Riprap and Bulk Aggregates for Dillon, MT
Montana Rock Supply handles gravel and aggregate delivery in Dillon, MT, by the ton or by the yard. Crushed base course is the standard base material for drives, shop pads and parking areas around Beaverhead County.
Dillon sits in the Southwest and south-central mountain valleys, where gravelly alluvium and outwash cover much of the basin floor. That ground takes water readily, which shapes what you put on top of it.
Materials for Dillon Projects
Coarse stone does the heavy work on slope, swale and bank protection here. Spring runoff and summer storms move water fast across open ground, and the right rock size decides whether a bank holds or cuts away.
Riprap is the heaviest option. It armors stream banks, culvert outlets, coulees and ditches, and it holds slope faces against runoff.
Large, angular stone is what makes that work.
Large River Rock suits dry creek beds and splash pads under downspouts. It is rounded river-washed stone, so it moves water rather than locking into a wall.
Railroad Ballast is coarse, open rock for hard standing, track beds and severe drainage. It stays open so water passes instead of ponding.
For drainage that has to stay clean, Washed Rock is the choice. The fines are washed out, which is the whole point in French drains, curtain drains, foundation drains and downspout runs.
3/4" Crushed Stone and 3/8" Crushed Stone cover drainage beds, pipe bedding and construction entrances. The smaller size beds trenches and tops a compacted base.
Delivery to Dillon and the Surrounding Area
You order online and pick a delivery date at checkout. Quantities are ordered by the ton or by the yard, and each product page has a calculator to size the load.
A dump truck tips the load in one pile on site. Plan where that pile lands before the truck arrives, because the driver tips and leaves.

Ground and Conditions in Dillon
The working season is short. Base, driveway and paver work runs from late spring into early autumn on the valley floors, and shorter again on high ground.
Snowmelt off the Great Divide, sudden summer thunderstorms on dry ground and irrigation ditches crossing valley floors all drive water. Gravel basin fill takes water readily; clay-rich basin fill does not.
That difference decides how a site drains. Where clay holds water, a drive needs an open drainage layer before anything goes on top.
Hard overnight freezing with a daytime thaw runs through much of the year at these elevations. Frost heave in drives and roads is a normal condition here, not only a spring event.
Published frost figures vary by town, and the local building department sets footing depth. Spring runoff and bank scour also drive erosion work, along with gullying and debris flows off burned slopes.
Questions About Stone and Delivery in Dillon
What stone should I use for drainage in Dillon?
Washed Rock is the standard for French drains, curtain drains and downspout runs because the fines are washed out and water passes freely. For drainage beds and pipe bedding, 3/4" Crushed Stone works well.
#57 Stone and #67 Stone are also sold for drainage and concrete work, usually asked for by inch size locally.
What should I have ready when the truck arrives?
Have the drop spot clear and reachable. A dump truck tips the load in one pile, so the ground where it lands should be firm and free of overhead wires or low branches.
