Carroll County, IA Gravel and Landscape Rock Delivery
Iowa Rock Supply handles gravel, stone and aggregate delivery in Carroll County, IA. Size the load on the calculator first, then pick the material.
Class A roadstone is the base course most ground here wants, and the rest of the list is drive rock, drainage stone, sand, black dirt and mulch.
This county sits on two different kinds of ground, and that changes what you put under a drive or a pad. The material list below is built around those differences.

Materials delivered in Carroll County
Lead with the job. A driveway wants a roadstone base and a topping.
A patio wants bedding and joint material. A drain wants washed, open graded stone.
Match the material to the work and the rest follows.
Driveways, lanes and pads
Class A Roadstone is the standard base here. It is crushed limestone with the fines left in, so it binds and compacts.
County engineers and city entrance standards write it the same way.
For a new drive, a soft spot or a lane carrying heavy equipment, start with 1 Inch Roadstone, the coarser grade, then bring a finer course over the top. Where an existing drive has thinned out, Driveway Gravel refreshes the surface.
Drainage and water
Clean Rock is washed and open graded, so water moves straight through it. It goes in subdrains, drainage tile backfill, pipe bedding, septic rock and behind retaining walls.
3/4" Crushed Stone does the same work at a finer size and surfaces a drive that wants a loose, free draining top.
#57 Stone suits drainage runs and subdrain backfill. Iowa concrete stone gradations are written D57 and D67.
Riprap, sold as revetment stone under Section 4130, armors stream banks, culvert outlets and pond edges.
Bedding, paths and finishes
Limestone Screenings bed pavers and flagstone, fill joints and dress the top of a compacted roadstone base. Mason Sand mixes into brick and block mortar and fills paver joints, and Washed Sand beds and levels under slabs and pavers.
For the soft side of the yard, Top Soil is the screened black dirt Iowa yards ask for, and Shredded Mulch holds moisture through a dry August. 3/8" Natural Pea Gravel covers walkways and play areas.
Ground conditions across Carroll County
Carroll, Glidden, Arcadia and Breda sit on Des Moines Lobe ground. That is thick, pebbly loam till 45 to 60 feet deep, with sand and gravel along old meltwater channels and stony ridges on the moraines.
It is the youngest glacial ground in the state.
Manning, Coon Rapids, Templeton and Dedham sit on the Southern Iowa Drift Plain instead. Old till lies under a windblown loess mantle, usually 5 to 30 feet thick, with buried paleosols beneath.
The Yarmouth-Sangamon paleosol is a gummy grey clay that water will not move through.
Des Moines Lobe ground drains poorly. Kettles and closed depressions hold water, snowmelt sits where the ground below is still frozen, and most of it only drains because it is tiled.
An under-built base there softens fast in spring.
On Drift Plain ground the surface drains but the clay subsoil does not. Water perches, runs off and leaves drives soft at the bottom of a grade.
Spring rain on saturated clay is the worst of it.
Erosion follows the same split. Des Moines Lobe ground sees ditch and tile outlet scour and washouts where runoff concentrates.
The Drift Plain is the state's most eroded landscape, with deep streams, rills on the slopes, and gully cutting after heavy rain.
Freeze-thaw heaves gravel drives, lanes and field entrances every spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
Compaction waits for frost to leave and for flat ground to shed spring water. On Drift Plain clay, a wet spring pushes base work back several weeks.
Choosing the right material
Crawford and Shelby counties both sit on Southern Iowa Drift Plain ground, the same old till under loess that Manning and Coon Rapids sit on.
The ground there is the same, and the base and drainage choices follow the same logic: a compacted roadstone base over ground that will not take water, with clean stone where water has to move.
Guthrie County spans two zones, Southern Iowa Drift Plain and Des Moines Lobe. That is the same pair Carroll County straddles, so the ground and the material choices carry across.
Match the material to the ground under it. On heavy till or gummy clay, the base course does the work and clean stone handles the water.
Questions about ordering in Carroll County
Which stone is best for drainage in Carroll County?
Clean rock is the one. It is washed and open graded, so water passes through instead of sitting in it, which suits both the Des Moines Lobe ground and the clay subsoil on the Drift Plain.
Use it in subdrains, pipe bedding and behind retaining walls. 3/4 inch clean stone, #57 stone and #4 crushed stone all do drainage work at different sizes.
What do I need to have ready for a bulk delivery?
Have the drop spot clear and reachable before the truck arrives. The truck tips the load in one pile, so the space needs to be open enough for that.
Choose your quantity by the ton or by the yard when you order, use the calculator to size the load, and pick a delivery date at checkout.
What is the best base material for a patio in Carroll County?
Class A roadstone is the base, the same Class A crushed stone that Section 4120 specifies locally. It is crushed limestone with the fines left in, so it binds and compacts rather than shifting.
Limestone screenings bed the pavers over that base, and washed sand levels under slabs. On Drift Plain clay, the base matters most.
