Large River Rock and Bulk Aggregates for Pine Ridge, SD

South Dakota Rock Supply handles gravel and aggregate delivery in Pine Ridge, SD, by the ton. Start with base course if you are building a drive or a pad, and size the load on the calculator before you order.

Ground here runs to eroded shale, silt and sand, so what protects a slope is not the same as what makes a road.

Materials for Pine Ridge Projects

Coarse, angular stone is what holds ground in place where runoff gets moving. Start at the heavy end and work down to the fines.

Riprap is the first choice for culvert outlets, stock dam spillways, stream banks and reservoir shoreline.

Railroad Ballast is a large angular rock for track beds, heavy equipment hard standing and severe drainage.

Large River Rock fills dry creek beds and draw bottoms, and does heavier decorative and erosion work. River Rock is the smaller cut for decorative beds and rock mulch around foundations, where wind makes bark mulch a losing battle.

#4 Crushed Stone, sold by size as 1 1/2 inch clean rock, handles heavy drainage, approaches and construction entrances, and trench bottoms in wet ground.

Below the coarse end, and it is the term contractors here order by. It goes under driveways, parking pads and shop or shed slabs.

Gravel Cushion is the cushion course under concrete and asphalt, and the crushed top course on a gravel drive.

Washed Rock is clean drainage stone for drain tile, drywells, sump and downspout runs and window wells. 3/8" Crushed Stone tops a compacted base and beds pipe.

Stone Screenings bed pavers and flagstone and fill the joints, and pack hard on a walk. 3/8" Natural Pea Gravel suits paths, play areas and dog runs.

Ground and Conditions in Pine Ridge

The working season runs long and dry from the spring thaw to freeze-up. It is broken by short, violent thunderstorms that make draws and low crossings impassable for a day or two, so timing a delivery matters.

Across the White River Badlands, southern tablelands and sandhills, the ground runs to eroded shale, silt and volcanic ash, with silty and sandy soils and wind-formed sand ridges along the Nebraska line.

Runoff off bare shale is flashy, and sand drains almost too fast to hold a base together. Very little water is held near the surface, which is why drainage stone and coarse cover do real work here.

Erosion in this part of the state is some of the fastest in the country, with gully cutting on the tablelands and wind moving loose sand on the southern ridges. Winters bring deep frost and wide swings between day and night, and exposed shale and silt weather fast under repeated freezing and thawing.

Questions About Stone in Pine Ridge

What stone should I use for drainage in Pine Ridge?

For slope, swale and bank work, riprap is sized by class from A to F on median rock weight.

What should I have ready when the truck arrives?

Have the pile spot clear and reachable. The truck tips the load in one pile, so the ground you want it on should be open before it backs in.
