What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone is angular, with broken faces that lock together when it is compacted, so it works as a base or a drainage layer. Natural Pea Gravel is rounded and smooth, which makes it walkable but poor at holding a slope or carrying a load. In Charles Mix County, crushed base course and quartzite go under drives, while Natural Pea Gravel suits paths, play areas and dog runs.

Should I order material by the ton or by the yard?

Either one works, and the choice is yours at checkout. Order by the ton when you are matching a spec or quoting a job, and by the yard when you are thinking about the volume of a hole or a bed. Each product page has a calculator you can use before you order.

Which stone is best for drainage in Charles Mix County?

Washed Rock is the clean drainage stone for drain tile, drywells and window wells, and 3/4 Quartzite handles drainage beds. Where a closed basin sits over gumbo and water has nowhere to run, clean open stone lets it move instead of ponding. Riprap covers the spillways and shorelines.

Crushed Stone and Sand, Charles Mix County, SD

Water has nowhere to run across much of the Missouri Coteau. The kettles and sloughs are closed basins, and low ground stays saturated.

That is why gravel, stone and aggregate delivery in Charles Mix County, SD starts with base course and clean drainage stone.

Plan around the working season. The window runs from the spring thaw to freeze-up, and wind and drifting stay a factor well into spring and again from late fall.

Base Course is the crushed base layer, also called aggregate base course or 3/4 minus.

Contractors order base course by that name for driveways, parking pads, and shop and shed slabs.

Gravel Cushion is the South Dakota term for the cushion course rolled out under concrete and asphalt. It also acts as the crushed top course on a gravel drive.

Crushed stone runs by size. 3/4 Quartzite is the pink Sioux Quartzite from the southeast, the hardest rock sold in that corner of the state, and it goes into drives, drainage beds and landscape stone.

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

Stone Screenings, or chips and dust, bed pavers and flagstone, fill joints, and pack down hard on walks. Riprap handles culvert outlets, dam faces, stock dam spillways and stream banks.

For growing ground, Top Soil builds a real layer over stony till and gumbo. Fill Dirt raises grade and backfills a pad before base course goes down.

Garden Soil fills raised beds and shelterbelt planting pockets. Washed Sand beds and levels under slabs and pavers.

Ground conditions across Charles Mix County

Start with the working season when you time a delivery. The window between the spring thaw and freeze-up is short, and wind and drifting stay a factor well into spring and again from late fall.

Order while the ground is workable.

The Missouri Coteau ground is hummocky stagnation moraine. That means a jumble of knobs and closed kettles in stony glacial till lying over Pierre shale, with gravel in the kames and no natural drainage network across much of it.

Low ground stays saturated.

Weathered Pierre shale, called gumbo, sits under the till and stops what does soak through. On a wet, closed basin, drainage stone matters more than another inch of base.

Erosion comes from three directions on the coteau: wind scour on the open knobs, runoff cutting the steeper slopes and the Missouri breaks, and wave action on reservoir shorelines. Riprap and large river rock protect those edges.

Long, cold, windy winters bring deep frost, heavy drifting and hard freeze-thaw cycling on exposed ground. Frost depth runs about 42 to 48 inches in the northern counties, and there is no statewide figure; the local building official sets it here.

Choosing the right material

Hutchinson County and Bon Homme County share the same ground region as each other: loess-mantled and dissected glacial till with deep silty prairie soils, sand and gravel along the big river valleys, and Sioux Quartzite bedrock close to the surface. Charles Mix County ground is hummocky stagnation moraine over Pierre shale.

That difference shows up in drainage. Where till is closed and shale sits below, plan on clean stone for the wet spots and riprap on the cut banks.

Deep silty prairie soils take a compacted base differently than stony till does.

Douglas County is flat to gently rolling glacial till and the silt and clay floor of glacial Lake Dakota, with deep dark prairie soils and very little gravel at the surface.

Granular material there has to be hauled in, which is why base course is named by spec rather than by what the ground already provides.

Size picks itself once you know the job. Coarse angular rock drains and holds a slope.

Crushed base with fines compacts into a surface. Rounded Natural Pea Gravel stays walkable.

Screenings pack hard under pavers.
