Base Course, Sand and Gravel Delivery in Campbell County, SD

South Dakota Rock Supply handles gravel, stone and aggregate delivery in Campbell County, SD. If you are building a farm drive, a shop pad or a drainage run, the load usually starts with base course.

Base course is the crushed base layer South Dakota contractors order by name. Around Herreid, Pollock and Mound City the ground it goes on is stony glacial till over Pierre shale, so the water question comes first.

Ground Conditions Across Campbell County

This part of the Missouri Coteau is hummocky stagnation moraine. Picture a jumble of knobs and closed kettles in stony glacial till lying over Pierre shale, with gravel in the kames.

Water has nowhere to run. The kettles and sloughs are closed basins, and the shale under the till stops what does soak through, so low ground stays saturated.

That shapes what you build with. A pad on low ground wants fill dirt under it before any base course goes down, so the grade sits above the wet layer.

Wind scour works the open knobs, runoff cuts the steeper coteau slopes, and wave action works reservoir shorelines. Riprap and large river rock are the answers for those edges.

Winters here are long, cold and windy, with deep frost, heavy drifting and hard freeze-thaw cycling on exposed ground. The working season sits between the spring thaw and freeze-up, and wind and drifting stay a factor well into spring and again from late fall.

Frost depth is not a statewide number. The local building official sets footing depth, so check with yours before you plan anything structural.

Materials Delivered in Campbell County

County and city specifications point back at the same sections.

That is how the material is named and ordered here. Order base course for driveways, parking pads, and shop and shed slabs.

Washed stone covers drainage in a few sizes. #57 Stone is one inch washed rock for drain tile beds and concrete aggregate, and #67 Stone is the size down from it.

For tighter work, Stone Screenings bed pavers and flagstone and fill the joints. 3/8" Crushed Stone tops a compacted base and beds pipe.

On the soil side, Fill Dirt raises grade and backfills before a base goes down, and Garden Soil fills raised beds and shelterbelt planting pockets.

You order online and a dump truck tips the load on site. Quantities are ordered by the ton or by the yard, and each product page has a calculator to help you size the load.

Have the drop spot clear and reachable before the truck arrives. The driver tips the load in one pile and does not spread it, so pick a spot you can work from.

Choosing the Right Material

Walworth County and McPherson County sit in the same region and the same ground region as Campbell County. Both are Missouri Coteau, hummocky stagnation moraine over Pierre shale, with gravel in the kames and no natural drainage network across much of it.

So the ground is the same, and so is the reasoning that follows from it. Closed basins and shale under the till mean low ground stays saturated in all three counties.

That points the same way on any of them. Fill dirt under a pad on low ground, base course over it, and clean washed stone where water has to move.
