Ground and Conditions in Alexandria

Across the James River Lowland and Lake Dakota Plain, the land lies flat and the silt and clay below the topsoil drain slowly. Snowmelt and heavy rain sit where they fall.

On a patio or walk, that shows up first in the bedding layer. Water trapped under pavers or a slab finds the soft spots and works the bedding loose, and the surface starts to rock and dip.

Field runoff crossing a drive cuts gullies, and bare flat ground moves in spring wind. Sheet flow after a heavy rain does the same work along ditch lines.

Cold winters bring deep frost and repeated freeze-thaw. The flat ground and heavy soils make the spring thaw slow and muddy, so work waits for the ground to dry.

Frost depth is commonly 42 to 48 inches across this part of the state. Aberdeen uses 48 inches, and the local building official sets the figure for a given job.

Materials for Alexandria Projects

Bedding under pavers and flatwork is where a patio job is won or lost here. The bedding has to stay put when the ground below it holds water.

Start with Base Course. It also goes by aggregate base course, 3/4 minus or crushed base.

It builds drives, parking pads and shop or shed slabs.

Gravel Cushion is the South Dakota term for the cushion course rolled out under concrete and asphalt.

It also acts as the crushed top course on a gravel drive.

For the bedding layer itself, Stone Screenings pack hard under pavers and flagstone and fill the joints. Washed Sand beds and levels under slabs and pavers, and mixes into tight clay ground.

Top a compacted base with 3/8" Crushed Stone, also called 3/8 minus or chip rock. It also handles fine drainage and pipe bedding.

Mason Sand handles brick and block work, paver joint sand and play sand. 3/4 Quartzite covers drives, drainage beds and landscape stone.

For drainage, Washed Rock fills drain tile, drywells, sump and downspout runs, and window wells. It is the usual Dakotas word for clean drainage stone.

In the beds, River Rock works as decorative cover and rock mulch around foundations, where wind makes bark mulch a losing battle. Top Soil and Garden Soil rebuild a growing layer over stony till.
