Mason Sand for Patios in Dallas, SD

Order gravel and aggregate delivery in Dallas, SD online, by the ton or by the yard, and South Dakota Rock Supply tips it on your site. Start with base course for the pad, then bed the pavers.

This is gumbo country. Weathered Pierre shale sits under thin clay soils across the Pierre shale plains and Missouri breaks, and it swells when it takes on water.

Ground and Conditions in Dallas

Gumbo sheds water rather than taking it in. Rain runs straight off, and what does soak in makes the clay swell and stay soft for days.

A thin base course fails here in a way you can see from the road. The pad pumps, the edge drops, and the surface cracks along the joints.

The fix is a base course that carries the load and a drainage layer that moves water out from under it. How wet the gumbo is matters more than the calendar.

The ground is unworkable while it is wet, and the season runs from the spring dry-out to freeze-up. Cold, open, windy winters bring deep frost and hard freeze-thaw cycling.

Drives heave in winter and turn to gumbo when the frost comes out. Frost depth is commonly 42 inches, the figure Rapid City uses in its adopted residential code, and the local building official sets it.

Materials for Dallas Projects

Bedding is where a paver or flatwork job is won. Set the pavers on stone screenings and the joints hold their line through a freeze-thaw winter.

Stone screenings, also called crusher dust or chips and dust, pack hard under pavers and flagstone and fill the joints between them. Order Stone Screenings for bedding and joint filling.

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

Order Washed Sand for that work.

Mason sand goes into brick and block work, paver joint sand and play sand. Order Mason Sand where mortar or a fine joint is wanted.

Under all of it sits base course. It also goes by aggregate base course, 3/4 minus and crushed base.

Order Base Course for driveways, parking pads and shop and shed slabs.

Gravel cushion, also called crusher run, is the cushion course rolled out under concrete and asphalt and the crushed top course on gravel drives.

Order Gravel Cushion for that layer.

For drainage beside a pad, washed rock, also called drain rock or clean rock, handles drain tile, drywells, sump and downspout runs and window wells. Order Washed Rock for those runs.
