Order Base Course and Crushed Stone in Clay County, SD
South Dakota Rock Supply runs gravel, stone and aggregate delivery in Clay County, SD. Start with base course when a drive, pad or slab needs a crushed layer under it.
In this part of the Southeastern till plains and Big Sioux valley, silty loess soils crust and shed water, so drainage decides what a site needs.

Ground Conditions Across Clay County
The working season here is the longest in the state, running from the spring thaw into late fall. Wet spells break it.
Silt soils turn soft and will not compact when they are wet.
Frost goes deep and freeze-thaw heaves drives, walks and slabs every spring. The residential code adopted in Sioux Falls sets frost depth at 42 inches, and the local building official sets the figure in other towns.
Across the Southeastern till plains and Big Sioux valley, loess-mantled glacial till leaves deep silty prairie soils, with sand and gravel along the river valleys and quartzite bedrock close to the surface in places. Water has nowhere to go over shallow rock.
Materials Delivered in Clay County
Base course is the crushed base layer, also called aggregate base course, 3/4 minus or crushed base.
That is the name contractors order by here.
Use Base Course under driveways, parking pads, and shop or shed slabs. Gravel cushion is the cushion course rolled out under concrete and asphalt, and the crushed top course on a gravel drive.
Sand and soil round out a site. Mason Sand goes into brick and block work, paver joint sand and play sand.
Washed Sand beds and levels under slabs and pavers. Fill Dirt raises grade and builds a pad up before base course goes down.
Choosing the Right Material
Pick by size and by what the layer has to do. Coarse angular rock moves water and carries load.
Fine material beds and packs. Clean stone drains; material with fines compacts.
- #4 Crushed Stone, about 1 1/2 inch clean rock, for heavy drainage, approaches and trench bottoms in wet ground.
- #57 Stone, about 1 inch washed rock, for drainage, drain tile beds and concrete aggregate.
- #8 Crushed Stone for fine drainage, paver joints and concrete aggregate.
- #89 Crushed Stone for tight bedding and joint filling.
- Railroad Ballast for track beds and severe drainage where a large angular rock is needed.
