3/4 Quartzite, Stone and Soil Delivery in Oacoma, SD

South Dakota Rock Supply brings gravel and aggregate delivery in Oacoma, SD, and the ground here shapes what you order. Weathered Pierre shale sits under thin clay soils, and everyone in this part of the state calls that sticky, swelling clay gumbo.

Gumbo sheds water instead of taking it in, so a drive pad starts with base course. Order it by the ton or the yard and the truck tips it on site.

Materials for Oacoma Projects

Water is the reason this page leads on washed stone. Gumbo will not absorb a hard rain, so roof runoff and driveway runoff have to go somewhere, and clean open stone gives it a place to go.

Washed Rock, also called drain rock or clean rock, is the usual Dakotas word for clean drainage stone. It suits drain tile, drywells, sump and downspout runs, and window wells.

#57 Stone is a one inch washed rock for drainage, drain tile beds and concrete aggregate. South Dakota yards sell it by the inch, so ask for it that way.

#4 Crushed Stone is the one and a half inch clean rock for heavy drainage and trench bottoms in wet ground. #67 Stone handles drainage and concrete work a size down.

For the drive itself, Base Course is the compacted layer under a driveway, parking pad or shed slab. Gravel Cushion is the cushion course rolled out under concrete and asphalt, and it also tops a gravel drive.

Finer material finishes the job. 3/8" Crushed Stone tops a compacted base and beds pipe, and Stone Screenings pack hard under pavers and flagstone.

Ground and Conditions in Oacoma

Timing here follows the ground more than the calendar. While the gumbo is wet it is unworkable, so the season runs from the spring dry-out to freeze-up, and that is when a delivery makes sense.

Across the Pierre shale plains and Missouri breaks, rain runs straight off the clay instead of soaking in. What does soak in makes the clay swell and stay soft for days, which is why a drainage layer matters as much as the base.

The breaks also cut and scour after thunderstorms, and reservoir shorelines take wave action. On a steep site, that is where riprap or larger stone earns its place.

Winters are cold, open and windy, with deep frost and hard freeze-thaw cycling. Drives heave and then turn to gumbo when the frost comes out, so a base course layer has to carry the traffic above it.
