Mason Sand for Patios in Vienna, SD

South Dakota Rock Supply handles gravel and aggregate delivery in Vienna, SD, from base course for drives and pads to the bedding sand that goes under pavers and flatwork. This is Coteau des Prairies ground, stony loam over dense glacial till, so what you build on top of it matters.

You order online by the ton or the yard, and a dump truck tips the load on your site.

Ground and Conditions in Vienna

Across the Coteau des Prairies, the topsoil sits on dense till that takes water slowly. Closed pothole basins hold snowmelt and spring rain with no outlet to drain them.

That is why a thin base fails here. Water sits under the surface long after the ground looks dry, and a paver patio or slab bed laid on too little material moves and dips at the edges.

The fix is a real base course layer under the flatwork, with a bedding layer on top that stays even.

Snowmelt and thunderstorm runoff also cut ditches and drive edges on the slopes, and wind scours bare open ground. Bare soil does not stay put through a Coteau spring.

Base, driveway and paver work runs from the spring thaw into late fall. Frozen ground stops compaction, and the frost boil weeks in early spring are the worst time to place material.

Winters here bring deep frost, repeated freeze-thaw and drifting. Gravel drives heave through the winter and soften badly when the frost comes out.

Materials for Vienna Projects

Bedding is where most flatwork problems start, so it is worth ordering the right material for the layer under the pavers.

Start with base course, also called aggregate base course or 3/4 minus. It is the crushed base layer under drives, parking pads and shop slabs.

Above that base, stone screenings bed pavers and flagstone and fill the joints. Screenings also pack into a hard top for walks.

Mason sand is the other bedding choice, for brick and block work, paver joint sand and play sand. Washed sand beds and levels under slabs and pavers and mixes into tight clay ground.

For the cushion course rolled out under concrete and asphalt, order gravel cushion, the crushed top course on a gravel drive.

Where a drive or pad needs a compacted base first, fill dirt raises grade and builds the pad up before any base course goes down.
