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. Fill dirt is structural; topsoil is what plants grow in. Use fill to build the grade and topsoil to finish it.

What is Class A roadstone and what is it used for in Pocahontas County?

Class A roadstone is the 3/4 inch crushed limestone base course with the fines left in, so it binds and compacts. In Pocahontas County it goes under driveways, parking pads, shed bases and farm lanes.

How deep should a gravel driveway base be in Pocahontas County?

Depth depends on what the drive carries and what the ground under it does. This is pothole country, so ground that holds water needs more drainage beneath it. Size the quantity on the product calculator once you know your area, and put clean rock under any stretch that stays wet.

Materials Delivered in Pocahontas County

Pocahontas County sits on the Des Moines Lobe, the youngest glacial ground in Iowa. That means thick, compact pebbly loam till under most of the county, with sand and gravel strung along old meltwater channels.

Pick your material by what the job needs. Base material goes down first, washed stone moves water, and sand, soil and decorative rock finish the work.

Class A roadstone is the one to know on a base job.

11. County engineers and city entrance standards write the same material as Class A roadstone.

Use 1 inch roadstone when a drive is new or a lane is taking heavy equipment. Grade it in first, then cap it with the finer roadstone.

Reach for clean rock when water has to leave. It is washed and open graded, so it will not hold moisture the way a fines-bearing base does.

Set limestone screenings under pavers and flagstone, or sweep them into the joints.

For decorative work, river rock and large river rock round out beds, borders and dry creek beds. Natural Pea Gravel suits walkways, play areas and small drainage runs, and garden soil or shredded mulch finishes the planting areas.

Choosing the Right Material

Webster County shares this ground. It sits on the Des Moines Lobe too, the same thick pebbly loam till of the Dows Formation, 45 to 60 feet deep, with sand and gravel along old meltwater channels and stony ground on the moraine ridges.

Buena Vista County and Sac County reach into more than one ground region, taking in the Des Moines Lobe and the Northwest Iowa Plains. Where the till thins and the ground turns sandier, water moves through faster and a base course holds its shape differently.

On ground like that, lean on washed stone for drainage and on roadstone where you want a surface that binds. The choice follows the ground.

Ground Conditions Across Pocahontas County

This is pothole country. The drainage network across the Des Moines Lobe 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. Plan a drainage layer of clean rock under anything that has to stay dry, and keep the fines-bearing base out of the wet spots.

Bank cutting shows up along the larger rivers in this part of Iowa, and ditch and tile outlet scour is common. Riprap armors those edges, and it also protects slopes where runoff concentrates on the moraine ridges.

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.

Winters here are long and cold with a deep frozen season, and repeated freeze-thaw heaves gravel drives, lanes and field entrances as the ground lets go in spring. Frost depth is commonly 42 inches in this region, and the local building official sets footing depth.
