Bulk Gravel and Stone Delivery in Lake County, SD

Looking for gravel, stone and aggregate delivery in Lake County, SD? South Dakota Rock Supply brings bulk loads to your site, and base course is the place to start.

Base course is the crushed base layer under drives, pads and shop slabs.

Ground Conditions Across Lake County

Across the Coteau des Prairies, the ground is deep glacial till on a high plateau. Stony loam sits over dense till, with sand and gravel outwash along old meltwater channels.

That dense till takes water slowly. Closed pothole basins hold snowmelt and spring rain, so drive edges and yards stay wet long after the surface looks dry.

Plan around the working season. Base, driveway and paver work runs from the spring thaw into late fall, and frozen ground stops compaction.

The frost boil weeks in early spring are the worst time to place material. Gravel drives heave through winter and soften badly when the frost comes out.

Runoff from snowmelt and thunderstorms cuts ditches and drive edges on the coteau slopes. Wave action works on the glacial lakes, and wind scours bare open ground.

Materials Delivered in Lake County

Base course is a compacted base for driveways, parking pads and shed slabs.

Section 882 Table 1 keeps subbase, gravel cushion, aggregate base course, gravel surfacing and pit run apart as separate materials. County and city specifications point back at the same sections.

Gravel cushion is the cushion course rolled out under concrete and asphalt, and the crushed top course on a gravel drive.

3/4 quartzite is the pink Sioux Quartzite from the southeast corner, and it is the hardest rock sold there. It works for drives, drainage beds and landscape stone.

3/8 inch crushed stone tops a compacted base and beds pipe. Washed rock handles drain tile, drywells, sump and downspout runs, and window wells.

Riprap protects culvert outlets, dam faces, stock dam spillways and reservoir shoreline.

Topsoil and garden soil build a growing layer over stony till. Fill dirt raises grade and backfills before a base course goes down.

Choosing the Right Material

Minnehaha County and McCook County sit on the southeastern till plains and Big Sioux valley. That ground is loess-mantled and dissected glacial till with deep silty prairie soils, and Sioux Quartzite bedrock sits close to the surface.

Lake County ground is different. Here it is deep glacial till on a high plateau, with stony loam over dense till and pothole basins that hold water.

Sand and gravel outwash along old meltwater channels is a local feature on the coteau. That outwash drains faster than the dense till around it.

Miner County shares the Coteau des Prairies ground region, so the soil and drainage picture there is the same as here. No difference to plan around.

Where the ground is dense till, a drainage layer matters more than it does on sandy outwash. Washed rock and 3/8 inch crushed stone handle that work.

On a drive, base course and gravel cushion build the load-bearing layer. Driveway gravel resurfaces an existing farm or acreage drive, and walkway gravel gives paths a finer surface.
