Gravel, Stone and Soil for Keokuk County, IA
If you are planning a driveway, a patio base or a drainage run, you need gravel, stone and aggregate delivery in Keokuk County, IA. Iowa Rock Supply sells bulk material online and tips it on site.
Start with Class A roadstone, the crushed limestone base course Iowa calls roadstone. It has the fines left in, so it binds and compacts under a drive, a parking pad or a farm lane.
Materials Delivered in Keokuk County
Class A roadstone is the base course for drives, parking pads, shed bases and farm lanes.
11. County engineers and city entrance standards write the same material as Class A roadstone.
When you need a coarser grade, 1 Inch Roadstone goes down first on a new drive or a lane that carries heavy equipment. Limestone Screenings bed pavers and flagstone and fill the joints between them.
For water that has to move, Clean Rock is washed and open graded, so it suits subdrains, pipe bedding and backfill behind a retaining wall. 3/8" Crushed Stone is sold as washed chips and works as seal coat aggregate and fine drainage.
On slopes and outlets, Riprap armors a stream bank, a culvert outlet or a pond edge against runoff. Top Soil covers lawn repair and bed prep, and Washed Sand beds and levels under slabs and pavers.

Ground Conditions Across Keokuk County
Across the Southern Iowa Drift Plain, old pre-Illinoian till sits under a windblown loess mantle, usually 5 to 30 feet thick. Beneath it is the Yarmouth-Sangamon paleosol, a thick, gummy grey clay that water will not move through.
Farmers call working in it gumbo.
That clay is why a thin base shows its failure first. The ground rolls steeply and drains at the surface, but the subsoil does not take water, so it perches and runs off.
Drives go soft at the bottom of a grade, and spring rain on saturated clay is the worst of it.
This is Iowa's most eroded landscape. Streams cut deeply, hillslopes carry a fine texture of rills, and gully and stream bank erosion after heavy rain is the main reason rock goes in on slopes and at outlets.
The working season here is the longest in the state, but clay soils need to dry before anything gets compacted. A wet spring pushes base work back several weeks.
Cold winters bring repeated freeze-thaw, milder than the north but still enough to heave gravel drives and lanes every spring. Frost depth is commonly 42 inches, and the local building official sets footing depth.
Choosing the Right Material
Wapello County, Washington County and Mahaska County all sit on the same Southern Iowa Drift Plain ground as Keokuk County. The till, the loess mantle and the gummy grey clay below are the same, so the base and drainage choices are the same too.
Match the material to the job. A compacted base wants Class A roadstone, because the fines bind it together.
A drainage run wants clean, open graded stone instead, because water has to pass through rather than sit.
Where runoff crosses a slope or leaves a culvert, riprap holds the ground in place. Where you are bedding pavers or filling joints, screenings or washed sand do the fine work.
