Rip Rap and Bulk Aggregates for Swan Valley, ID
Idaho Rock Supply offers gravel and aggregate delivery in Swan Valley, ID. We supply road mix, the crushed base with the fines left in that locks up under a roller, along with drainage stone, decorative rock, sand and soil.
Thin, coarse soils over granite and glacial till around the valley heads leave little to build on. The right stone fixes that.
Materials for Swan Valley Projects
Spring snowmelt and rain on snow scour creek banks and cut slopes across the Central Idaho mountains and high valleys. Coarse stone is how you hold that ground.
The materials below run from the heaviest armor down to the fines.
Rip Rap
Rip rap is the heaviest armor we carry. It goes on creek banks, culvert outlets, canal banks, pond edges and cut slopes where runoff would otherwise cut the ground away.
Size the stone to the energy it has to absorb. A bank taking snowmelt needs bigger rock than a gentle swale does.
See RipRap for the gradations.
Cobble and River Rock
Cobble, sold locally as cobble rock or large river rock, handles dry creek beds, drainage swales and borders, usually in the 2 inch to 10 inch range. Its weight keeps it in place on a slope.
Smaller Snake River Rock suits decorative beds and water features. Both are round rock, so they move water rather than lock together.
Road Mix and Pit Run
Road mix, also called 3/4 road mix or crushed base, is the base course under driveways, parking pads, shop floors and shed slabs. Contractors here also order it as 3/4 minus or as crushed aggregate on public works plans.
Pit Run is unprocessed gravel straight from the pit. Use it as sub base under road mix, as structural fill, or to raise grade before a base goes on.
Drain Rock and Chips
Drain rock, or 3/4 clean, is washed rock for french drains, foundation drains, drywells, septic drainfields and downspout runs. It is clean, so water passes through instead of pooling.
3/4" Crushed Stone surfaces drives and beds pipe where you want an angular rock that stays put. Smaller 3/8 Chip tops pathways and levels beds over compacted base.

Ground and Conditions in Swan Valley
This part of the state has the shortest working season in Idaho. 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. Schedule delivery inside that window so the ground is workable when the load lands.
Long hard mountain winters bring deep snow and a heavy spring breakup. Gravel roads and drives soften and rut as the frost comes out, which is the season that moves the most material around.
Coarse granitic and outwash ground drains fast where it is deep. Shallow soil over bedrock and subgrade that is still frozen send meltwater across the surface instead, so plan drainage before you surface anything.
Frost depth in Blaine County runs at least 32 inches, and building officials in the highest valleys use deeper figures. The local building official sets footing depth for your project.
