Buy Fill Dirt in Defiance, IA

Iowa Rock Supply brings gravel and aggregate delivery in Defiance, IA to contractors and homeowners working on the same short list of jobs: a drive that has gone soft, a yard that needs grading, a bed that needs soil, a lane that needs a base course.

Class A roadstone is the crushed limestone base this part of Iowa builds on, and it is where most of those jobs start. So is fill dirt, black dirt and garden soil, which is what this page leads with.

Materials for Defiance Projects

Grading and bed prep come first, because nothing else sits right until the ground under it is at the right level. Fill dirt raises low ground and backfills a cut before a base course goes down.

Screened black dirt, which Iowa yards call black dirt, dresses up a lawn or a bed after the grade is set.

Garden soil is blended richer than plain black dirt for raised beds and vegetable plots. Both are sold by the ton or the yard, and each product page has a calculator.

Under a drive or a farm lane, Class A Roadstone is the standard base course. It is crushed limestone with the fines left in, so it binds and compacts.

Where a lane carries heavy equipment or a soft spot needs a coarser start, 1 Inch Roadstone goes down first.

For water, Clean Rock is washed and open graded, so it moves water instead of holding it. Use it for subdrains, pipe bedding and backfill behind a retaining wall.

Sand and decorative stone round out a project. Washed Sand beds and levels under slabs and pavers, and River Rock covers a bed or a dry creek bed with rounded gravel washed out of the Missouri and Mississippi valleys.

Ground and Conditions in Defiance

Across the Southern Iowa Drift Plain, rain, snowmelt and spring storms are the whole story. The ground is steeply rolling, so water runs off at the surface, but the clay subsoil underneath does not take it in.

That water perches, then runs downhill, and it leaves drives soft at the bottom of a grade. Spring rain on saturated clay is the worst of it.

The region also erodes hard. Streams cut deep, hillslopes carry a fine texture of rills, and gully and stream bank erosion after heavy rain is the main reason rock goes in on slopes and at culvert outlets.

That is where Riprap earns its place, armoring a bank or a pond edge against runoff.

Clay soils also need to dry before anything gets compacted. A wet spring can push base work back several weeks, even in the longest working season in the state.

Winters bring repeated freeze and thaw, which heaves gravel drives and lanes every spring. Footing depth is set by the local building official, so check with that office before you pour.
