Fill Dirt in Affton, MO

Typical delivered prices for basic fill-dirt in the Affton/West Missouri area usually fall in a broad range because of local sourcing and truck distance. Expect ballpark pricing around $12 to $30 per ton delivered for most residential orders, with minimum orders usually 3 tons; exact pricing depends on your zip code, access, and supplier.

For raising yard grade or backfilling in Affton's clay-prone soils, use well-graded fill-dirt with a mix of fines and mineral particles that compact well, sometimes called compactable or structural fill. Avoid loose, high-organic topsoil as a base under driveways or foundation areas; for driveway bases, pair compacted fill-dirt with a layer of crusher run or crushed stone to improve drainage and load-bearing. If your project is structural (foundation, retaining walls), check with an engineer about engineered structural fill.

Affton experiences seasonal freeze-thaw cycles and fairly wet springs, which can increase settling and frost heave if the fill is not compacted and drained properly. Compact fill-dirt in 4- to 8-inch lifts with a plate compactor or roller and provide positive surface drainage to reduce water infiltration. Expect some additional settling in the first 6 to 12 months and plan to regrade or add material if needed.

One cubic yard of material covers 324 square feet at 1 inch depth, so calculate cubic yards as (square feet x inches of fill) / 324. As a rule of thumb, loose fill-dirt in this region weighs about 1.1 to 1.3 tons per cubic yard; multiply cubic yards by your local tons-per-yard estimate to convert to tons. For example, a 200 sq ft area raised 6 inches needs about (200 x 6) / 324 = 3.7 cubic yards, roughly 4.1 to 4.8 tons.

Permit and setback rules depend on local and county regulations; Affton is in St. Louis County, so larger grading projects, changes to drainage, or work near floodplains and wetlands may require permits or engineering review. Small residential fills under a certain volume are often allowed without a permit, but you should check St. Louis County or municipal rules before major grading. When in doubt, contact county permitting and consult Hello Gravel if you need help estimating volumes before you talk to authorities.

Use fill-dirt to raise grade where structural strength is not the final surface; it is economical for bulk raising but can hold moisture and is not a good wearing surface. For driveways, use compacted fill-dirt as a bulk lift if needed, then cap with crusher run or crushed stone for compaction and drainage. For lawns and planting beds, topsoil or a topsoil cap over compacted fill is recommended to support vegetation.

A properly compacted and drained fill-dirt area can be stable for years, but expect some settlement during the first 6 to 12 months, especially after wet seasons in Missouri. Plan to monitor and add material or regrade low spots after major rain or seasonal thaw, and keep surface drainage directed away from foundations and neighbors. For vegetated areas, cap with topsoil and seed or sod; for traffic areas, use a stone cap and periodic regrading as needed.

At checkout, include your preferred delivery date, any access notes (narrow driveways, overhead wires, gate codes), and if you want the driver to consider tailgate spreading; drivers may spread at their discretion but it is not guaranteed.
