Boone County, IA Gravel and Landscape Rock Delivery
Iowa Rock Supply brings gravel, stone and aggregate delivery in Boone County, IA to driveways, farm lanes and building pads. Start with Class A roadstone, the crushed limestone base this part of the state builds on.
Across the Des Moines Lobe, the ground is young glacial till that holds water and moves when it thaws. The right stone underneath is what keeps a drive or a pad where you put it.
Ground conditions across Boone County
Boone County sits on the Des Moines Lobe, the youngest glacial ground in Iowa. Under the topsoil is thick, compact pebbly loam till of the Dows Formation, running 45 to 60 feet deep.
That till is dense and slow to drain. Sand and gravel sit along old meltwater channels, and the moraine ridges are hummocky and stony.
This is pothole country. The drainage network is young and inefficient, kettles and closed depressions hold water, and most ground only drains because it is tiled.
Snowmelt and spring rain sit on the surface where the ground below is still frozen. A base laid on that ground without enough stone will pump and rut.
Erosion here is less about slope and more about concentration. Ditch and tile outlet scour, bank cutting on the Des Moines, Boone and Iowa rivers, and washouts where runoff gathers on the moraine ridges.
Compaction waits for the frost to come out and 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.
Winters are long and cold, with repeated freeze-thaw that heaves gravel drives, lanes and field entrances as the ground lets go in spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
Materials delivered in Boone County
Order by project. A driveway, a patio and a drain each want a different stone, and the local names below are what Iowa quarries and crews use.
Class A roadstone carries the most weight in this county. It is the standard Iowa base course: 3/4 inch crushed limestone with the fines left in, so it binds and compacts under a drive, a parking pad or a farm lane.
That section defines Class A crushed stone and Class B crushed stone to Gradation No.
11 and Class C gravel to Gradation No. 10.
County engineers and city entrance standards call the same material roadstone and write it as Class A roadstone. Section 4130 covers revetment stone, erosion stone and gabion stone by class letter, and Section 4123 covers modified subbase.
For a new drive or a lane that carries heavy equipment, 1 Inch Roadstone goes down first as a coarser course. It handles a soft spot better than a fine material.
Where water has to leave, use Clean Rock for subdrains, drainage tile backfill, pipe bedding and behind retaining walls. It is washed and open graded, so it will not hold water.
Limestone Screenings bed pavers and flagstone and fill the joints. Riprap, sold locally as revetment stone, armors stream banks, culvert outlets and pond edges against spring runoff.
For beds and lawns, Top Soil is the screened black dirt Iowa yards ask for by name. Washed Sand beds and levels under slabs and pavers.
Choosing the right material
Boone County shares its ground region with Polk County and Greene County, both on the Des Moines Lobe. The soil story is the same across all three: thick Dows Formation till, young drainage, and water that sits.
Dallas County is the one that differs. It spans more than one zone, sitting on the Des Moines Lobe and the Southern Iowa Drift Plain.
That difference matters at the base. Ground that crosses into older, better drained drift sheds water differently than the tight lobe till here, so a base course and a drainage layer get planned against different conditions.
Within Boone County, match the stone to the job. A driveway wants Class A roadstone for the base and a finer surface course on top.
A patio wants screenings for bedding and washed sand for leveling. A drain, a septic line or a retaining wall wants clean, open graded stone that water passes through.
Bank work on a river or a pond edge wants riprap sized for the flow it faces.
