Bulk Aggregate Delivery Across Weston County, WY

Wyoming Rock Supply brings gravel, stone and aggregate delivery in Weston County, WY to Newcastle, Upton, Osage and Four Corners. Crushed base, also called 3/4 minus or road base, is the standard Wyoming base material for drives, pads and lanes.

Weston County spans two very different ground regions, the Black Hills and the Bear Lodge on one side and the Powder River Basin on the other. That split shapes what you order and how you build on it.

Materials Delivered in Weston County

Crushed base is the material to start with. In Wyoming it is specified as crushed base, not as a numbered class.

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.

Order crushed base for driveways, shop and shed pads, parking areas and county-style lanes. It goes down as a compacted base, and it is talked about by top size, as 3/4 minus.

Pit run is unprocessed pit gravel. It is not crushed and it is not a finished driving surface; it goes in for deep fill and as sub-base under a crushed base course.

Scoria, also called red rock or clinker, is Wyoming's burnt-coal clinker, dug in the Powder River Basin. It works for paths, walkways, drives and pads where sound natural aggregate is scarce.

Washed rock, also called drain rock or 3/4 clean, is for perimeter and curtain drains, foundation drains and downspout runs. Crusher fines bed pavers and flagstone and surface pathways that need to hold together.

Riprap, or armor rock, lines stream banks, culvert outlets, draws and ditches and protects slopes against spring runoff. Screened topsoil covers lawns and bed prep over thin, stony or alkaline native ground.

Delivery Across Weston County

You order online, choose a quantity by the ton or by the yard, and pick a delivery date at checkout. A dump truck then tips the load on site as one pile.

Each product page has a calculator, and the calculator is the way to size a load. Quantities are ordered by the ton or by the yard, so decide which unit you want before you order.

Bulk delivery covers Newcastle, Upton, Osage and Four Corners. Have the drop spot clear and reachable by a dump truck before the load arrives.

Ground Conditions Across Weston County

Weston County spans the Black Hills and the Bear Lodge around Newcastle and Four Corners, and the Powder River Basin around Upton and Osage. Each side fails a thin base in its own way.

In the Black Hills and the Bear Lodge, you get limestone, sandstone and gypsum hogbacks, red-bed soils in the valleys, and thin stony ground over rock on the ponderosa slopes. The Mowry and Belle Fourche shales carry the Clay Spur bentonite bed, which is a genuinely difficult subgrade.

In the Powder River Basin, bentonitic gumbo clay weathers off Cretaceous and Paleocene shale and is cut by badlands and draws. Red clinker ridges, called scoria here, mark where coal seams burned out.

That clay sheds water rather than taking it in. Snowmelt sits on frozen subgrade, and local foundation details commonly over-excavate the clay and replace it with compacted granular structural fill for exactly this reason.

Erosion follows the same split. In the Black Hills and the Bear Lodge, rill and gully cutting works on steep slopes and in the red-bed valleys, with bank scour at high water and wind on the open ground west of the hogback.

In the Powder River Basin, wind crosses open ground, gullies and rills cut in shale badlands and coulees, and banks scour at spring high water. Riprap and a clean drainage layer are how you answer both.

The working season is short on both sides. Base and paver work runs from spring breakup into autumn, and in the basin wet gumbo has to dry before it will compact, which shortens the spring end further.

Choosing the Right Material

Crook County sits in the Black Hills and spans the Black Hills and the Bear Lodge plus the Powder River Basin, so its ground matches Weston County's. The same base and drainage choices apply there.

Campbell County sits in the Powder River Basin, with the same bentonitic gumbo clay, badlands, draws and scoria ridges. Sound natural aggregate is scarce enough across the basin that scoria is used as sub-base and surfacing where nothing better is close.

Niobrara County is different ground. It sits in the High Plains, with silty wind-laid soils over soft Tertiary sandstone, siltstone and Ogallala gravel, plus shrink-swell clays where Cretaceous shale reaches the surface.

That difference matters at the base. Shrink-swell clay moves under a drive, so a compacted granular base and clean drainage carry more of the load there than they would over stable ground.
