Mason Sand for Patios in Fairfax, SD

Planning a paver patio, a shop slab or a new driveway pad starts with the right bedding, and South Dakota Rock Supply brings gravel and aggregate delivery in Fairfax, SD straight to your site. Under it all sits base course, the crushed base layer South Dakota contractors order by name.

Get the bedding right and the flatwork above it stays flat.

Fairfax sits in Gregory County on gumbo ground, the sticky swelling clay that sheds rain instead of soaking it in.

Ground and Conditions in Fairfax

Across the Pierre shale plains and Missouri breaks, weathered shale sits under thin clay soils. Gumbo sheds water rather than taking it in, so rain runs straight off a bare pad.

What does soak in makes the clay swell and stay soft for days.

A thin base shows its weakness fast on that ground. Flatwork loses support, edges drop, and pavers rock at the corners after a wet spring.

The fix is a real granular base layer that spreads the load and keeps water moving.

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.

Plan your material order around that window.

Winters here are cold, open and windy, with deep frost and hard freeze-thaw cycling. Drives heave in winter and turn to gumbo when the frost comes out, which is why the granular layers under flatwork carry the load.

Materials for Fairfax Projects

Bedding is the layer that makes or breaks pavers, flagstone and slab work. Bedding sand and fine crushed stone let you set units true and lock the joints, and they stay workable in front of the gumbo below.

Start below it with Base Course.

Rolled out as a cushion course under concrete and asphalt, Gravel Cushion is the South Dakota term for the layer that is rolled to a stable surface. On a gravel drive, the same material is the crushed top course.

For the bedding itself, Mason Sand beds brick, block and pavers and fills joints. Washed Sand, also called concrete sand, levels under slabs and pavers and mixes into tight clay ground.

Stone Screenings pack hard under flagstone and pavers and fill joints, and they leave a firm surface on walks. Where water has to leave the site, Washed Rock handles drain tile, sump runs and window wells.
