Crushed Stone, Sand and Gravel in Elmo, MT
Montana Rock Supply handles gravel and aggregate delivery in Elmo, MT for two kinds of buyers: contractors building drives, pads and drainage, and homeowners fixing the same ground on a smaller scale. Crushed base course is where most of that work starts, and it is the material this area orders by name as 3/4 minus.
Elmo sits in Lake County, in the wetter northwest corner of the state where glacial till and outwash meet lake silt and clay on the valley floors below.
Materials for Elmo Projects
Base and driveway surfacing carries the load here, because the ground under it decides how the rest of a project holds up. The question is which material fits the job in front of you.
Base and Driveway Material
3/4 Crushed Base Course, also called 3/4 minus or crushed base, is the standard Montana base material for driveways, shop pads, parking areas and shed bases. It carries fines that bind the stone together under a roller.
Driveway Gravel, known locally as 3/4 road mix, is a surfacing material. Montana road mix holds enough fines and clay binder to pack hard as the finished surface of a drive or a county-style lane.
Pit Run is unprocessed pit gravel. It goes in as deep fill, to raise grade, or as sub-base under a crushed base course rather than as a driving surface.
Washed Stone and Sand
Washed Rock, also called drain rock or 3/4 clean, has the fines washed out, which is the point when you are running a French drain, a curtain drain, a foundation drain or a downspout line.
Stone Screenings, or crusher fines, bed pavers and flagstone and surface packed pathways. Washed Sand beds and levels under flatwork and pavers and acts as concrete sand.
Soil, Fill and Decorative
Top Soil is screened for lawns, grading and bed prep over thin or stony native ground. Fill Dirt handles bulk fill, backfill and raising grade before a base course goes down.
Yellowstone River Rock is rounded river-washed stone for decorative beds, borders and dry creek beds, the usual alternative to bark in a dry climate.
Ground and Conditions in Elmo
This is the wettest corner of Montana. Rain and snowmelt come off steep forested ground, and the Flathead, Kootenai and Clark Fork run high into early summer.
Under all of it, the deep lake silt and clay on the valley floors drains slowly. Water that cannot move down sits, and a drive over that ground has to be built to shed it.
The erosion side matters too. Runoff off logged and burned slopes, stream bank scour at spring high water, and wave action along Flathead Lake and the reservoirs all move ground.
Riprap and clean drainage stone are the usual answers.
Winters here are wetter and a little milder than the rest of the state, with heavy mountain snow. The ground freezes and thaws repeatedly through the season instead of locking up once, and gravel drives heave at breakup.
Around Kalispell, about 42 inches is the figure commonly used for frost depth, and the local building department sets footing depth. That work runs from breakup into late fall.
Saturated spring ground and frozen winter ground both stop proper compaction.
