Bulk Gravel and Stone Delivery in Boise County, ID
Idaho Rock Supply brings gravel, stone and aggregate delivery in Boise County, ID. Road mix is the base material this county runs on, the crushed base with the fines left in so it locks up under a roller.
It goes under driveways, parking pads, shop floors and shed slabs from Horseshoe Bend up to Idaho City, Garden Valley, Placerville, Lowman and Banks.
Ground Conditions Across Boise County
This county spans two ground regions. Around Idaho City, Garden Valley, Placerville and Lowman the soils are thin and coarse over granite that weathers to sandy Stone Screenings.
Around Horseshoe Bend the ground is old lake silt, sand and clay with basalt beneath, and hard caliche layers sit under thin desert soil on the benches.
Both conditions punish an under-built base. Water perches on caliche and on shallow basalt, and disturbed granite washes out once it is opened up.
Drainage layers and clean rock matter as much as the base course in these yards. Spring snowmelt and rain on snow scour creek banks and mountain roads, so armoured edges and rip rap hold where bare ground will not.
Timing splits the same way. In the mountains, snow and frozen ground close out base and paver work from late fall until the ground dries in late spring.
Around Horseshoe Bend the working season runs from an early spring thaw into late fall. Frost depth is about 24 inches in Boise and the surrounding Treasure Valley cities, and the local building official sets footing depth.
Materials Delivered in Boise County
Order by the job you are building. A driveway starts with 3/4 Road Mix, which is road mix, and finishes with Driveway Gravel on the surface.
A patio or path wants a compacted base under an angular chip or a round decorative rock. A drain wants clean washed stone with no fines in it.
Road mix carries the most weight in this county. Public works plans here name it crushed aggregate in Type I and Type II under Section 802, or uncrushed aggregate under Section 801 of the Idaho Standards for Public Works Construction.
State highway work runs on the ITD Standard Specifications instead. Section 703.04 is where the 3/4 inch minus gradation comes from, and Section 703.11 covers granular subbase.
Choosing the Right Material
Boise County shares its Treasure Valley ground with Ada County and Gem County. Old lake silt, sand and clay over basalt, with caliche under the benches, is the same material across all three.
Elmore County sits on that same ground region as well. There is no ground difference to plan around between these counties.
What changes is elevation and how fast the ground drains. Thin granite soil sheds meltwater instead of soaking it in, so a drive cut into a slope needs clean rock behind it to move water away.
On the caliche benches, water stops where the sand meets the hardpan. A drainage layer keeps the base from sitting wet through the spring.
Match the material to the surface you want. Round rock like Snake River Rock and Large River Rock suits beds and dry creek beds.
Angular chips and crushed rock suit surfaces that take traffic. Stone Screenings bed pavers and fill joints, and Washed Sand beds pavers and slabs.
