Ground and Conditions in Dell Rapids

Across the Southeastern till plains and Big Sioux valley, the ground is loess-mantled glacial till over deep silty prairie soils. Sioux Quartzite bedrock sits close to the surface in this corner of the state.

That mix decides how a patio or walk behaves.

A thin base is the failure mode you see first. Silt crusts and sheds water, so a shallow layer of bedding sand washes out from under the pavers and the surface rocks and drops at the edges.

Shallow quartzite leaves water nowhere to go in places. Where the rock is near the surface, drainage has to be built into the section instead of counting on the soil to take it.

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

Footing depth is a building question, not a base question.

Gullying on the dissected slopes and sheet erosion on bare silt in spring are the erosion drivers in this part of the state. A patio cut into a slope needs its edges held, and bare ground around new work needs cover before the spring rains.

Materials for Dell Rapids Projects

Bedding under pavers and flatwork is the work that decides whether a patio stays flat. The bedding layer has to sit on something that will not move, and the joints have to be filled with a material that packs hard.

Base Course, also called aggregate base course or 3/4 minus, is the compacted layer under drives, parking pads and shop slabs.

Gravel Cushion, also called crusher run, is the cushion course rolled out under concrete and asphalt.

Stone Screenings, also called crusher dust or chips and dust, bed pavers and flagstone and fill the joints. Screenings pack hard and give a walk a firm top.

Washed Sand, also called concrete sand, beds and levels under slabs and pavers. It also mixes into tight clay ground.

3/4 Quartzite, also called Sioux quartzite or pink quartzite, is the hardest rock sold in the southeast corner. It suits drives, drainage beds and landscape stone.

Mason Sand handles brick and block work, paver joint sand and play sand.
