Start with base course. It is the crushed base layer South Dakota contractors order by name, and it carries a drive or a slab pad.

Materials for Hill City Projects

Base course, also called aggregate base course or 3/4 minus, is the crushed base layer under drives, parking pads and shop slabs.

Order it from the Base Course page.

Gravel cushion is the South Dakota term for the cushion course rolled out under concrete and asphalt. It also works as the crushed top course on a gravel drive.

See Gravel Cushion.

For resurfacing an existing farm or acreage drive, Driveway Gravel tops a compacted base. For garden paths and walks that need a finer surface, use Walkway Gravel.

Washed stone handles water. Washed Rock, also called drain rock or clean rock, goes into drain tile, drywells, sump and downspout runs, and window wells.

Sand and soil round out the list. Mason Sand serves brick and block work, paver joint sand and play sand.

Top Soil builds a growing layer for lawns and beds.

Ground and Conditions in Hill City

Across the Black Hills, steep ground sends runoff downhill fast after heavy rain and snowmelt. Shallow soil over rock has nowhere to store that water, so it moves.

Some limestone ground swallows streams and returns them downstream. That shapes where a drainage layer earns its place and where water will sit.

Soils here run thin and gravelly over granite, pegmatite and schist in the core, with limestone and sandstone around the rim. Red clay soils sit in the Red Valley that rings the hills.

That mix means a pad often needs fill dirt before any base course goes down. Build the grade first, then cap it.

Slope wash on cut banks and drive shoulders is the other driver, and runoff off burned slopes after a fire. Riprap at a culvert outlet or along a bank slows that water down.

The season runs shorter at elevation than on the plains below. Snow lingers on high and shaded ground, and spring sends heavy runoff through the canyons.

This is the wettest and snowiest part of the state, with a long freeze-thaw season and hard frost at elevation. Rapid City uses a frost depth of 42 inches in its adopted residential code, and ground at elevation can run deeper where the local official sets it.
