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

South Dakota Rock Supply handles gravel, stone and aggregate delivery in Hyde County, SD. The working season between the spring thaw and freeze-up is short, so timing a load matters.

Start with base course, the crushed layer South Dakota contractors order by name.

Across the Missouri Coteau, water has nowhere to run. The kettles and sloughs are closed basins, and the shale under the till stops what does soak through.

It is also called aggregate base course, 3/4 minus or crushed base.

Use it under driveways, parking pads, and shop or shed slabs.

Gravel cushion is a South Dakota term for the cushion course rolled out under concrete and asphalt.

Order it as Gravel Cushion.

Stone screenings are a fines-bearing material for bedding and joint filling, not a drainage stone. They bed pavers and flagstone, fill joints, and pack hard as a top for walks.

Order Stone Screenings.

Washed rock is clean drainage stone for drain tile, drywells, sump and downspout runs, and window wells. It carries water instead of holding it.

Order Washed Rock.

It protects culvert outlets, dam faces, stock dam spillways, stream banks and reservoir shoreline.

Order Riprap.

Topsoil is also called black dirt or screened topsoil. Over stony till, a real growing layer has to be brought in for lawns and bed prep.

Order Top Soil.

Fill dirt, or clean fill, raises grade and backfills a pad before a base course goes down. It is not pit run.

Order Fill Dirt.

Washed sand, also called concrete sand, beds and levels under slabs and pavers and mixes into tight clay ground. Mason sand serves brick and block work, paver joint sand and play sand.

Order Washed Sand or Mason Sand.

Ground conditions across Hyde County

This part of the state is hummocky stagnation moraine: a jumble of knobs and closed kettles in stony glacial till lying over Pierre shale, with gravel in the kames. There is no natural drainage network across much of it.

Water has nowhere to run, and the shale under the till stops what does soak through.

A thin base shows its failure fast here. Saturation softens the subgrade under a drive or pad, and the surface rutting that follows is the subgrade moving, not the gravel wearing out.

A thicker base course spreads the load over ground that stays wet longer.

Wind scours the open knobs and runoff cuts the steeper coteau slopes. Wave action works on reservoir shorelines.

Riprap on a culvert outlet or a dam face holds where bare soil will not.

Winters run long and cold, with deep frost, heavy drifting and hard freeze-thaw cycling on exposed ground. Frost depth is commonly 42 to 48 inches, with the deeper figure used in the northern counties.

There is no statewide figure, and the local building official sets it.

Choosing the right material

Hand County and Potter County share Hyde County's ground: the same hummocky stagnation moraine, the same stony till over Pierre shale, the same closed kettles with no drainage network. Material choices there follow the same reasoning as here.

Hughes County spans more than one zone. It takes in Missouri Coteau ground and Pierre shale plains with Missouri breaks.

On breaks ground, slope and runoff drive the choice toward riprap and clean drainage stone rather than a fines-bearing base.

On Hyde County ground, the practical split is simple. Base course and gravel cushion build and top a drive or pad.

Washed rock and the numbered sizes drain. Screenings bed pavers and pack a walk.
