Road Mix, Sand and Gravel Delivery in Jerome County, ID
Water here either drops into fractured basalt and disappears or backs up where the soil over the rock is thin and tight. Idaho Rock Supply delivers gravel, stone and aggregate in Jerome County, ID for both cases.
Start with road mix. It is the base course that carries a driveway, a parking pad, a shop floor or a shed slab, and it locks up under a roller.
Order it online and a dump truck tips it on site.
Ground Conditions Across Jerome County
Across the Magic Valley and the central Snake River Plain, the ground is a thin blanket of loess and wind-laid silt loam over fractured basalt. Rock often sits within a few feet of the surface.
That shallow rock changes how a base behaves. Water that cannot soak away sits in the silt above it, and an under-built base moves under a loaded truck.
River gravel and sand run along the Snake, and rimrock and talus sit at the canyon edges. Irrigation canals and canyon springs keep parts of the valley floor wet through the season.
Wind strips dry bare fields, and cloudburst runoff cuts into canyon rims and coulees. Armor those edges with rip rap before the next runoff season.
Work runs from the spring thaw into late fall across the Magic Valley. Spring dust and an early fall freeze-up set the practical limits at either end.
Winters here are cold and dry, with hard freezing and repeated thaw cycles on open ground. No published frost depth was found for Jerome County; the Idaho code leaves the frost line to the local jurisdiction, so the building official sets it.
Materials Delivered in Jerome County
Order by the job. A driveway, a patio and a drain each take a different material.
Road mix, the base course
Road mix is what Idaho yards call crushed base with the fines left in. A contractor asking for 3/4 minus and a homeowner asking for road mix are asking for the same load.
State highway work follows the ITD Standard Specifications for Highway Construction. Section 703.04 covers Aggregate for Untreated Base, Treated Base and Road Mix, and it is the source of the 3/4 inch minus gradation.
City, county and highway district work is usually written to the Idaho Standards for Public Works Construction. Section 802 covers crushed aggregate in Type I and Type II, and that is how base is named on public works plans.
Order road mix for the base under a drive, a parking pad, a shop floor or a shed slab. It is a compacted base, not a finished surface.
Stone, sand and soil
For drainage, order drain rock in 3/4 inch, 1 1/2 inch or 2 inch. It suits french drains, foundation drains, drywells and downspout runs.
For a patio or a walkway, Natural Pea Gravel is round and rolls underfoot. 3/8 chip is angular and stays where it is put.
For beds and borders, river rock and cobble cover ground and line dry creek beds. Bark mulch holds moisture through a dry Idaho summer.
Sand comes two ways. Washed concrete sand beds pavers and slabs, and mason sand suits brick and block work and paver joints.
Soil is screened and clean. Screened topsoil goes over thin desert soil and basalt ground for lawns and beds, and garden soil fills raised beds where the native ground is too thin or too stony to plant into.
Fill dirt brings a low spot up before a base course goes on top. It is structural fill, not a growing medium.
Choosing the Right Material
Twin Falls County, Cassia County and Minidoka County all sit in the Magic Valley and on the central Snake River Plain. Their ground is the same as Jerome County's: loess and wind-laid silt loam over fractured basalt, with rock close to the surface.
Because the ground matches, the base and drainage choice does not change from one of those counties to the next. A compacted road mix base and a clean drain rock layer answer the same conditions on all four.
Match the material to the job instead. Road mix for a base, drain rock for water that has to move, chips for a walkable surface, and rip rap where runoff meets a slope.

Questions About Base Material in Jerome County
When is the best time of year to order base material in Jerome County?
Work runs from the spring thaw into late fall across the Magic Valley, with spring dust and an early fall freeze-up as the practical limits at either end. Order inside that window and the ground takes a load and holds it.
Outside it, frozen or saturated ground will not compact the way a base needs to.
What is the difference between topsoil and fill dirt?
Topsoil is screened and clean, and it is what you plant into over thin desert soil, basalt ground or stony mountain ground. Fill dirt is structural fill: it backfills, raises grade and brings a low spot up before a base course goes on top.
One grows things, the other carries weight.
What is road mix and what is it used for in Jerome County?
Road mix is crushed base with the fines left in so it locks up under a roller. It is the base course under driveways, parking pads, shop floors and shed slabs.
State work specifies it under ITD Section 703.04, and public works plans call the same material Type I or Type II crushed aggregate.
