What is the difference between topsoil and fill dirt?

Topsoil is screened and holds the organic content and texture that grass and plants need. Fill dirt is bulk material for backfill and raising grade before a base course goes down. Use fill dirt to build the grade, then topsoil as the planting layer over it. They are separate products and separate jobs.

What is crushed base and what is it used for in Teton County?

Crushed base is the standard Wyoming base material, also called 3/4 minus or crushed base course. It goes under driveways, shop and shed pads, parking areas and county-style lanes, compacted as the structural layer.

Q: How deep should a gravel driveway base be in Teton County?

There is no single figure that fits every lot here. Frost depth is 34 inches measured to the bottom of the footing for the Town of Jackson and Teton County, or the depth a soils engineer sets for the site. Ground conditions vary from coarse outwash to slow silt, so the base depth follows the site.

Wyoming Rock Supply handles gravel, stone and aggregate delivery in Teton County, WY. Crushed base is the standard Wyoming base material, and it is what a drive, a shop pad or a parking area is built on here.

The building season in Jackson Hole is the shortest in the state. Snow holds the ground into late spring, so the window for base and driveway work is squeezed at both ends.

Ground Conditions Across Teton County

Snowmelt drives everything in this corner of Wyoming. A heavy snowpack comes off the Tetons, the Gros Ventres and the Salt River Range into the Snake and the Salt, and spring water tables rise on the valley floors.

Across the Jackson Hole, Star Valley and the Snake River country, the ground runs from glacial outwash and cobbly river gravel to deep silt and clay. Coarse outwash can sit next to slow silt, so two lots on the same street can drain nothing alike.

That mix decides how a base course and a drainage layer get built. Ground that sheds water quickly still needs a compacted base under it.

Ground that holds water needs the water moved away from the base.

Frost is deep and long here. Snow lies on it and holds the ground frozen into late spring, then it releases all at once.

The published frost depth is 34 inches measured to the bottom of the footing for the Town of Jackson and Teton County, or the depth a soils engineer sets for the site.

Spring high water scours banks on the Snake, the Gros Ventre and the Salt. Fast runoff and debris come off steep fan ground, and cut slopes rill before they revegetate.

Delivery Across Teton County

You order online and a dump truck tips the load on site in one pile. Quantities are ordered by the ton or by the yard, and each product page has a calculator to size the load.

Pick your delivery date at checkout. Coverage runs to Jackson, Wilson, Alta, Kelly, Moose and Moran, along with the surrounding county ground.

Have the drop area clear and reachable before the truck arrives. A bulk load needs room for the truck to tip and pull away, and the pile lands where the truck stops.

Choosing the Right Material

Park County sits in the Bighorn Basin, the driest ground in the state, where the lower basin takes only 5 to 8 inches of precipitation in a year. Its alkaline and saline silt and clay sit over Cretaceous shale, gypsum and bentonite beds.

That is a different set of problems from Teton County, where snowmelt and high spring water tables are the design assumption. A base course here has to shed meltwater, not wait on scarce rain.

Sublette County sits in the Green River Basin, Red Desert and the southwest valleys, cold high desert between 6,000 and 7,500 feet. Its soils are alkaline and saline, with dune fields and cobbly outwash and terrace gravel.

Both neighbours are drier and their ground is more alkaline than the outwash, till and river gravel found here. Where water is scarce, drainage matters less to the base choice than it does in Teton County.
