Materials for Delmont Projects

Grading and bed prep carry a lot of the work in this part of the state. The ground is flat glacial till and old lake-bed silt, with very little gravel at the surface.

That means the growing layer and the build-up layer both have to come in by truck.

Top Soil, also called black dirt, goes down for lawns and bed prep over that stony till. A real growing layer has to be brought in rather than worked up out of what is already there.

Garden Soil suits raised beds, shelterbelt planting pockets and vegetable ground. Fill Dirt is clean fill for raising grade and backfilling before a base goes down.

Base and Stone

Base Course is the crushed base layer, and in South Dakota contractors order it by that name. It goes under driveways, parking pads and shop or shed slabs.

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

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

Washed Stone and Sand

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

Washed Sand beds and levels under slabs and pavers. Mason Sand is for brick and block work, paver joint sand and play sand.

Decorative and Mulch

3/8" Natural Pea Gravel gives a rounded, walkable surface for paths, play areas and dog runs. River Rock works for decorative beds and rock mulch around foundations, where wind makes bark mulch a losing battle.

Shredded Mulch holds moisture through a dry, windy summer in beds, tree rings and shelterbelt plantings.

Ground and Conditions in Delmont

Across the James River Lowland and Lake Dakota Plain, there is almost no fall across the ground. Snowmelt and heavy rain sit on the surface because the tight lake-bed silts below the topsoil drain very slowly.

That shapes what you build with. Water needs somewhere to go, so drainage stone and a graded surface matter as much as the base itself.

Runoff after heavy rain also cuts. Field runoff crossing a drive gullies it, and ditch cutting follows.

Bare flat ground blows in spring.

Winters here bring deep frost and repeated freeze-thaw. Frost depth is commonly 42 to 48 inches in this part of the state, and the local building official sets the figure that applies to your job.

Plan deliveries around the thaw. Once the ground dries, the season runs through to freeze-up.

What stone should I use for drainage in Delmont?
