New Holland sits in Douglas County on flat glacial till and old lake-bed silt. That ground shapes what goes under a patio before anything else does.

Ground and Conditions in New Holland

Across the James River Lowland and Lake Dakota Plain, the ground is flat to gently rolling glacial till over silt and clay. Deep dark prairie soils sit on top, and there is little gravel at the surface.

Almost no fall means snowmelt and heavy rain sit where they land. The tight lake-bed silts below the topsoil drain very slowly, so water lingers.

That is the failure a thin base shows here. Water sits in the bedding, the pavers rock, and joints open.

A deep, well-graded base is the fix, and it has to shed water rather than hold it.

Work waits for the ground to dry in spring. These flat black soils stay soft far longer than the coteau, and the season then runs to freeze-up.

Cold winters bring deep frost and repeated freeze-thaw. The flat ground and heavy soils make the spring thaw slow and muddy.

Frost depth in the region is commonly 42 to 48 inches, with Aberdeen using 48 inches, and the local building official sets the figure.

Materials for New Holland Projects

Bedding under pavers and flatwork is where a patio is won or lost.

Base Course goes down first under drives, parking pads and shop slabs. It is also called aggregate base course, 3/4 minus or crushed base.

Gravel Cushion is the cushion course rolled out under concrete and asphalt. In South Dakota it is rolled to a stable surface rather than to a set density.

Stone Screenings bed pavers and flagstone and fill the joints. Screenings also pack hard as a top for walks, and are sold as crusher dust or chips and dust.

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

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