What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone is angular, broken limestone with sharp edges, and the fines left in a roadstone grade let it bind and compact. Natural Pea Gravel is rounded and washed, roughly 3/8 inch, and it stays loose. That makes Natural Pea Gravel good for walkways, play areas and patio bedding, while crushed stone is what you want under a drive or pad.

Should I order material by the ton or by the yard?

Both work. Iowa Rock Supply takes orders by the ton or by the yard, so pick whichever unit you already have. If you are not sure how much you need, each product page has a calculator you can use to size the load before you check out.

Which stone is best for drainage in Kossuth County?

Clean rock is the right choice for drainage here. It is washed and open graded, so water moves straight through instead of sitting, which suits subdrains, pipe bedding and septic rock in this pothole country. For finer drainage and paver joints, washed chips work well.

Class A roadstone is the crushed limestone base course most drives, pads and farm lanes start from here.

This is pothole country on the Des Moines Lobe, where the ground drains poorly and spring water sits on top of still frozen soil. That shapes what you order and when you take it.

Ground Conditions Across Kossuth County

Across the Des Moines Lobe, the ground is thick, compact pebbly loam till of the Dows Formation, running 45 to 60 feet deep. 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.

That matters for a base. A compacted roadstone course needs ground that has let go of its water, and a wet spring shortens the window for that work.

Erosion here is less about slope and more about concentrated runoff. Ditch and tile outlet scour, bank cutting on the rivers, and washouts where runoff gathers on the moraine ridges are the common problems.

Compaction waits for frost to leave the ground and for flat ground to shed its spring water. Base and paver work runs from late spring to the fall freeze.

Winters are long and cold, with repeated freeze and 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 Kossuth County

Material is ordered by size and by what it does. Class A roadstone is the standard Iowa base course: 3/4 inch crushed limestone with the fines left in, so it binds and compacts.

10. County engineers and city entrance standards call the same material Class A roadstone.

Order Class A Roadstone for driveways, parking pads, shed bases and farm lanes. Use 1 Inch Roadstone for a new drive, a soft spot, or a lane that carries heavy equipment.

For drainage, 3/8" Crushed Stone is the washed chip Iowa quarries sell for seal coat, paver joints and fine drainage. 3/8" Natural Pea Gravel suits walkways and play areas.

Choosing the Right Material

Wright County, Hancock County and Winnebago County all share the same ground region as Kossuth County. The youngest glacial ground in Iowa is the same on all sides: thick pebbly loam till over sand and gravel along old meltwater channels.

Because the ground is the same, the base and drainage choices are the same. There is no ground difference to work around between these counties.

Pick by what the material has to do. A compacted base wants roadstone with fines left in.

A drainage run wants clean, open graded stone, because fines block water movement.

Decorative and bedding work is a separate decision. Rounded river rock and Natural Pea Gravel stay loose, so they suit beds and walkways rather than a load-bearing base.
