Order Crushed Base and Crushed Stone in Fremont County, WY

Spring runoff off the Wind River Range cuts banks and gullies, and soft alkaline clay holds water under a drive long after the surface dries. Wyoming Rock Supply delivers gravel, stone and aggregate in Fremont County, WY, and crushed base is where most ground work starts.

Order by the ton or the yard, pick a delivery date at checkout, and a dump truck tips the load on site.

Materials delivered in Fremont County

Crushed base, also called 3/4 minus, is the standard Wyoming base material.

Grading W is the common one-inch-top-size base, and Grading GR is the 3/4 inch gradation. City and county work is usually written against Section 02190 of the Wyoming Public Works Standard Specifications, which uses the same letters and states that base shall be crushed base unless otherwise specified.

Use Crushed Base for driveways, shop and shed pads, parking areas and county-style lanes. Pit run is a separate pay item from crusher run in both spec books, and it is unprocessed pit gravel, not crushed material.

Order Pit Run for deep fill, raising grade and sub-base under a crushed base course, never as the finished driving surface.

Sand and soil round out a job. Washed Sand levels and beds flatwork and pavers, and acts as concrete sand.

Mason Sand goes into brick and block work, paver joints and play sand. Top Soil is screened for lawns and bed prep, and Garden Soil fills raised beds where native clay, gumbo or basin sand will not do on its own.

Ground conditions across Fremont County

Work runs from spring breakup into autumn on the basin floor, with a noticeably shorter window at Dubois and up toward the range. Time a delivery to the window you are actually building in, because ground that is still thawing will not take a load the way dry ground will.

Across the Wind River Basin and the Wind River front, the ground is an arid mix of shale-derived clay, badlands and river terrace gravel, with alkaline flats out in the basin and coarse granite outwash and cobble washed off the range.

Alkaline clay subgrade stays soft under a drive long after the surface has dried, so a base course needs enough depth to bridge that soft layer rather than sit on it.

Water arrives as snowmelt through late spring and as irrigation across the valley floor. Where drainage is the problem, washed rock and Crushed Stone move water instead of holding it, while fines-bearing material does the opposite.

Wind moves across the open basin, and gullies cut in badlands and along bluffs. Riprap armors banks, culvert outlets and ditch lining against that scour.

Winters bring deep frost on the basin floor, tempered near the mountain front by chinooks that thaw the surface out of season. No published frost depth was found for Riverton, Lander or Dubois, and the local building department sets footing depth.

Choosing the right material

Natrona County sits in Central Wyoming and its ground spans more than one zone: Casper, the North Platte and the Casper Arch, plus the Powder River Basin. Fremont County sits in Wind River Country, on the Wind River Basin and the Wind River front.

The ground itself differs between the two.

That difference changes the base and drainage choice. Ground that drains differently or holds water differently needs a different answer at the base course and at the drainage layer, so match the material to the ground under your own job rather than to a neighbouring county.
