Austinville sits in Butler County on the Iowan Surface, where the ground is loamy glacial till with a thin, patchy cover of loess over it.

Materials for Austinville Projects

This part of Iowa has long, low slopes and slow, shallow drainage, so a lot of work here begins with coarse stone. Coarse, angular material is what holds a slope, lines a swale, or armors a bank where runoff concentrates.

Start with the big sizes and work down.

Riprap

Riprap is the coarsest material on the yard, also sold as revetment stone or Class D and Class E revetment. It armors stream banks, culvert outlets, pond edges and slopes against spring runoff.

If a bank is cutting, this is the stone that holds it.

1 Inch Roadstone

1 Inch Roadstone, or 1 inch minus, is the coarser roadstone. It goes down on a new drive, a soft spot, or a lane that carries heavy equipment, under a finer surface course.

The fines are left in so it binds and compacts.

Class A Roadstone

Class A Roadstone is the standard Iowa base course, 3/4 inch crushed limestone with the fines left in. Driveways, parking pads, shed bases and farm lanes all ride on it.

Clean Rock

Clean Rock, also called clean stone or 1 inch clean, is washed and open graded, so water moves straight through it. It suits subdrains, drainage tile backfill, pipe bedding, septic rock and the backfill behind a retaining wall.

Limestone Screenings

Limestone Screenings are the fine end, sold as screenings or 3/8 inch minus. They bed pavers and flagstone, fill joints, and top dress over a compacted roadstone base.

Delivery to Austinville and the Surrounding Area

Iowa Rock Supply covers Austinville and the rest of Butler County, including Parkersburg, Shell Rock, Clarksville, Greene and Allison. You order online, pick your quantity by the ton or the yard, and choose a delivery date at checkout.

A dump truck then tips the load on your site.

Where the truck can reach matters more than anything else on delivery day. A drive or lane that will carry a loaded truck needs a firm, compacted surface, and that is where Class A roadstone earns its place before the delivery is even scheduled.

Ground and Conditions in Austinville

Across the Iowan Surface, work starts once frost is out and the low gradient ground has drained, and it runs to the fall freeze. Low spots stay soft well after the uplands are ready, so timing a delivery around that matters.

The drainage network here is well established, but stream gradients are low, so water moves slowly. Pockets of old wetland ground still hold water, and limestone aquifers can put groundwater close to the surface.

That is why a clean, open graded stone belongs in a drainage run rather than a fines-bearing one.

Erosion follows the same pattern: sheet wash on the long, low slopes, gully cutting where runoff concentrates, and bank scour after heavy rain and thaw. Coarse stone at those points does the work.

Northern Iowa also gets a long frozen season and repeated freeze-thaw, which lifts gravel drives, walks and slabs each spring. Footing depth is commonly 42 inches on the Iowan Surface, and the local building official sets the figure that applies to your project.

Questions Austinville Buyers Ask

What stone should I use for drainage in Austinville?

Use clean, open graded stone so water passes through instead of sitting in it. Clean Rock at 1 inch, or 3/4 inch clean stone, suits subdrains, pipe bedding and trench backfill.

For heavy drainage, construction entrances and trench bottoms, #4 crushed stone is the larger option. Limestone screenings and Class A roadstone both carry fines, so they belong under a base or in a joint, not in a drain.

What should I have ready when the truck arrives?

Have a clear, firm route to the spot where the pile should land. A dump truck tips the load in one pile, so the ground under it needs to carry the weight without rutting.

If your drive is thin or soft, Class A roadstone over the existing surface gives the truck something to roll on before the material is tipped.
