What is road mix and what is it used for in Elmore County?

Road mix is crushed base with the fines left in so it locks up under a roller. Idaho yards also call it 3/4 road mix or 3/4 minus, and a contractor asking for 3/4 inch minus wants the same load. Here it goes under driveways, parking pads, shop floors and shed slabs, and it is the base course that a drive surface sits on.

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

No single depth fits every site. The ground matters more than the number: clay lenses, basalt and caliche layers under the valley ground hold water, while sandy terraces drain faster. Use the calculator on the product page to size the load once you know the area you are covering.

How much gravel do I need for my project?

Each product page has a calculator that sizes the load for the area you are covering. Order by the ton or by the yard, then choose a delivery date at checkout. The truck tips the load on site in one pile, and you work it from there.

Elmore County Road Mix and Gravel Delivery, ID

Idaho Rock Supply brings gravel, stone and aggregate delivery in Elmore County, ID to homes and job sites from Mountain Home out to Glenns Ferry, Hammett and King Hill.

Road mix is the base most ground here is built on. It is crushed base with the fines left in, so it locks up under a roller, and it goes under driveways, parking pads, shop floors and shed slabs.

Materials Delivered in Elmore County

Road mix, also called 3/4 road mix or 3/4 minus, is the base course for drives and pads. In Idaho it is specified two ways: ITD Standard Specifications Section 703.04 covers aggregate for untreated base and road mix, and public works plans name crushed aggregate by type.

Coarser stone comes in larger sizes for heavy work. RipRap armors creek banks, culvert outlets, canal banks and pond edges against snowmelt and cloudburst runoff.

Pit Run is unprocessed gravel straight from the pit, used as sub base under road mix, as structural fill and for filling holes and raising grade. It is not a finished surface.

Mid sizes handle drainage and drive surfaces. Drain Rock is clean angular rock for french drains, foundation drains, drywells and septic drainfields, sold in 3/4 inch, 1 1/2 inch and 2 inch.

3/4" Crushed Stone surfaces drives and beds pipes where an angular rock that stays put is wanted.

Finer grades cover paths, bedding and sand work. 3/8 Chip tops a compacted base on pathways and leveling courses, and its angular shape knits together where round gravel rolls.

Washed Sand beds pavers and slabs and mixes into concrete. Top Soil builds lawns and beds over thin desert soil and stony ground.

Ground Conditions Across Elmore County

The working season here runs from an early spring thaw into late fall, the longest in Idaho. Canal water runs from spring to autumn, and that governs when work along ditches and laterals can happen.

Across the Treasure Valley and the western Snake River Plain, old lake silt, sand and clay sit over basalt. Hard caliche layers lie under thin desert soils on the benches.

Water that gets through the sand stops at the caliche and sits.

Clay lenses and shallow basalt perch water under yards and drives. Where that shows up, a clean drainage layer under the base gives the water somewhere to go instead of holding it against the slab.

Summer cloudbursts run straight off crusted desert soil instead of soaking in. Spring wind moves dry bare soil, and cut slopes along canals and ditches scour under runoff.

Riprap and cobble hold those banks where the ground will not.

Winters bring many shallow freeze and thaw cycles rather than one deep freeze. Frost depth is about 24 inches in Boise and the surrounding Treasure Valley cities, and the local building official sets footing depth.

Delivery Across Elmore County

You order online and pick a delivery date at checkout. Quantities are ordered by the ton or by the yard, and each product page has a calculator if you want to size the load before you check out.

A dump truck tips the load on site in one pile. Delivery covers Mountain Home, Glenns Ferry, Hammett and King Hill, along with the rural ground between them.

Choosing the Right Material

Camas County lies in the Magic Valley, over thin, coarse soils on granite that weather down to sandy Stone Screenings and glacial till.

That ground drains differently from the caliche and clay layers under the valley side, so a base there often needs less drainage stone under it than one built over a perched water table.

Boise County spans more than one zone, mixing mountain ground with the Treasure Valley and western Snake River Plain. Where it sits on the valley ground, the silt, clay and caliche conditions match what you build over here.

Ada County shares the same ground region as Elmore County, the Treasure Valley and the western Snake River Plain. The silt, sand, clay and caliche are the same, so the material choice follows the same reasoning.
