Gravel and Aggregate Delivery in Ennis, MT
Montana Rock Supply brings gravel and aggregate delivery in Ennis, MT to contractors and homeowners working on the valley floor. Crushed base course, the 3/4 minus material this part of Montana builds drives and pads from, anchors what we send out.
The ground here is gravelly alluvium and outwash in places, mixed with clay-rich basin fill that holds water instead of taking it.
Materials for Ennis Projects
Base and driveway surfacing is the work that shapes this page. Crushed base course, also called 3/4 minus or 3/4 crushed base, is a graded crushed material for driveways, shop pads, parking areas, and shed bases.
It packs into a firm surface because the fines and larger stone stay blended together. 3/4 Crushed Base Course is the standard base throughout Montana.
Under that base, pit run carries deep fill. Pit run gravel comes straight from the pit unprocessed, so it raises grade and builds a sub-base under a crushed base course or a road mix surface.
It is not a finished driving surface and it is not crushed. Pit Run goes in first.
For the surface itself, road mix surfaces a drive or a county-style lane. Montana road mix carries enough fines and clay binder to pack hard under a roller, which is why it is the usual driveway gravel on open ground.
Driveway Gravel finishes the job.
Drainage and specialty work call for different material. Washed rock, or 3/4 clean, has the fines washed out, which is the whole point in French drains, curtain drains, foundation drains, and downspout runs.
Washed Rock lets water move instead of trapping it.
For beds and paths, crusher fines (screenings) bed pavers and flagstone and surface packed pathways. Stone Screenings and Walkway Gravel both suit a finer, walkable surface.
Shredded mulch holds on slopes and in wind better than nuggets. Shredded Mulch works beds and tree rings.
Ground and Conditions in Ennis
Water is the driver across the Southwest and south-central mountain valleys. Snowmelt off the Great Divide, sudden summer thunderstorms landing on dry ground, and irrigation ditches crossing valley floors all push water at once.
Gravel basin fill takes it readily; clay-rich basin fill does not.
That split decides where a drainage layer earns its place. On ground that sheds water, a compacted base course holds up.
On the clay-rich pockets, water sits and a clean washed stone layer gives it somewhere to go instead.
Spring runoff and bank scour on the Jefferson, Madison, Gallatin and upper Yellowstone, plus gullying and debris flows off burned slopes, move material every year. Riprap armors stream banks, culvert outlets, coulees, and ditches against that push.
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 higher ground.
Hard overnight freezing with a daytime thaw runs through much of the year at these elevations, so frost heave in drives and roads is a normal condition rather than only a spring event.
