.

Multiply your area in square feet by desired depth in inches, then divide by 324 to get cubic yards (area * depth / 324 = cubic yards). To convert to tons, multiply cubic yards by about 1.3 (approximate tons per cubic yard for local fill dirt) or ask Hello Gravel for a more exact factor from the supplier. Example: a 10x10 area (100 sq ft) at 4 inches needs about (100*4)/324 = 1.23 cubic yards, roughly 1.6 tons.

Yes, you can add fill dirt to raise low spots, but it must be placed in thin lifts and compacted to avoid future settling. In O'Fallon’s freeze-thaw climate, poor compaction can cause uneven settling in spring, so compact each layer and avoid piling large depths at once. If you plan to plant lawn, top the fill dirt with a few inches of topsoil for seed germination.

Fill dirt is commonly used to correct grades and build up low areas before landscaping in O'Fallon. Use it for bulk elevation, then finish with 2-4 inches of topsoil for planting or sod. Always compact the fill in 4- to 6-inch lifts and maintain a slope away from foundations for proper drainage.

No, 2 inches of fill dirt is generally not enough for a driveway base. Driveways typically require several inches of compacted fill plus a compacted aggregate base (often 4 to 8 inches total) depending on load. For vehicle traffic in O'Fallon, build a stable, well-compacted subgrade and a crushed stone base rather than relying on thin layers of fill dirt alone.

Fill dirt can be used to bring grades up under a patio but should be free of organic material and well compacted. For the structural base under pavers or concrete, crushed stone or compacted aggregate is preferred to ensure drainage and stability. If you use fill dirt for bulk fill, follow with a compacted aggregate base before building the patio surface.

A typical tri-axle dump truck used by Hello Gravel haulers carries roughly 10 to 14 cubic yards, which converts to about 13 to 18 tons depending on moisture and soil type. Cost depends on material, volume, and delivery distance; request a quote for an exact delivered price to O'Fallon. Remember our minimum order is 3 tons and delivery timing is usually 2+ business days with a next-day option.

No, compacted fill dirt becomes firm but does not harden like concrete. It gains stability when properly placed in layers and compacted, but it will still be affected by moisture and freeze-thaw cycles in the St. Louis region. For a permanent, hard surface consider concrete, asphalt, or a compacted crushed-stone base instead of relying solely on fill dirt.

O'Fallon and the St. Louis area commonly have silt-loam and clay-influenced soils, and wet springs can increase settling if fill is not compacted properly. Freeze-thaw cycles can also lead to movement, so contractors often compact fill in lifts and design slopes for drainage away from structures. When in doubt, consult Hello Gravel or a local contractor about the right fill type and compaction for your project.
