Materials for Andover Projects

Base and driveway surfacing is where most ground work here starts, and base course is the material that carries it.

It builds 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. On a gravel drive it works as the crushed top course.

Around Sioux Falls and Dell Rapids, 3/4 quartzite brings the hardest rock sold in the southeast corner, and it suits drives, drainage beds and landscape stone.

Washed stone handles water. Washed rock, which is what the Dakotas call clean drainage stone, goes into drain tile, drywells, sump and downspout runs, and window wells.

Sizes are often quoted in inches here, so a yard will know #57 stone as 1 inch washed rock for drainage and drain tile beds.

Sand and soil finish the job. Mason sand sets brick and block, fills paver joints and doubles as play sand.

Topsoil, also called black dirt, rebuilds a growing layer over stony till. Fill dirt raises grade and backfills before a base course goes down.

Decorative stone holds up to wind where bark mulch does not. River rock beds borders and rock mulch around foundations; large river rock builds dry creek beds and heavier erosion work.

Ground and Conditions in Andover

This part of the state sits on deep glacial till, hundreds of feet of it in places, with stony loam over dense till and sand and gravel outwash along old meltwater channels. The till takes water slowly.

Yards and drive edges stay wet long after the surface looks dry.

Across the Coteau des Prairies, closed pothole basins have no outlet, so snowmelt and spring rain sit where they land. That standing water is why drainage rock and a stable base layer matter more than surface appearance.

Snowmelt and thunderstorm runoff cut ditches and drive edges on the coteau slopes, and wind scours bare open ground. Winters here are some of the coldest in the state, with deep frost, repeated freeze-thaw and drifting.

Gravel drives heave through the winter and soften when the frost comes out.

Frost depth is commonly 42 to 48 inches on the Coteau des Prairies, with the deeper figure used in the northern counties. There is no statewide figure, and the local building official sets it.

Frozen ground stops compaction, so the frost boil weeks in early spring are the worst time to place material.
