Gravel and Aggregate Delivery in Boulder, MT
Montana Rock Supply brings gravel and aggregate delivery in Boulder, MT to driveways, shop pads, parking areas and shed bases. Crushed base course, the 3/4 minus Montana yards sell, does the heavy work under a drive or a pad.
Around Boulder you are often working over gravelly alluvium and outwash, with thin stony ground on the slopes above town. That ground decides which material fits and how much of it you want.
Materials for Boulder Projects
Base and driveway surfacing is where a project here starts, and crushed base course leads it. Also called 3/4 crushed base course, it goes down under drives, shop pads, parking areas and shed bases.
Order it as 3/4 Crushed Base Course.
Pit run is unprocessed pit gravel, not crushed material. It suits deep fill, raising grade, and sub-base beneath a crushed base course or a road mix surface.
It is not a finished driving surface. Order it as Pit Run.
Road mix, also called 3/4 road mix, surfaces a drive or a county-style lane. Montana road mix carries enough fines and clay binder to pack hard.
Order it as Driveway Gravel.
Washed rock, also called drain rock or 3/4 clean, has the fines washed out, which is the whole point. It belongs in French drains, curtain drains, foundation drains and downspout runs.
Order it as Washed Rock.
Crusher fines, or screenings, bed pavers and flagstone and surface a packed path. Washed sand levels and beds flatwork and pavers.
Screened topsoil and garden soil cover thin or stony native ground and raised beds.
Rounded stone works elsewhere. Natural Pea Gravel suits walkways and play areas, river rock builds decorative beds and dry creek beds, and riprap armors a bank or a culvert outlet.
Ground and Conditions in Boulder
Water arrives as snowmelt off the Great Divide and as sudden summer thunderstorms falling on dry ground. Irrigation ditches cross valley floors.
Where that water goes decides what a drive or a pad needs underneath it.
Gravelly alluvium and outwash shed water readily. Clay-rich basin fill does not, and it holds what falls on it.
On the ranges that ring the valleys, soils are thin and stony over rock.
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, not only a spring event.
Frost depth is set locally: about 36 inches is the figure commonly used in Bozeman and about 48 inches in Helena, with deeper figures on high ground. The local building department sets footing depth.
Spring runoff and bank scour work on streams and coulees, and burned mountain slopes can gully and shed debris. Riprap armors the places water hits hardest.
The working season is short. Base, driveway and paver work runs from late spring into early autumn on the valley floors, and shorter again along the Divide.
