Crushed Stone, Sand and Gravel in Superior, MT

Montana Rock Supply offers gravel and aggregate delivery in Superior, MT to contractors building pads and drives and to homeowners fixing up a yard. Both kinds of buyer end up asking the same question: which material actually fits the ground here.

That ground varies block to block, from silt and clay to river gravel, so crushed base course is a common starting point and soil is often the missing piece.

Materials for Superior Projects

Grading and bed prep usually start with what is missing rather than what is on top. If your native ground is thin or stony, a load of soil does more for a lawn than any stone.

Top Soil is screened for lawns, grading and bed prep over ground that will not grow much on its own. For raised beds and planting areas, Garden Soil gives you a mix that native clay or gravel cannot match.

Fill Dirt raises grade and backfills before a base course goes down. It is bulk fill, not a surface, so it belongs under the finished layer rather than at the top of it.

Once grade is set, base and drainage materials take over. 3/4 Crushed Base Course, also called 3/4 minus, is the standard Montana base for driveways, shop pads and shed bases.

Washed Rock is the clean drainage rock for French drains, curtain drains and downspout runs, where washing the fines out is the whole point. Yellowstone River Rock covers decorative beds, borders and dry creek beds, and holds up in a dry climate better than bark.

Ground and Conditions in Superior

Water is the first thing to think about across the Western intermontane valleys. Valley floors carry glacial lake silt and clay that drains slowly and stays soft well into spring, while the river gravels beside them drain fast.

Snowmelt off the surrounding ranges keeps area rivers up through May and June, so spring is when ground water and runoff both peak. On a silt bench, that means timing matters as much as material.

Silty valley ground has to dry out before it will compact. Working it wet leaves you with a soft pad that never tightens up, which is why a long season still has a narrow window on the wetter sites.

High water also does damage. Bank scour at high water, gully cutting in silt benches and heavy runoff off burned ground after a fire summer all move soil you would rather keep in place.

Riprap armors culvert outlets and stream banks against that push.

Valley winters cycle the ground too, with hard overnight freezing, inversions pooling cold air on the floor, then chinook thaws that heave a gravel surface. Frost depth figures are set locally, and the local building department sets footing depth.
