Custer County, ID Gravel and Landscape Rock Delivery
Idaho Rock Supply brings gravel, stone and aggregate delivery in Custer County, ID to driveways, pads and drain work. Spring snowmelt and rain on snow scour creek banks and mountain roads here, and disturbed ground sheds sediment fast.
Road mix is the material that answers most of that. Order it online, by the ton or the yard, and a dump truck tips it on site.
Ground Conditions Across Custer County
Ground across the Central Idaho mountains and high valleys is thin and coarse over granite. It weathers down to sandy Stone Screenings, with glacial till and moraine around the valley heads.
Valley floors hold deep outwash sand and gravel. That ground drains fast where it is deep, which is the easy case for a base.
Shallow soil over bedrock is the hard case. Subgrade that is still frozen sends meltwater across the surface instead of down through it.
Once Stone Screenings is disturbed, it washes out readily. A base that is under-built on that ground will rut and lose its shape.
Timing matters as much as material. Snow and frozen ground close out base and paver work from late fall until the ground dries in late spring.
The reliable window runs from early summer to early fall. Long hard mountain winters bring deep snow and a heavy spring breakup that softens gravel roads and drives as the frost comes out.
Frost figures for the highest valleys vary by jurisdiction, and the local building official sets footing depth. Ask that office before you pour.
Materials Delivered in Custer County
Road mix is the base course under driveways, parking pads, shop floors and shed slabs. It is crushed base with the fines left in so it locks up under a roller.
Contractors also order it as 3/4 minus, or 3/4 inch minus. Same load, asked for by size.
On public works plans in Idaho, base material is written up as crushed aggregate in Type I and Type II. State highway work follows the ITD Standard Specifications, where Section 703.04 covers aggregate for untreated base, treated base and road mix and Section 703.11 covers granular subbase.
Round rock and cobble go into dry creek beds, borders and water features. Natural Pea Gravel suits patios, dog runs and play areas, though it rolls underfoot where chips do not.
Fill dirt brings a low spot up before a base course goes on top. Garden soil and mulch handle raised beds and tree rings.
Choosing the Right Material
Lemhi County shares this ground region, so the same reasoning carries over. Thin, coarse soil over Idaho Batholith granite, till and moraine at the valley heads, and outwash sand and gravel on the floors.
Blaine County spans more than one zone. Part of it sits on this mountain and high valley ground, and part drops onto the Magic Valley and the central Snake River Plain.
Butte County is different ground entirely. It sits on the Upper Snake River Plain and the eastern farm valleys, with young basalt flows and thin soil over much of the plain.
That changes the base choice. Basalt is shallow and often hard, so a pad there may need fill to build grade before any base goes down.
This county's problem is the opposite. Deep outwash drains fast, but shallow soil over bedrock holds meltwater at the surface.
Match the material to the ground under it. Road mix where you need a compacted base, pit run where you are filling or raising grade, drain rock where water has to move.
