Ground and Conditions in Big Arm
Across the Northwest forests, Flathead and Kootenai country, the ground runs to glacial till and outwash with deep lake silt and clay on the valley floors. Gravel benches sit above that silt, and the forested slopes carry thin stony soil over rock.
Bedding fails on ground like this when the subgrade moves under it. Silt and clay hold water, and wet subgrade pumps and shifts under a paver course.
A thin bedding layer over soft ground shows the movement as rocking slabs and open joints.
This is the wettest corner of the state. Rain and snowmelt come off steep forested ground, and the lake silt on the valley floors drains slowly under all of it.
Plan the drainage layer before the surface layer.
Winters here freeze and thaw repeatedly through the season instead of locking up once, and gravel drives heave at breakup. Base, driveway and paver work runs from breakup into late fall.
Saturated spring ground and frozen winter ground both stop proper compaction.
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 here. Riprap armor belongs at culvert outlets and on exposed banks before spring high water.
Materials for Big Arm Projects
Start with the bedding layer. Crusher fines, sold locally as screenings or stone screenings, bed pavers and flagstone and pack into a firm, tight surface.
They set the grade the surface follows, so they carry the flatwork.
Washed sand levels and beds under flatwork and pavers, and doubles as concrete sand. Mason sand is the finer choice for brick and block work, paver joints and play sand.
Both are washed and screened, so they hold a line under a straightedge.
Crushed base course, also called 3/4 crushed base course or 3/4 minus, is the standard Montana base material. It goes under driveways, shop pads, parking areas and shed bases, and it is what you build up to before bedding goes down.
3/4 Crushed Base Course is specified locally by top size.
Under the base, pit run handles deep fill, raising grade and sub-base. It is unprocessed pit gravel, not a finished driving surface.
Pit Run goes down first where the grade needs lifting.
For a driving surface, road mix carries enough fines and clay binder to pack hard under a roller. Driveway Gravel surfaces a drive or a county-style lane.
Drainage needs clean stone. Washed Rock, also called drain rock or 3/4 clean, is washed so the fines are out, which is the whole point in a French drain, curtain drain or downspout run.
3/4" Crushed Stone works for drainage beds, pipe bedding and construction entrances.
Decorative work runs to rounded stone. Yellowstone River Rock fills decorative beds, borders and dry creek beds, and holds up where bark breaks down in a dry climate.
Large River Rock takes dry creek beds, splash pads under downspouts and heavier erosion work.
For lawns and beds over thin or stony native ground, Top Soil is screened and ready to grade. Garden Soil fills raised beds and planting areas where native clay or gravel will not do on its own.

Questions About Big Arm Aggregate Orders
What gravel is best for a driveway in Big Arm?
Road mix, also called 3/4 road mix or driveway gravel, is the usual surface here. It carries enough fines and clay binder to pack hard under a roller.
Build the sub-base with pit run where grade needs lifting, then crushed base course, then road mix on top. That layered build handles the wet ground and the repeated freeze and thaw this part of Montana sees.
How much material will my project need?
Quantities are ordered by the ton or by the yard. Each product page has a calculator to size the load, so you can match the quantity to the area you are covering.
