Crushed Stone, Sand and Gravel in Downey, ID
Idaho Rock Supply brings gravel and aggregate delivery in Downey, ID to rural yards, long approaches and building pads across Bannock County. Road mix leads the list, with the washed stone, sand, soil and decorative rock that finish the job.
Ground here is loess and silt loam over older sedimentary rock, so a load that locks up matters more than a load that looks tidy.
Materials for Downey Projects
Base and driveway surfacing is where most Downey ground work starts, and road mix is the local name for it. Road mix, also called 3/4 road mix, is crushed base with the fines left in so it locks up under a roller.
It carries the base course under driveways, parking pads, shop floors and shed slabs.
Ask for the same material by size and you are asking for 3/4 Road Mix. A contractor ordering 3/4 minus and a homeowner ordering road mix are asking for the same load.
Public works plans in Idaho name it crushed aggregate and call it out by type rather than by a class number.
Under that base, 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.
For the drive itself, Driveway Gravel surfaces an existing drive or tops a compacted road mix base on a long rural approach. 3/4" Crushed Stone is angular rock that stays put, used for drive surfacing, pipe bedding and drainage.
Where water has to move, Drain Rock is clean angular rock for french drains, foundation drains, drywells, septic drainfields and downspout runs. It comes in 3/4 inch, 1 1/2 inch and 2 inch sizes.
Sand and soil round out a build. Washed Sand beds pavers and slabs and goes into concrete work.
Top Soil is screened and clean for lawns and bed prep over thin soil and stony ground.
Ground and Conditions in Downey
Water comes off the ranges onto the valley floors faster than silt loam can take it. Alluvial fans at the canyon mouths carry sudden flows across building ground, and low land stays wet into early summer.
That is why a drive or pad needs a base that locks up and a drainage layer that gives the water somewhere to go. Road mix with the fines left in compacts into a surface that sheds; drain rock under a footing or behind a wall lets water pass instead of ponding.
Snowmelt and thunderstorm runoff cut canyon roads and fans, and bank scour follows the same flows. Gullying shows up on grazed and cropped loess slopes, so grade and surface both matter before the ground softens.
Base and paver work runs from the spring thaw into the fall. Higher valleys see a shorter window than the lower ground, and the spring thaw is when heaved drives show what the winter did.
Cold valley winters swing either side of freezing and heave roads and drives hard at thaw. Frost depth around Pocatello and the southeast valleys is commonly cited near 30 inches, and the local building official sets footing depth for Downey.
