Limestone Screenings for Pathways in Arion, IA

Iowa Rock Supply brings gravel and aggregate delivery in Arion, IA, with Class A roadstone as the base course this part of Crawford County builds on. The ground here is old till under a loess cap, and the clay beneath it holds water.

That shapes what you order: a base that binds, screenings that bed a path, and clean stone where water has to move.

Ground and Conditions in Arion

Across the Southern Iowa Drift Plain, the subsoil is a gummy grey clay that water will not pass through. Rain perches on it, runs off, and leaves a drive soft at the bottom of a grade.

A thin base is the first thing to show it. The stone punches down into the soft clay, ruts appear, and the surface never tightens up.

The fix is a compacted roadstone course that spreads the load instead of sinking into it. Class A roadstone is crushed limestone with the fines left in, so it binds and compacts into a firm layer.

This is also Iowa's most eroded landscape. Streams cut deep, hillslopes carry fine rills, and gullies open after heavy rain on saturated clay.

That is why rock goes in on slopes and at culvert outlets. Riprap armors a bank or a pond edge where spring runoff would otherwise cut it away.

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

Freeze and thaw heaves gravel drives and lanes every spring. Frost depth in this zone is commonly 42 inches, and the local building official sets footing depth.

Limestone screenings are the fines left after crushing, sold as 3/8 inch minus. They pack tight under pavers and flagstone and fill the joints between them.

Screenings also make a fine top dressing over a compacted roadstone base, which is how a garden path or walkway gets a smooth, walkable surface.

For a path that wants a looser finish, Walkway Gravel gives a finer surface than drive rock. Natural Pea Gravel is another option for walkways and small drainage runs.

Under any of it, Class A Roadstone is the compacted base for drives, parking pads, shed bases and farm lanes.

Where a new drive or a soft spot needs a coarser start, 1 Inch Roadstone goes down first, then a finer surface course over it.

Water has to go somewhere. Clean Rock is washed and open graded, so it moves water straight through for subdrains, pipe bedding and retaining wall backfill.

For a drive surface that stays free draining, or for trench backfill, 3/4" Crushed Stone is the clean, open stone to order.

On the decorative side, River Rock is rounded gravel washed out of the Missouri, Mississippi and their tributary valleys. It suits beds, borders and dry creek beds.

Questions About Ordering

What should I have ready when the truck arrives?

Have the drop spot clear of vehicles, trailers and low branches, and firm enough that a loaded truck can reach it. The driver tips the load in one pile, so leave room for it and keep the area open.

If the ground is soft from spring rain, pick a spot that will hold the weight.

What is the best base under pavers in Arion?

Class A roadstone is the base course for this ground, because the crushed limestone with fines left in binds and compacts into a firm layer over clay. Limestone screenings then bed the pavers and fill the joints.

On the Southern Iowa Drift Plain, that compacted base keeps the surface from punching into soft subsoil.
