Buy Fill Dirt in Shelby, IA

Iowa Rock Supply handles gravel and aggregate delivery in Shelby, IA for grading, bed prep and drive work. If you are raising a low spot in a yard or rebuilding a lane, you will want fill dirt under the surface and Class A roadstone on top of it.

On the Southern Iowa Drift Plain, that dark prairie soil is why so much of the work here starts with black dirt and garden soil before any stone goes down.

Materials for Shelby Projects

Grading and bed prep are where most Shelby projects begin, and that means soil and fill first. Which one you want depends on whether you are feeding plants or building up ground.

Top Soil is screened black dirt, the dark prairie soil Iowa yards are known for. Use it for lawn repair, grading and bed prep.

Garden Soil is a richer blend for raised beds, vegetable gardens and planting areas.

Fill Dirt is the structural side of the same job. It raises grade, fills low ground and backfills before a roadstone course goes down.

Once the grade is set, the base materials take over. Class A Roadstone is 3/4 inch crushed limestone with the fines left in, so it binds and compacts.

It is the standard base for driveways, parking pads, shed bases and farm lanes.

1 Inch Roadstone is the coarser grade, laid under a finer surface course on a new drive, a soft spot or a lane that carries heavy equipment.

For wet ground, washed stone moves water rather than holding it. Clean Rock is washed and open graded, so it goes into subdrains, drainage tile backfill, pipe bedding and behind retaining walls.

Decorative and finishing materials round out a yard. River Rock is rounded gravel washed out of the Missouri and Mississippi valleys, used in beds, borders and dry creek beds.

Washed Sand beds and levels under slabs and pavers, and Shredded Mulch holds moisture through a dry Iowa August.

Ground and Conditions in Shelby

Water is the driver on this ground. Across the Southern Iowa Drift Plain the surface rolls and drains, but the clay subsoil underneath does not take water, so it perches and runs off.

That leaves drives and lanes soft at the bottom of a grade, and spring rain on saturated clay is the worst of it.

The subsoil here is old pre-Illinoian till under a windblown loess mantle, with a thick gummy grey clay layer beneath. Farmers call working in it gumbo.

It does not drain and it does not like to compact while it is wet.

This is also Iowa's most eroded landscape. Streams cut deep, 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 culvert outlets.

Cold winters bring repeated freeze-thaw, enough to heave gravel drives and lanes every spring. Frost depth in much of Iowa is commonly 42 inches, and the local building official sets footing depth for structures.

The working season here is the longest in the state, but clay soils need to dry before anything gets compacted. A wet spring can push base work back several weeks.
