Order Class A Roadstone and Crushed Stone in Greene County, IA
Iowa Rock Supply handles gravel, stone and aggregate delivery in Greene County, IA. If you are building a drive, a parking pad or a shed base, the material under it decides how the job holds up.
Class A roadstone is the crushed limestone base course with the fines left in, so it binds and compacts. It is the standard Iowa base course, and it is where most ground work here starts.

Class A roadstone, also called roadstone or 3/4 inch roadstone, is the crushed limestone base for driveways, parking pads, shed bases and farm lanes.
11. County engineers and city entrance standards call the same material roadstone and write it as Class A roadstone.
When you need a coarser grade, 1 Inch Roadstone goes down first for a new drive, a soft spot or a lane that carries heavy equipment. It sits under a finer surface course.
For bedding and joints, Limestone Screenings bed pavers and flagstone, fill joints and dress the top of a compacted roadstone base. Where water has to move, Clean Rock is washed and open graded, so it drains through subdrains, drainage tile backfill, pipe bedding and the backfill behind retaining walls.
Sand and soil round out a job. Mason Sand goes into brick and block mortar, paver joints and horse arena footing, and Washed Sand beds and levels under slabs and pavers.
Iowa yards call screened topsoil black dirt, after the dark prairie soils the state is known for, and Top Soil is what lawn repair, grading and bed prep take.
Choosing the right material
Greene County sits on the Des Moines Lobe, the youngest glacial ground in Iowa: thick, compact pebbly loam till of the Dows Formation, 45 to 60 feet deep, with sand and gravel along old meltwater channels and hummocky, stony ground on the moraine ridges.
Boone County and Calhoun County sit on the same Des Moines Lobe ground, so the base and drainage choices there work the same way they do here.
Guthrie County is different. It spans more than one zone and takes in the Southern Iowa Drift Plain as well as the Des Moines Lobe.
Older drift ground like that is generally less pebbly and better drained than the fresh till here, so a base that sheds water in Guthrie County may sit wetter on the Lobe side.
On this ground, a thin base is the failure you plan around. Water sits where the ground below is still frozen, and a drive or pad over too little stone ruts and pumps in spring.
A compacted roadstone course spreads that load instead of letting it work into the till.
Ground conditions across Greene County
This is pothole country. The drainage network is young and inefficient, kettles and closed depressions hold water, and most of the ground only drains at all because it is tiled.
Snowmelt and spring rain sit on the surface where the ground below is still frozen.
That changes what a base has to do. A fines-bearing roadstone binds and compacts into a firm course, while clean, open graded stone is the layer that lets water move.
Where a low spot or a tile outlet stays wet, drainage stone belongs in the design.
Erosion here is less about slope and more about concentrated flow: ditch and tile outlet scour, bank cutting on the Des Moines, Boone and Iowa rivers, and washouts on the moraine ridges. Riprap armor is the answer at culvert outlets, pond edges and any bank taking spring runoff.
Compaction waits for the frost to come out and for the flat ground to shed its spring water. Base and paver work runs from late spring to the fall freeze, and a wet spring shortens that window.
Long, cold winters bring repeated freeze-thaw that heaves gravel drives, lanes and field entrances as the ground lets go. Frost depth is commonly 42 inches, and the local building official sets footing depth.
