Bulk Gravel Delivery to Exira, IA

Planning gravel and aggregate delivery in Exira, IA usually starts with one job: a drive that has gone soft, a patio base, or a drainage run that will not dry out. Iowa Rock Supply delivers bulk material across Audubon County.

Most of that work starts with Class A roadstone, the crushed limestone base course this part of Iowa builds on. You order online by the ton or the yard and a dump truck tips the load on site.

Ground and Conditions in Exira

Across the Southern Iowa Drift Plain, the ground is old till under a windblown loess mantle. Under both sits a thick, gummy grey clay that water will not move through.

Farmers working it call it gumbo.

That clay is why a thin base fails here. Water perches on the clay, runs off the slope and leaves the bottom of a grade soft and rutted.

Spring rain on saturated clay is the worst of it.

This is also the state's most eroded landscape. 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 outlets.

The working season here is the longest in the state, but clay soils need to dry before anything gets compacted. A wet spring pushes base work back several weeks.

Cold winters bring repeated freeze and thaw, milder than northern Iowa but still enough to heave gravel drives and lanes every spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.

A soft spot is a drainage problem before it is a stone problem. Open graded clean rock under a fines-bearing surface gives perched water somewhere to go.

Materials for Exira Projects

Fines and screenings do the finish work on paths and walkways, and they are where a lot of projects here run into trouble.

Limestone screenings, sold locally as screenings or 3/8 inch minus screenings, are the fine crushed limestone used for paver and flagstone bedding, joint filling and a top dressing over a compacted roadstone base. On a garden path they give you a surface that packs and stays walkable.

For the base under that path or drive, Class A roadstone is the standard Iowa base course: 3/4 inch crushed limestone with the fines left in, so it binds and compacts. It goes under driveways, parking pads, shed bases and farm lanes.

Class A Roadstone is the material to start with when you are building up a grade.

Where the ground is coarse or the drive is new, 1 Inch Roadstone is the coarser grade. It is laid under a finer surface course on a new drive, a soft spot or a lane that carries heavy equipment.

Walkways that want a finer, walkable surface than drive rock take Walkway Gravel. For a looser, free draining surface, 3/4" Crushed Stone is washed and open graded, so water moves straight through it.

Questions About Gravel and Stone in Exira

What should I have ready when the truck arrives?

Have the drop area clear and reachable, with no parked vehicles, low wires or soft ground in the way. The truck tips the load in one pile, so the spot you choose is where the material stays.

Marking the edge of a drive or pad helps you see where the pile lands.

What is the best base under pavers in Exira?

Class A roadstone is the base course to build on, because the fines left in the crushed limestone let it bind and compact. Over that clay subsoil, a clean open graded stone below the base gives perched water a path away.

Limestone screenings then bed the pavers and fill the joints.
