Gravel and Aggregate Delivery in Norris, MT
Montana Rock Supply brings gravel and aggregate delivery in Norris, MT, and the material this market builds on is crushed base course. That is the 3/4 minus a driveway, a shop pad or a shed base is made of.
Locally it is still called crushed base course, and it is the same stone that carries a top surface of road mix.
Ground here is gravelly alluvium in places and clay-rich basin fill in others, so the material under your project changes from lot to lot.
Materials for Norris Projects
Base and driveway surfacing is where most Norris work starts, and the base term to know is crushed base course. It packs hard under a roller and takes the weight of trucks turning in.
Over that base, road mix is the driveway surface. Montana road mix carries enough fines and clay binder to lock up as a driving surface, which is why it is the standard choice for a lane or a county-style approach.
Pit run is unprocessed pit gravel. It goes in as deep fill and to raise grade beneath a crushed base course, never as a finished driving surface.
Washed rock, also called drain rock or 3/4 clean, is the clean stone for French drains and foundation drains. The fines are washed out, which is the whole point.
On the sand and soil side, washed sand beds flatwork and pavers, and screened topsoil goes down over thin or stony native ground before a lawn or a bed.
Ground and Conditions in Norris
Water drives everything here. Snowmelt off the Great Divide, sudden summer thunderstorms on dry ground, and irrigation ditches crossing the valley floors all put water into the ground at once.
Across the Southwest and south-central mountain valleys, gravel basin fill takes that water readily. Clay-rich basin fill does not, and it holds moisture instead.
That matters for your base. A drive over clay-rich ground needs a drainage layer that can move water away, which is where washed rock belongs.
Spring runoff and bank scour are the other local force, along with gullying off burned mountain slopes. Riprap armors a stream bank or a culvert outlet against that push.
The working season is short. Base, driveway and paver work runs from late spring into early autumn on the valley floors.
Frost heave in drives and roads is a normal condition at these elevations, not only a spring event, because hard overnight freezing with a daytime thaw runs through much of the year.
