Can I order material for a commercial or contractor job?

Yes. Order online by the ton or by the yard for commercial and contractor work, the same as for a residential drive or pad. Class A roadstone, clean rock, riprap and the rest of the aggregate line are all ordered the same way. Pick your delivery date at checkout and a dump truck tips the load on site.

What is the difference between topsoil and fill dirt?

Topsoil is screened black dirt, the dark prairie soil Iowa yards use for lawn repair, grading and bed prep. Fill dirt is unscreened material for raising grade, filling low ground and backfilling before a roadstone course goes down. Use topsoil where plants grow and fill dirt where you need volume.

Winnebago County, IA Aggregate and Rock Delivery

Iowa Rock Supply delivers gravel, stone and aggregate delivery in Winnebago County, IA, ordered online and tipped on site by dump truck. Class A roadstone is the base course to start with here, the crushed limestone that binds and compacts under a drive or a pad.

Winnebago County sits on the Des Moines Lobe, the youngest glacial ground in Iowa, where thick pebbly loam till and young drainage shape how a base has to be built.

Materials Delivered in Winnebago County

Class A roadstone is the standard Iowa base course: 3/4 inch crushed limestone with the fines left in, so it binds and compacts. In Iowa, and county engineers write the same material as Class A roadstone.

Order it for driveways, parking pads, shed bases and farm lanes. A coarser grade, 1 Inch Roadstone, goes under a finer surface course on a new drive, a soft spot or a lane that carries heavy equipment.

Washed, open graded material is clean rock here, and water moves straight through it. Use Clean Rock for subdrains, drainage tile backfill, pipe bedding and septic rock.

Choosing the Right Material

Kossuth County and Hancock County sit on the same Des Moines Lobe ground as Winnebago County: thick pebbly loam till over sand and gravel along old meltwater channels. The base and drainage choices are the same there.

Worth County spans more than one ground region, reaching onto the Iowan Surface as well as the Des Moines Lobe. Where the ground is older and less pebbly, drainage behaves differently, and a clean open graded stone matters more than a fines-bearing base.

Match the material to the job. Roadstone binds and compacts for a base.

Clean rock drains. Screenings bed pavers.

Riprap holds a bank against runoff.

Ground Conditions Across Winnebago 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. A thin base over that ground pumps and breaks up, so the fix is a compacted roadstone course that carries the load.

Slope erosion is lighter here than in much of the state, but ditch and tile outlet scour, bank cutting and washouts where runoff concentrates on the moraine ridges are the real exposure. Riprap and clean rock handle those spots.

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.
