3/4 Minus and Bulk Aggregates for Hill City, ID
Idaho Rock Supply brings gravel and aggregate delivery in Hill City, ID to driveways, pads and building sites. The base material here is road mix, also called 3/4 road mix or 3/4 minus.
It is crushed base with the fines left in, so it locks up under a roller.
Thin, coarse soil over granitic ground is common across the Central Idaho mountains and high valleys. That ground drains fast where it is deep and sheds water where it is shallow, so the base course has to be built for both.
Materials for Hill City Projects
Washed stone is the material for moving water away from a house or a yard. It is clean and angular, with no fines to pack solid, so water passes through instead of sitting in it.
Idaho yards sell it as drain rock in 3/4 inch, 1 1/2 inch and 2 inch sizes.
Drain Rock goes into French drains, foundation drains, drywells, septic drainfields and downspout runs. It stays open where groundwater and roof water need a path out.
3/4 Road Mix is the compacted base under drives, parking pads, shop floors and shed slabs. Contractors on public works plans in Idaho specify the same material as crushed aggregate, called out by type.
Pit Run is unprocessed gravel straight from the pit, rock and fines mixed at whatever sizes the pit gives. It works as sub base under road mix, as structural fill and for filling holes and raising grade.
It is not a finished surface.
3/4" Crushed Stone is clean angular rock for drive surfacing, pipe bedding and drainage where the stone needs to stay put. 3/8 Chip is the finer size for pathways, leveling course and topping over a compacted base.
Chips are angular, so they knit together instead of rolling underfoot.
Top Soil is screened and clean, for lawns and bed prep over thin desert soil, basalt ground and stony mountain ground. Garden Soil is for raised beds and planting areas where the native ground is too thin, too stony or too alkaline to plant into.

Ground and Conditions in Hill City
The working season here is the shortest in the state. 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, so timing a delivery matters.
Long hard mountain winters bring deep snow and a heavy spring breakup, and the frost coming out softens and ruts gravel roads and drives. Building officials in the highest valleys use deep footing figures.
Any footing depth is set by the local building official.
Coarse granitic and outwash ground drains fast where it is deep. Shallow soil over bedrock and subgrade that is still frozen push meltwater across the surface instead.
Spring snowmelt and rain on snow scour creek banks and mountain roads, and Stone Screenings washes out readily once it is disturbed.
That is the case for washed stone in drainage work. A drywell, a downspout run or a foundation drain gives meltwater somewhere to go before it reaches the base under a drive.
