Large River Rock and Bulk Aggregates for Interior, SD

What holds a bank or a swale together out here? Coarse stone, sized right and placed where the water runs.

South Dakota Rock Supply brings gravel and aggregate delivery in Interior, SD, from base course for drives to the heavy rock that armors a slope. Order online by the ton and a truck tips it at your site.

Out on the White River Badlands, southern tablelands and sandhills side, flashy runoff off bare shale makes bank protection a real job. That is where sizes like riprap and large river rock earn their place.

Materials for Interior Projects

Start coarse. Slope, swale and bank protection calls for rock big enough to stay put when water hits it hard.

• Riprap, sized by class from A to F on median rock weight, for culvert outlets, dam faces, spillways and shoreline. Ledge rock and field stone are both allowed.
• Large River Rock for dry creek beds, draw bottoms and heavier decorative and erosion work.
• River Rock for decorative beds, borders and rock mulch around foundations, where wind makes bark mulch a losing battle.

Move down a step and the work changes. 3/4 Quartzite covers drives, drainage beds and landscape stone, and the pink to red Sioux Quartzite is the hardest rock sold in the southeast corner.

For a drainage layer rather than a bank, Washed Rock goes into drain tile, drywells, sump and downspout runs, and window wells. It drains clean, which is the whole point.

Then the fine end. Stone Screenings bed and joint pavers and flagstone and pack a hard top on walks.

Top Soil builds the growing layer over stony ground.

Ground and Conditions in Interior

The working season here runs long and dry from the spring thaw to freeze-up, broken by short violent thunderstorms. Those storms can put draws and low crossings out of reach for a day or two.

Plan your delivery around that window rather than against it. Ground that has just taken a hard rain will not carry a loaded truck well, and a grade that is about to get a base course wants dry weather behind it.

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

Water behaves differently on those two ground types. Sand drains almost too fast to hold a base together, while bare shale sheds a flashy runoff into the draws and gullies.

That is why bank protection takes coarse stone and why a drive on sand wants its base thought through before anything goes on top.
