What is the difference between crushed stone and Natural Pea Gravel?

Crushed stone is angular, broken rock with sharp edges. Natural Pea Gravel is rounded, river-washed stone at about 3/8 inch. Angular stone interlocks under a load, which suits a base course or drainage bed. Rounded Natural Pea Gravel stays loose underfoot, which suits walkways, play areas and dog runs.

Should I order material by the ton or by the yard?

Both work, and the choice is yours at checkout. Each product page has a calculator to size the load before you order. Order by the ton when the material is weighed out, or by the yard when you are working from volume.

Which stone is best for drainage in Laramie County?

Start with washed rock, which is clean drainage rock with the fines washed out. It suits perimeter and curtain drains, foundation drains and downspout runs. For larger drainage beds and pipe bedding, 3/4 inch crushed stone is the open, free-draining size. Riprap handles bank and slope protection at high water.

Materials delivered in Laramie County

Base material in Wyoming is specified as crushed base.

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 grading letters and states that base shall be crushed base unless otherwise specified.

Finer material rounds out a load. Top Soil is screened and goes on lawns, grading and bed prep over thin, stony or alkaline native ground.

Mason Sand beds brick and block work and paver joints, and Washed Sand levels under flatwork and pavers.

For decorative work, Wind River Rock fills beds, borders and dry creek beds, and 3/8" Natural Pea Gravel suits walkways, play areas and dog runs.

Ground conditions across Laramie County

Across the Southeast high plains, soils are silty and wind-laid over soft Tertiary sandstone, siltstone and Ogallala gravel. Gravelly terraces and irrigated bottom ground sit alongside shrink-swell clays where Cretaceous shale reaches the surface.

Gumbo that swells and shrinks moves a drive, so a compacted crushed base course is what carries the surface. Wind is the other constant on this open, dry plains ground.

It blows dust off bare lots and strips unbound surfacing, which is why a fines-bearing material that knits together holds up better on a path than loose stone.

Water arrives fast. Cloudburst thunderstorms in late spring and summer fall on hard, dry ground, snowmelt runs off subgrade that is still frozen, and clay lenses hold water under a drive instead of releasing it.

That is where washed rock in a perimeter drain earns its place.

After wind, water cuts. Gullies and rills form in the draws, and high water scours banks.

Riprap armors those edges.

The freeze-free season runs about 125 days in the farmed valleys. Base, drive and paver work goes in from spring breakup into autumn, and frozen ground stops compaction through the winter.

Winters are cold, dry and open, with hard freezing and wide day-to-night swings. Chinooks off the Laramie Range thaw the surface and let it refreeze inside the same week, so gravel drives cycle all winter and heave in spring.

Frost depth is about 36 inches in Cheyenne and Laramie County, and the local building department sets footing depth.

Choosing the right material

Goshen County and Platte County sit on the same Southeast high plains ground as Laramie County. Silty, wind-laid soils over soft Tertiary sandstone, siltstone and Ogallala gravel, gravelly terraces, irrigated bottom ground and shrink-swell clays where Cretaceous shale comes up.

The ground itself is the same, so the base and drainage choices carry over. The largest hard-rock aggregate quarry in the state works gneiss west of Cheyenne, so Crushed Stone turns up in yards here that will not be seen elsewhere in Wyoming.
