Order Gravel, Stone and Soil in Audubon, IA

Iowa Rock Supply handles gravel and aggregate delivery in Audubon, IA, and every load starts with a quantity. Each product page has a calculator, so you size the load before you order.

Class A roadstone is the crushed limestone base this part of Iowa builds on.

The Southern Iowa Drift Plain sits under a windblown loess mantle here, and that ground shapes what you put on top of it.

Delivery to Audubon and the Surrounding Area

You order online and pick a quantity by the ton or by the yard. Choose a delivery date at checkout, and a dump truck tips the load in one pile at your site.

Audubon sits in Audubon County, and delivery reaches Exira, Kimballton, Brayton and Hamlin as well. A driveway, a shed pad, a garden bed and a farm lane all arrive the same way: one truck, one pile, tipped where you want it.

Materials for Audubon Projects

Decorative work is where a lot of Audubon ground gets finished, and the beds, borders and dry creek beds around a yard take materials that behave differently from a drive. River rock is rounded gravel washed out of the Missouri, Mississippi and their tributary valleys, and it suits decorative beds and borders.

Large river rock is the oversized version, used for dry creek beds, splash pads and heavier bank work. Natural Pea Gravel, which Iowa calls Natural Pea Gravel rather than pea stone, covers walkways, play areas and patio bedding.

Under all of that, the structural materials do the load bearing. Class A roadstone is the standard base course, crushed limestone with the fines left in so it binds and compacts, and it goes under driveways, parking pads, shed bases and farm lanes.

Where you want a loose, free draining surface instead, 3/4 inch clean stone is washed and open graded, so water moves straight through it. Limestone screenings bed pavers and flagstone and fill joints.

For a patio, screenings bed the pavers and washed sand levels under slabs. For a drain, clean rock is washed and open graded so water passes through it.

For a drive, roadstone is the base and driveway rock tops a lane that has thinned out.

Around the edges of a project, black dirt handles lawn repair, grading and bed prep, and shredded hardwood mulch holds moisture in beds and tree rings through a dry Iowa August.

Ground and Conditions in Audubon

Across the Southern Iowa Drift Plain, old pre-Illinoian till sits under a windblown loess mantle. Beneath that is a thick, gummy grey clay that water will not move through, and farmers call working in it gumbo.

That clay is the reason a base gets built the way it does here. The ground drains at the surface but the subsoil does not take water, so it perches and runs off, and drives go soft at the bottom of a grade.

This is Iowa's most eroded landscape. Streams cut deeply, 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 outlets.

Riprap armors a stream bank, a culvert outlet or a pond edge against that runoff.

Timing matters too. This part of the state has the longest working season in Iowa, but clay soils need to dry before anything gets compacted, so a wet spring pushes base work back several weeks.
