Idaho Rock Supply brings gravel and aggregate delivery in Troy, ID, from road mix for driveways and parking pads to topsoil for lawns. If you are building on loess ground across the Palouse hills, the base course is where the work starts.
Order online, size the load by the ton or the yard, and a dump truck tips it on your site.
Materials for Troy Projects
Road mix is the base course under driveways, parking pads, shop floors and shed slabs. Idaho yards call it crushed base with the fines left in, and it locks up under a roller.
Contractors here also order it as 3/4 minus, which is the same load by size.
On public works plans around Latah County, this same material is specified as crushed aggregate by type. If a plan calls out Type I or Type II crushed aggregate, it is the base course you are pricing.
Under that base, pit run is unprocessed gravel straight from the pit, rock and fines mixed at whatever sizes come out. Use it as sub base, structural fill, or to bring a low spot up before road mix goes on top.
It is not a finished surface.
For the driving surface itself, 3/4" Crushed Stone is angular rock that stays put under tires and works as pipe bedding and drainage stone. Driveway Gravel surfaces an existing drive or tops a compacted base on a long rural approach.
Where water has to move, Drain Rock is clean washed 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.
For bedding and concrete work. Top Soil is screened and clean for lawns and bed prep over thin, stony ground, and Garden Soil fills raised beds where the native ground is too thin or too alkaline to plant into.
Ground and Conditions in Troy
Across the Palouse hills and the Clearwater and Snake canyons, silt loam over loess seals under rain and sheds water instead of taking it in. Long slopes push that runoff onto roads, drives and yards, and water perches where the loess sits on basalt.
That is why a drive here needs a base that drains at the edges and a drainage layer where water collects. Sheet and rill erosion on cropped loess slopes in this part of the state is among the heaviest anywhere, and canyon roads, culverts and creek banks scour under spring runoff and summer cloudbursts.
Sticky loess mud through the wet months is the real constraint on hauling and compaction. Work goes best from late spring through fall.
Winters on the prairie bring frequent freeze and thaw.
Frost depth is left to the local jurisdiction, and the building official in Troy sets it. No published figure applies here, so plan footing depth with the official rather than from a number.
