Bulk Gravel and Stone Delivery in Spink County, SD
South Dakota Rock Supply handles gravel, stone and aggregate delivery in Spink County, SD. Base course is the crushed base layer contractors here order by name, and it is the starting point for drives, parking pads and shop slabs.
This is flat glacial till and old lake-bed ground, so a drive or pad sits on soft, tight soil. The right material and the right drainage matter more here than on higher ground.

Materials delivered in Spink County
Section 882 Table 1 keeps it apart from gravel cushion, gravel surfacing and pit run, so the terms are not interchangeable.
Use base course under driveways, parking pads and shop or shed slabs.
Gravel cushion is the South Dakota term for the cushion course rolled out under concrete and asphalt.
3/8 inch crushed stone tops a compacted base and beds pipe. Washed rock is the clean stone for drain tile, drywells and downspout runs.
Natural Pea Gravel suits paths and play areas where a rounded, walkable stone is wanted.
Ground conditions across Spink County
Across the James River Lowland and Lake Dakota Plain, the ground is flat to gently rolling glacial till over the silt and clay floor of glacial Lake Dakota. The prairie soils are deep and dark, with very little natural relief and little gravel at the surface.
There is almost no fall across the lowland, so snowmelt and heavy rain sit on the surface. The tight lake-bed silts below the topsoil drain very slowly, which is why a drainage layer matters on a drive or pad.
Sheet flow and ditch cutting follow heavy rain, and field runoff crossing a drive cuts gullies. Bare flat ground also blows in spring.
Work waits for the ground to dry, and the flat black soils stay soft far longer than the coteau does.
Winters are cold with deep frost and repeated freeze-thaw, and the flat ground makes the spring thaw slow and muddy. Frost depth is commonly 42 to 48 inches in this part of the state, and the local building official sets the figure.
Choosing the right material
Day County and Clark County both sit on the Coteau des Prairies, which is deep glacial till on a high plateau with stony loam and sand and gravel outwash along old meltwater channels. That ground is not the same as the flat lake-bed silts here.
On that stony loam, a base course sits on firmer, better-draining ground than it does on the tight silts of the James River Lowland. Hand County lies on the Missouri Coteau, a hummocky jumble of knobs and closed kettles in stony till over Pierre shale.
That ground has gravel in the kames and no natural drainage network across much of it, so water stands in the low spots. Here the flat ground and slow-draining silts are the reason a drainage layer earns its place.
