Gregory sits on West River ground, where gumbo clay sheds rain instead of soaking it in. That shapes what you put under a drive, a pad or a slab.

Materials for Gregory Projects

Start with the base layer. Base course, also called aggregate base course or 3/4 minus, is the crushed base for driveways, parking pads and shop slabs.

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

Topping a compacted base calls for a finer stone. 3/8" Crushed Stone, sold as 3/8 minus or chip rock, also beds pipe and handles fine drainage.

For the southeast corner of the state, 3/4 Quartzite is the pink Sioux Quartzite quarried around Sioux Falls and Dell Rapids. It is the hardest rock sold there, and it goes into drives, drainage beds and landscape stone.

Water needs a way out. Washed Rock, also called drain rock or clean rock, is the usual Dakotas word for clean drainage stone.

Use it in drain tile, drywells, sump and downspout runs, and window wells.

Sand and soil round out a site. Mason Sand handles brick and block work, paver joint sand and play sand.

Washed Sand, or concrete sand, beds and levels under slabs and pavers. Top Soil, called black dirt, builds a real growing layer over gumbo.

Garden Soil fills raised beds and vegetable ground.

Decorative work has its own stone. 3/8" Natural Pea Gravel suits paths, play areas and dog runs where a rounded, walkable stone is wanted.

River Rock mulches beds and borders around foundations, where wind makes bark mulch a losing battle.

Ground and Conditions in Gregory

Water drives everything here. Gumbo sheds rain rather than taking it in, so runoff runs straight off, and what does soak in makes the clay swell and stay soft for days.

That soft ground is why the base layer matters more than the surface stone. A drive built over wet, swelling clay moves unless the base is built to carry the load.

Across the Pierre shale plains and Missouri breaks, thunderstorms cut rill and gully into the shale breaks.

The spec allows ledge rock or field stone.

Timing follows the ground, not the calendar. The ground is unworkable while it is wet, and the season runs from the spring dry-out to freeze-up.

Winters are cold, open and windy, with deep frost and hard freeze-thaw cycling.

Drives heave in winter and turn to gumbo when the frost comes out. Plan the base and the drainage together before you order.
