Crushed Stone, Sand and Gravel in Sioux Falls, SD

South Dakota Rock Supply handles gravel and aggregate delivery in Sioux Falls, SD for two kinds of buyers: contractors building drives and pads, and homeowners fixing the one they already have. Base course is the material both groups start with.

This corner of the state sits on loess-mantled glacial till, with Sioux Quartzite close to the surface. What you put down has to suit that ground.

Materials for Sioux Falls Projects

Base and driveway surfacing is where most Sioux Falls projects begin, so start with base course.

Base Course is a compacted base for driveways, parking pads, and shop or shed slabs. It carries the load so the surface above it can hold.

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

Driveway Gravel resurfaces an existing farm or acreage drive. It also tops a compacted base course where the drive needs a fresh wearing surface.

For the rock itself, Sioux Quartzite is quarried around Sioux Falls and Dell Rapids. The pink to red stone is the hardest rock sold in the southeast corner.

3/4 Quartzite suits drives, drainage beds and landscape stone. 3/8" Crushed Stone tops a compacted base, beds pipe and handles fine drainage.

Where water has to move, Washed Rock covers drain tile, drywells, sump and downspout runs, and window wells. Washed rock is the usual Dakotas word for clean drainage stone.

Stone Screenings bed pavers and flagstone and fill the joints between them. They also pack hard as a top for walks.

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

Washed Sand beds and levels under slabs and pavers.

Top Soil builds a growing layer for lawns and bed prep. Garden Soil fills raised beds and vegetable ground.

Ground and Conditions in Sioux Falls

Water is the driver here. Rain and snowmelt arrive on silty loess soils that crust and shed water rather than soak it in, and shallow quartzite bedrock leaves that water nowhere to go in places.

Across the Southeastern till plains and Big Sioux valley, that combination shows up as gullying on dissected slopes and sheet erosion on bare silt in spring. Both move soil off a site fast.

A clean drainage stone like washed rock gives the water a path. A fines-bearing material holds it instead, which is the wrong job for the wrong stone.

Frost still goes deep in the mildest part of South Dakota, and freeze-thaw heaves drives, walks and slabs every spring. The residential code adopted in Sioux Falls sets frost depth at 42 inches, with the local building official setting the figure in other towns.

The working season runs from the spring thaw into late fall, the longest in the state. Wet spells break it, because silt soils are too soft to compact when saturated.
