How deep should a gravel driveway base be in Caribou County?

No single depth fits every site. Frost depth here runs about 30 inches as a figure commonly used around Pocatello and the southeast valleys, and the local building official sets footing depth. Silt loam over limestone and sandstone drains slowly, so a drive on this ground needs a base that carries traffic without pumping. Set your depth from your own ground and use, not a rule of thumb.

How much gravel do I need for my project?

Each product page has a calculator to size the load. You order by the ton or by the yard, and the quantity you enter is the quantity that arrives. Have your area and your planned depth in hand before you start. Ordering the right amount the first time keeps a long rural approach from a second haul.

Caribou County Road Mix and Gravel Delivery, ID

Idaho Rock Supply brings gravel, stone and aggregate delivery in Caribou County, ID to driveways, shop pads, drain runs and garden beds.

Road mix is the base most of that work starts from, and it is the term Idaho yards use for crushed base with the fines left in so it locks up under a roller.

This is Southeast Idaho valleys and the Bear River country, where the ground is loess and silt loam over limestone, sandstone and older sedimentary rock. Order by the ton or by the yard and a dump truck tips the load on site.

Ground Conditions Across Caribou County

A thin base shows itself fast in this country. Silt loam takes water slowly, so spring thaw and summer cloudburst runoff sit on the surface and work the fines out of a shallow lift.

The result is ruts, soft spots and a drive that pumps mud at the edges. Loess ground also gullies where water crosses it, and grazed or cropped slopes cut fast.

Across the Southeast Idaho valleys and the Bear River country, water coming off the ranges reaches the valley floors faster than silt loam can take it. Coarse gravel fans where the canyons open out carry sudden flows across building ground.

Low land near the Bear River and Bear Lake stays wet into early summer, so drainage matters as much as base thickness on those sites. Cold valley winters bring hard freezing and frequent swings either side of freezing, with heavy heaving on roads and drives at the spring thaw.

About 30 inches is the frost depth figure commonly used around Pocatello and the southeast valleys. The local building official sets footing depth for your project.

Base and paver work runs from the spring thaw into the fall. The higher valleys around Soda Springs work a shorter window than the lower ground down toward Pocatello.

Materials Delivered in Caribou County

Road mix is the material to know here. Also called 3/4 road mix, road base or crushed base, it is crushed rock with the fines left in, and it goes under driveways, parking pads, shop floors and shed slabs.

Idaho writes base material two ways. State highway work follows the ITD Standard Specifications for Highway Construction, where Section 703.04 covers Aggregate for Untreated Base, Treated Base and Road Mix and is the source of the 3/4 inch minus gradation, and Section 703.11 covers aggregate for granular subbase.

City, county and highway district work is usually written to the Idaho Standards for Public Works Construction, whose Section 802 covers crushed aggregate in Type I and Type II and Section 801 covers uncrushed aggregate. A contractor ordering 3/4 minus and a homeowner ordering road mix are asking for the same load.

Beyond the base, Idaho yards carry clean rock, round rock, sand and soil. Snake River Rock and Large River Rock cover decorative beds, borders and dry creek beds, while Stone Screenings bed pavers and fill joints.

Delivery Across Caribou County

You order online, choose a quantity by the ton or by the yard, pick a delivery date at checkout, and a dump truck tips the load in one pile on site. Each product page has a calculator to help size the load.

Bulk delivery reaches Soda Springs, Grace, Bancroft and Wayan, along with the rural ground between them. Rural approaches are long, so ordering the right quantity the first time matters.

Rip rap for a creek bank or a culvert outlet arrives the same way as a load of road mix. Everything is sized before checkout and tipped where the truck can reach.

Choosing the Right Material

Bannock County and Franklin County sit in the same region and the same ground as Caribou County. Loess and silt loam over limestone, sandstone and older sedimentary rock, with deep valley alluvium between steep ranges and coarse gravel fans at the canyon mouths.

So the base and drainage choices are the same ones: road mix for a compacted base, pit run underneath it where grade has to come up, and clean drain rock wherever water needs a path out.

Bonneville County is the one that differs. It spans more than one zone, covering the Upper Snake River Plain and the eastern farm valleys as well as the Central Idaho mountains and high valleys, so ground there can change sharply from one site to the next.

On a mixed site, expect to sort out what the ground under the base actually is before settling on a depth. Pit run and drain rock carry more of the work where soils change across a lot.
