Thin soil over young basalt is common across the upper Snake River Plain, so what sits under a slab matters as much as what sits on it. Order online and a dump truck tips your load on site.

Materials delivered in Bonneville County
Base work starts with road mix, also called 3/4 road mix or 3/4 minus. It is crushed base with the fines left in, and it locks up under a roller.
Idaho writes base material up under the ITD Standard Specifications for Highway Construction, where Section 703.04 covers aggregate for untreated base, treated base and road mix. City, county and highway district work usually follows the Idaho Standards for Public Works Construction, whose Section 802 covers crushed aggregate in Type I and Type II.
Ground conditions across Bonneville County
Bonneville County spans two ground regions. On the upper Snake River Plain and the eastern farm valleys around Idaho Falls and Iona, young basalt flows sit under thin soil across much of the plain.
Basalt close to the surface leaves water nowhere to go, so drives and footings sit on thin ground over rock. Canal seepage and heavy spring irrigation lift the water table under low farmed ground.
In the Central Idaho mountains and high valleys around Swan Valley and Irwin, soils are thin and coarse over granite. Glacial till and moraine sit around the valley heads, with deep outwash sand and gravel on the valley floors.
Coarse ground drains fast where it is deep, but shallow soil over bedrock and subgrade still frozen send meltwater across the surface. Spring snowmelt and rain on snow scour creek banks and mountain roads, and Stone Screenings washes out readily once disturbed.
Frozen ground stops compaction from late fall to early spring on the plain. In the mountains, snow and frozen ground close out base and paver work until the ground dries in late spring.
Frost depth figures are set by the local building official, so check with the office that covers your site before footing work.
Choosing the right material
Bingham County and Madison County share Bonneville County's ground region, so the material logic is the same there: young basalt under thin soil, river sand and gravel along the Snake and the Henrys Fork, and deeper irrigated silt loam on the farmed ground.
Caribou County is different. Its ground runs to loess and silt loam over limestone, sandstone and older sedimentary rock, with deep valley alluvium and coarse gravel fans where the canyons open out.
That finer, silty ground holds water longer than basalt does, so drainage matters earlier in the build. Base and drain rock choices shift to suit it.
