3/8 Inch Crushed Stone and Bulk Aggregates for Mission Hill, SD

South Dakota Rock Supply handles gravel and aggregate delivery in Mission Hill, SD, by the ton and by the yard. This corner of Yankton County sits on deep silty prairie soils over glacial till, and that ground decides how much base course a drive or pad really needs.

Silty ground crusts on top and sheds water, so water moves sideways instead of soaking in. Base course is the crushed base layer South Dakota contractors order by name, and it is the layer that carries a drive once the subgrade is right.

Materials for Mission Hill Projects

Washed stone is the place to start on a drainage job. Washed rock, also called drain rock or clean rock, has no fines left in it, so water passes through instead of sitting in the pile.

That makes it the material for drain tile, drywells, sump and downspout runs, and window wells. A downspout that dumps against a foundation on silty ground sends water right back into the soil, and a clean stone run carries it away instead.

On the coarser end, 1 1/2 inch clean rock handles heavy drainage, approaches and trench bottoms in wet ground. #57 stone, a 1 inch washed rock, works for drainage and drain tile beds, while #67 stone is a size down for the same kind of work.

Riprap is the answer where water arrives with force. Class B riprap and field stone riprap go at culvert outlets, dam faces, spillways and stream banks.

For the surface, base course is the compacted layer under drives, parking pads and shop or shed slabs. Gravel cushion is the South Dakota term for the cushion course rolled out under concrete and asphalt, and it also acts as the crushed top course on a gravel drive.

A finer top layer changes how a drive or walk feels underfoot. 3/4 quartzite, the pink Sioux Quartzite from the southeast, is a hard angular rock for drives, drainage beds and landscape stone.

3/8" Crushed Stone tops a compacted base and beds pipe.

Stone screenings pack hard for paver and flagstone bedding, joint filling and walk surfaces. Walkway Gravel gives paths a finer, walkable finish, and 3/8" Natural Pea Gravel suits paths, play areas and dog runs with a rounded stone.

Delivery to Mission Hill and the Surrounding Area

You order online and pick a delivery date at checkout. Quantities are ordered by the ton or by the yard, and each product page has a calculator if you want to size the load before you order.

A dump truck tips the load in one pile at the site. Material is delivered across Mission Hill and the rest of Yankton County, including Yankton, Gayville, Volin, Lesterville and Utica.

One delivery covers a single drop, so think about where the pile should land before the truck arrives. Nothing on site gets moved or spread after the tip.

Ground and Conditions in Mission Hill

The working season here is the longest in the state, running from the spring thaw into late fall. Wet spells break it, because silt soils turn too soft to compact and a load dropped on them can sink.

Timing a delivery around that matters as much as the material itself. Across the Southeastern till plains and Big Sioux valley, loess-mantled till and silty prairie soils sit over sand and gravel along the river valleys.

Water is the other half of the picture. Silty loess soils crust and shed water, and shallow bedrock leaves it nowhere to go in places, so drainage stone and a clean stone run do real work on a Mission Hill lot.

Spring also brings gullying on dissected slopes and sheet erosion on bare silt. Frost goes deep and freeze-thaw heaves drives, walks and slabs every spring, which is why the base layer under them has to be built to suit the ground.
